I know in a hydronic heating system using radiators, water will take the easiest path all day. One radiator would be full hot and the other would get zero flow and be cold. It doesn’t take two routes unless it’s forced to do so via a “balancing valve”, which is installed to throttle the water going the easier path to equalize flow. Your system might work - and it sounds like it does- but it’s more luck than anything if that’s the case. An easy test would be to run the pump before the outlet side of the Venturi and the filter are connected and see if water flows out of both. If it doesn’t,, an inline valve on the route that has the flow could be installed and incrementally closed until good flow is observed from the other route.
In this instance, the venturi is the "balancing valve." This setup keeps the plumbing system running the most efficiently - filtering, creating the vacuum/suction and minimizing loss of total overall flow in your plunge.
Thanks for your thorough videos, bought a 150 gal Rubbermaid tank and found you quickly after. Gunna enjoy the cold weather for now, but planning to build come springtime!
Something to consider in the future would be adding a threaded union joint between the two 90 elbows. In the event you ever needed to swap out the filter cap or the Venturi (both with threads) you could do so without having to reconstruct the entire assembly. Great video, thanks for putting this out there!
I just found your instagram feed and saw that you included that on one of your recent builds! That’s awesome, thanks again for sharing all this going to start gathering materials to build my own!
@@DIYColdPlungePVC union slip joints at home Depot $7.11 each, the plain PVC fittings are about .80 cents. I couldn't justify the price even though it's a good idea.
Great videos Joe! I've already gotten a ton of useful info from them. I don't think I'd be building my cold plunge without you. I'll no doubt make a video of my build for my channel to go along with my timber frame sauna build. Will be sure to point viewers in your direction.
I guess putting the filter and venturi in parallel could work, as long as there's flow through each one. You're gonna have some unfiltered water going thru the venturi, and some plain water going thru the filter, but after enough time (and assuming there's flow thru both) the water will end up being clean and sanitized enough.
Even if you put the filter and ventur in-line, as soon as the water hits back to the tank would be "unfiltered"... The only way to truly filter the water would be to go from one tub to another anyway. This simplifies the plumbing setup and operates the most efficiently for water sanitation.
It seems the norm is to run the filter system after the chiller/pump (mine is a combo unit), why is that? Wouldn't we want to filter the water before it hits the expensive chiller, to prevent sand/dirt getting into the chiller? Why run it after?
To protect it from ozone, and to prioritize suction at the venturi. Any debri that gets through the strainer, & pump (in my opinion) likely won't harm the chiller.
I am a little confused about this setup. Isn't the resistance for flow through the venturi injector much smaller than through the mechanical filter? I would expect most water to flow through the Venturi injector (path of least resistance) and the filter only catching heavier particle that land in the lower branch due to gravity. Does your filter get dirty at all? Am I misunderstanding this set up? Is the flow resistance of the venturi injector comparable to the filter, is that why it is working?
Hey! The filter definitely gets dirty. Because the venturi condenses down, majority of the water flow goes through the filter. Gravity doesn't contribute much to the system at all, its all flow-based.
@@DIYColdPlunge Maybe a strainer upstream of the filter/sanitation would be a good idea to catch sediment that may find its way through the Venturi and into the cooler? Thanks for the great DIY. Adding this setup to my Ice Barrel 300.
Question… on the exit side of the filter/venturi, why couldn’t you just put a T joint where the 90 elbow is thats bringing the ozone treated water back towards the filter. If you put a T instead of a 90 wouldn’t it allow the water to flow more easily? Basically the ozone treated water would not be coming back towards the filter and just exit straight down when meeting with the filtered water. Hope that makes sense.
Thank you so much, this is super helpful! I wanted to ask - the tub I have has 1/2 inch inlet and outlet which I can't change (inflatable). I'd like to follow your plans and use 3/4 inch for the filtration/sanitasion/chiller system. Do you think it's bad to use a 3/4 to 1/2 conversion at the tub's inlet and outlet?
I love this video it explains so much. I’ve been trying to build my own cold plunge. I can’t seem to find flexible pvc. Where did you buy it? Everywhere I go there’s just pex.
Thank you for such detail in your videos. I purchased your plumbing plans which are also very detailed and easy to read. One question I have regarding the filter model for the GE filter is GE GXWH20S however the links take me to the GXWH20T; is this the same filter?
Are you filtering after the chiller? Also, have you considered or experimented with a smaller diameter hose from the chiller to the plunge? My thought is it would slow the return in the chiller making it more efficient (colder).
I think you need to put the filter and injector in line. now half of the water is filtered and half is ozone treated. if they are inline (one after the other) then 100% of your water is treated in both ways. or did I miss something? really asking
I like your thinking! Most pumps will output between 1000-1800 gallons/hr. On a 100 gallon tank (that probably has 80ish gallons in it) the water changes over many times. Ozone generators should run at least an hour, maybe 2-3 depending on overall use so majority of the water will see ozone a few times over during that time span. Putting the venturi exclusively in line would greatly reduce the flow rate, affecting overall water circulation and making the pump work a lot harder. The ozone will also meet up with the water after it runs through the filter anyway. This configuration is the best of both worlds.... I totally realize this is a ramble but long story short this keeps the water moving so more water overall can be both filtered and "ozoned" 😂 Does that make sense?
I was wondering the same question, but that was a great response! I understand both thought trains but after hearing your explanation this system seems perfect
All these comments make sense...but to get the best of both worlds it seems like the parallel part should be after the filter. That way all water is filtered, then some is split off to the venturi tube for ozone, then rejoins the rest. Anything wrong with that scenario?
@@jwgreene2the thinking here is so the venturi also acts as a bypass in the case of the filter becoming plugged. This would prevent the pump or chiller from burning out if the filter plugs
I also think that @jegreene2 is correct, I sell some ozone diluted in water systems and what we struggle the most is that for some reason the Venturi gets clogged,and then we have to unclogged by running water in reverse, when you pass your water without filtration through your vinturi you can also get the same problem of getting it clogged. And in your system there is no way to run water the opposite way to fix it.
Hey Joe! Love the videos. Can you tell me what connection I need on the Venturi injector you sent me? It’s different threads than the one in this video, almost looks like barbed. Thanks in advance!!!

First off thanks for the video with all the links. I bought all the components listed and got it all set up. Only issue is the ozone does not seem to be injecting any air into the line. Any advice on what might be the issue?
Whats different in your updated assembly plan that I have to dish out money for? Does this set up not work or something? I want to know before I consider buying the plan and all the parts? Thanks for your help
Hello quick question. I built a cold plunge out a stock thank and am using a inline filter right after my drainage line. Water isn’t crystal clear and now I’m thinking of using a water filter like you have in the video. Due to installation it may not be possible to install the new filter in place of inline filter/stainer could I install it before my return valve? The line that send the water back Into the cold plugs after the chiller? That line has more space to accommodate the size of this thing. Or does the filter have to be installed by the drain line
Does this design allow some water to go through the pump and not get filtered? It seems like the water is either being filtered or being ozonated, but not both. Could you just put the black venturi injector piece inline?
I have another video that talks through some of it, but you don't want to restrict water flow that much. And as soon as the filtered water hits the tub, it's no longer "filtered." You'd need to filter into a new tank for all the water to get filtered in one shot.
I see there's a cut off valve at the filters so you don't have to put cut off valves in the Plumbing to change the filter and will it keep the water running through the pump so? You. Don't? Have. To cut the pump? Off also. Or do you have to cut the pump off too
Did you order the 3/4" venturi? I'm guessing that would be the issue. The ozone generator hasn't changed. I do offer and upgraded venturi & filtration plan on my site diycoldplunge.com/
Will the water not follow the path of least resistance thus just bypass the filter ? Additionally why not just add the Venturi at the end and save yourself lots of effort ?
You will drastically sacrifice flow putting them in line with each other. With a small closed loop system like this your water turns over many many times throughout the day filtering the water without issue.
800 gph active aqua pump discharging into the chiller that discharges into a 30 micron ge whole home filter. Since adding the filter the flow has come to a crawl. Is my pump not generating enough pressure to pass through a pleated water filter?
Is the water filter actually needed? I’m not sure why the filter is needed aside from debris and what not getting in the water, but maybe it’s necessary! Thanks!
I'm curious, why set the filter and venturi injector up in parallel and not in series? Is it just for looks/tidiness of the install, or is there a functional reason as well?
is it possible or would it be better in line vs parallel to each other? Like have single flow of water go first through the filter and then through the ozone so its treated with both? vs having some water be treated with ozone and other water be treated with filter?
No, it would restrict flow too much. Your tank will turn over many many times throughout the day so your water will be treated and filtered many times over.
Will this setup work if you have a pump/filter combo upstream? In other words, you create a bypass that is just a simple tee, one outlet that leads to the venturi and the other is straight pipe or tubing that joins at the other end of the venturi?
That should work, there's nothing special about having the filter below, this is just the most space-conscious setup if you are starting from scratch. I would put the ozone first as it needs a certain amount of PSI to create the suction 👍
Where do you get the wall bracket for the GE whole house filter? We purchased the filter from Home Depot and it doesn't come with a wall mount bracket.
Thanks for this video! Wouldn't the flow rate of this filter create an issue since it is listed as 4 GPM (240 GPH) and the Danner Pump is rated at 1200 GPH? Sounds like you are going to restric the flow a lot no? Thank you!!
That was a thought of mine too.. at the end of the day I modeled this after "The Plunge" and used the parts/specs they have. Mine has worked well so far. You can take a peek at the flow at the end of this video ua-cam.com/video/Dr5WrZaQrCo/v-deo.html
@@DIYColdPlunge But there is no filter element inside the housing at the end of the video. The element would be the limiting factor. Well, if it's working for you I'm guessing it'll work for me and the Danner 900 I have.
Yes - It works with the filter in the housing. I wouldn't keep this up if it didnt. And, any loss in flow through the housing would only make the venturi work better by prioritizing flow there.@@REBooner30
I did this setup. How do you know if the air from the generator is actually pumping into the venturi? I can't tell if it's working properly or not. Thanks.
Here's what I used - www.menards.com/main/plumbing/hoses-tubing/pool-spa-tubing/sioux-chief-3-4-id-x-10-l-flexible-spa-hose/900-16300w00101/p-1470660864012-c-8582.htm?tid=ae3e06b9-26c4-4402-8c30-44ccbeb5ac81&ipos=4&exp=false
Majority of the water is going through the filter. Just enough is going through the venturi to create the vacuum. If everything was in line it would GREATLY reduce flow.
A pool pump would work great in that case, as long as it has the power to create a suction for the venturi. You would also want to skip the filter part of this - most pool pumps come with a filter built in.
@@DIYColdPlunge The Danner 1200 is out of stock. If we have a 150 gal rubbermaid (obviously not filled to the top), would the Danner 950 (#02710) work?
@@DIYColdPlunge I have an intex pump. Are you still recommending using just the filter in the intex or should I use a double filter (intex + ge filter)?
Whats the reasoning behind setting it up in parallel like this? If it was full flow through the filter then past the ozone Venturi you could likely run a smaller pump and lower overall electrical consumption. Am I missing something?
The main reason is to maintain the flow rate of the water - which most want for a few reasons. The venturi injector needs a certain PSI to create suction. Your chiller also needs water to move at a certain rate to function efficiently and keep the water cold. The electrical consumption difference on a pump is going to be extremely minimal. From a user experience standpoint, moving water will break down the thermal barrier your body creates.
What kind of pump are you using? So far I manually clean my plunge and it’s annoying!!!! Already ordered everything I could. (Plungebuddy ozone generator is sold out). Thanks!!!
Looking for advice from anyone What is the best way to get the water moving and through the filter? I have an oak barrel and want to avoid drilling holes. Could I use a submersible pump into a filter and have this under my seat?
@@DIYColdPlunge just one other question regarding this...could I run it from the submersible pump, through a pool filter (also submerged as it is sealed) and then straight back out into the bath itself?
The pump is slightly more powerful than the flow rate of both, the flow rate of the filter is significantly more than the Venturi. Water follows the path of least resistance.
Hey there! I tried this setup with the newest venturi on your site with 3/4 barbed fittings, but the 3/4 adapter does not fit. Is there a step I'm missing?
No... and even if it did, as soon as it returns to the tank it would be in contact with unfiltered, unsanitized water. The only way to get 100% filtered water would be going from one tank to an empty tank. The number of times the water turns over through the system is the key.
Are you going to make videos to help with the paid designs/plans on your website? Kinda like a start to finish like this for each past? In/out, drainage, etc. Thank you!
I notice your layout in this video is different from the "DIY Filtration & Sanitation System Plan" on your DIYColdPlunge website. is one layout better or more efficient than the other?
Hey! the ozone tube can pop off with a little bit of force, there isn't really a need to have a shutoff specifically for the ozone - but I did incorporate shutoffs and unions in my plumbing design to replace/service each component (pump, chiller, filtration, etc.)
The filters I have tried seem to get clogged after about a week of use. Does that sound right? They are 1 micron filters. I will try the recommended ones, but I'm just wondering if anyone else has seen that.
Nice work, replicating that expensive Plunge set-up. I'm looking to do the exact same thing with my Rubbermaid tub. I take it you're gonna be using bulkhead fittings for return hose? Does your friends Plunge have a pump on the return line coming from the filter. From pics I've seen the Plunge tub has two pumps an intake ambohr wp-D800 pump and some other pump for the return I believe it's a Jeboa. I take it that's for better circulation in the tub, but not really necessary. I'm currently gathering all the parts for my build. Good luck with yours, curious to see what you do.
Thanks Jamie. Ill use bulkheads to go back to the stock tank. I don't believe there was a dual pump setup. Is that what you have seen? I'm curious if you have pictures of that. My friends goes pump, chiller, filter/ozone, then heat (bc his is hot and cold) and then returns into the tub
Hey Joe. With more research I figured out what it was, it's a Jebao PU-18 Pond and Aquarium Clarifier. It uses a UV bulb in that long chamber, which aids in sanitation and water clarity. I initially thought it was a pump. I saw the image in one of their Plunge filter removal/change videos on UA-cam. I was looking at getting the jebao DCT-6000 it's rated at about 1,500 gph. That's assuming I get the penguin 1/2hp chiller. What are your thoughts
@@Jptl07 aah that makes sense. I just looked that pump up, never heard of it before. I think it should work great. I have a Danner Aqua-Mag 1200 that I really like and the flow is in that same range. I may have to bite the bullet and test the DCT-6000 as well.
Do you see any issues with putting the tee for this, after the filter? so running into filter, then out to a loop with the ozone generator within it? My concern would be putting this inline with the filter might eventually lead to sediment debris clogging the line since it's receiving non-filtered water.
You could set this up a number of ways, and what you outlined makes sense if I'm visualizing it correctly. BUT, if you have some sort of strainer cap, that shouldn't happen. And if anything, it would affect your pump not the filter/venturi. No wrong way to go about this though!
If you are using ozone indoors you will want to very closely monitor it - from what I have read it seems the recommendation is to run it for a small interval each day when it won't be in use, make sure there is a tight lid on the tub and have a fan/ventilation available if needed. I personally can't speak to it, my setup is outside

Quick question… the linked Ozone gen has a tiny hose attachment too small for the Venturi tube. Did I miss something?
Did you order the 3/4" venturi? I'm guessing that would be the issue. The ozone generator hasn't changed. I do offer and upgraded venturi & filtration plan on my site diycoldplunge.com/
Will the water not follow the path of least resistance thus just bypass the filter ?
Additionally why not just add the Venturi at the end and save yourself lots of effort ?
You will drastically sacrifice flow putting them in line with each other. With a small closed loop system like this your water turns over many many times throughout the day filtering the water without issue.
Didn’t know at the time the reduction the venturi provides … built your system works like a charm 👍🏼👌🏼
800 gph active aqua pump discharging into the chiller that discharges into a 30 micron ge whole home filter. Since adding the filter the flow has come to a crawl. Is my pump not generating enough pressure to pass through a pleated water filter?
I'd need to see the entire setup to assess that... You can send an email through my site if you want.
Understand . For sure makes sense . I'll figure it out. Just wasn't sure if ge 30 micron filters are known to slow flow down to a crawl
Is the water filter actually needed? I’m not sure why the filter is needed aside from debris and what not getting in the water, but maybe it’s necessary! Thanks!
The filter is there to collect debris 👍
I'm curious, why set the filter and venturi injector up in parallel and not in series? Is it just for looks/tidiness of the install, or is there a functional reason as well?
It's more to maximize flow rate and performance.
Does the black box (ozone generator) have positive pressure itself pushing air through the check valve?
It does not. It relies on the suction from the pump & venturi
Sweet design, can we see it added to your plunge and operating?!
I'll post a video soon!
Can this system be used on a hot tub ? I wanted to have a secondary filtration system to delay the water changing as long as possible?
Is this a DIY hot tub? I'm guessing an existing hot tub would have it's own system?
is it possible or would it be better in line vs parallel to each other? Like have single flow of water go first through the filter and then through the ozone so its treated with both? vs having some water be treated with ozone and other water be treated with filter?
No, it would restrict flow too much. Your tank will turn over many many times throughout the day so your water will be treated and filtered many times over.
Will this setup work if you have a pump/filter combo upstream? In other words, you create a bypass that is just a simple tee, one outlet that leads to the venturi and the other is straight pipe or tubing that joins at the other end of the venturi?
That should work, there's nothing special about having the filter below, this is just the most space-conscious setup if you are starting from scratch. I would put the ozone first as it needs a certain amount of PSI to create the suction 👍
Thank you for making this
You bet!
Can this be submerged under water? Sorry still learning before I go all in.
Yep, there have been folks that use this in a chest freezer setup
The 3/4” flexible PVC does not fit on my build. I think 1 inch would be good. Could you send me the link you used?
This is the spa hose I used - I do not carry 1" though. diycoldplunge.com/products/flexible-pvc-spa-hose
Can you run the ozone indoors without evacuating or need to evacuate the area while it’s on?
Running it on a timer is recommended.
Where do you get the wall bracket for the GE whole house filter? We purchased the filter from Home Depot and it doesn't come with a wall mount bracket.
Weird... it should have been in the package. I wonder if you got a return or something where someone didn't put it back in
If the primer/glue drips down and dries in the tubing is that an issue? What should I do to make sure it’s safe for water?
It will cure, you should be good 👍
you could just run some water through and then drain
Thanks for this video! Wouldn't the flow rate of this filter create an issue since it is listed as 4 GPM (240 GPH) and the Danner Pump is rated at 1200 GPH? Sounds like you are going to restric the flow a lot no? Thank you!!
That was a thought of mine too.. at the end of the day I modeled this after "The Plunge" and used the parts/specs they have. Mine has worked well so far. You can take a peek at the flow at the end of this video ua-cam.com/video/Dr5WrZaQrCo/v-deo.html
@@DIYColdPlunge But there is no filter element inside the housing at the end of the video. The element would be the limiting factor. Well, if it's working for you I'm guessing it'll work for me and the Danner 900 I have.
Yes - It works with the filter in the housing. I wouldn't keep this up if it didnt. And, any loss in flow through the housing would only make the venturi work better by prioritizing flow there.@@REBooner30
Would I be able to hook up 3/4 hose for my ice barrell cold plunge ?
For sure!
Have you measired actual flow rate? I think my setup is too restrictive. My danner 12 might be putting out roughly 200 gal/hr actual. 40 micron filter
40 micron is a lot, I use 20. Is yours traveling through a chiller?
I did this setup. How do you know if the air from the generator is actually pumping into the venturi? I can't tell if it's working properly or not. Thanks.
Hey Bob! You should see bubbles at the inlet of your tub if the system is creating suction.
Amazon doesn't sell the whole house filter system in your Barbed Ventury DIY plan anymore (gxwh20s) does GXWH04F work as a replacement??
Hey! There's a good number of people in my facebook group that use that one, otherwise I can still get that one at Home Depot. I'd check there.
If you have a 100gallon tub, how often are you running the ozone? That's not something you constantly run is it?
ive had success with 60 min/day 👍
How well does this filter skin and hair?
This filtration system has been great. Occasionally there are floating grass to scoop out and sand/dirt on the very bottom.
Any flexible tubing on Amazon.. it is 3/4 tubing right? 2 trips to Lowe’s no luck
Here's what I used - www.menards.com/main/plumbing/hoses-tubing/pool-spa-tubing/sioux-chief-3-4-id-x-10-l-flexible-spa-hose/900-16300w00101/p-1470660864012-c-8582.htm?tid=ae3e06b9-26c4-4402-8c30-44ccbeb5ac81&ipos=4&exp=false
Is the water going through the ozone generator by passing the filter? Why wouldn't you go through the filter first then the ozone generator?
Majority of the water is going through the filter. Just enough is going through the venturi to create the vacuum. If everything was in line it would GREATLY reduce flow.
can you do this one inch diameter with same system? thanks
The filter housing and Venturi are fitted for 3/4" - I've never tested 1"
Just Curious.....................why don't you use Pex?
Honestly because that's what the big brands used, and to me it's easier and the inner pipe diameter works best for how these are set up.
what if im running the intex pump with a built in filter? I wonder how i can hook up the venturi without restricting the whole system...
Create a little loop with the venturi on top and a ball valve below to help prioritize some flow to the venturi.
@@DIYColdPlunge thanks!
How often do you run the ozone generator? Just got the Venturi from your site! The new model one
I've been running 24/7 as a test (tub is outside) but anywhere from 30 min to 2 hrs a day will be plenty
Doesn’t it Needs a pump to circulate the water? Greet video thanks
Yep! I have a recommended parts PDF available showing all the components
If you are not using a chiller can you use a pool style pump or do you still recommend the danner 1200 type pump?
A pool pump would work great in that case, as long as it has the power to create a suction for the venturi. You would also want to skip the filter part of this - most pool pumps come with a filter built in.
@@DIYColdPlunge The Danner 1200 is out of stock. If we have a 150 gal rubbermaid (obviously not filled to the top), would the Danner 950 (#02710) work?
@@DIYColdPlunge I have an intex pump. Are you still recommending using just the filter in the intex or should I use a double filter (intex + ge filter)?
When connecting my ozone generator to the Venturi inductor does it matter if my ozone generator has a built-in pump?
Nope, it'll work the same as long as the check valve is in the right direction.
How often do you need to change the filter and the water?
I go every 3ish months.
My dancer 950 isn’t pulling water fast enough through this design. Idk what to do. The pump is gapping with air
You need to make sure water can freely flow to it. These pumps push, they don't pull/create their own suction.
GE has discontinued the recommended water filter system. Do you have any alternative suggestion?
I have a few other options in my parts and components guide - linktr.ee/diycoldplunge
You can use any household water filter and housing, that's what this is
If all of my current inlet and outlet water lines are 1” inch would I just copy this this system with 1” inch pvc ?
what pump and chiller are you using?
1 1/2 hp chiller from vevor@@DIYColdPlunge
the pump is OYO WATER 1600GPH Submersible /inline pump
I can't say for sure with that setup, but worth a test
@@jasongulvartian5163
ill try it and find some one inch adapters and see how it goes. @@DIYColdPlunge
Do you have your ozne on a timer? Or do you run it 24/7 with the pump?
Ozone is on a timer, everything else is 24/7. ua-cam.com/video/oBM_S9uYWDA/v-deo.html
will this be place in the wather ?? or out of it and only the tube will go in the wather
I have it outside of the tub
@@DIYColdPlunge so I don't really get it ! How did you put your tube in then ??
Could this be submerged in a DIY chest freezer plunge?
I'mnot sure on that... the filter would but I dont know about the ozone/potential for leaking.
Does this work without a chiller if you’re bulk ice cooling?
Yep!
How can I set this up properly without the chiller?
Any video of it in action?
I've got several shorts and other test videos on my channel 👍
How did you connect it to the chiller?
Spa Hose to PVC fittings 👍
@@DIYColdPlunge haha … i guess i should have said do you have any photos or or videos of how you connected it.
What stops the dirty water from just by passing the filter?
Flow is prioritized to the filter because the venturi reduces in size.
Whats the reasoning behind setting it up in parallel like this?
If it was full flow through the filter then past the ozone Venturi you could likely run a smaller pump and lower overall electrical consumption. Am I missing something?
The main reason is to maintain the flow rate of the water - which most want for a few reasons. The venturi injector needs a certain PSI to create suction. Your chiller also needs water to move at a certain rate to function efficiently and keep the water cold. The electrical consumption difference on a pump is going to be extremely minimal. From a user experience standpoint, moving water will break down the thermal barrier your body creates.
@@DIYColdPlunge so essentially to reduce flow past the venture and maintain flow everything else?
@@pearlpirate Yes, keeping a high flow rate
Can you still put Epson salt in the tub if you’re this system
I've never tested it. You could make a post in my FB group facebook.com/groups/diycoldplunge
What kind of pump are you using? So far I manually clean my plunge and it’s annoying!!!! Already ordered everything I could. (Plungebuddy ozone generator is sold out). Thanks!!!
Back in stock now!
@@DIYColdPlunge Sold out again :)
What would be the difference if I used 1/2 in pvc???
I would keep it consistent. The pump and filer housing are all 3/4"
Looking for advice from anyone
What is the best way to get the water moving and through the filter? I have an oak barrel and want to avoid drilling holes. Could I use a submersible pump into a filter and have this under my seat?
If you want to avoid holes, a submersible pump is the way to go. The Danner pumps I use and recommend can be submersed or used in-line 👍
@@DIYColdPlunge Amazing thank you very much
@@DIYColdPlunge just one other question regarding this...could I run it from the submersible pump, through a pool filter (also submerged as it is sealed) and then straight back out into the bath itself?
I can't see how the water goes through the filter?
The pump is slightly more powerful than the flow rate of both, the flow rate of the filter is significantly more than the Venturi. Water follows the path of least resistance.
hey why do you use threaded injector on this and have the barbed one on the website?
I've had more success with the barbed fittings. There was a high amount of leaking with people that ordered threaded venturi's from amazon'
@@DIYColdPlunge then you go straight into the soft pvc with it?
Hey there! I tried this setup with the newest venturi on your site with 3/4 barbed fittings, but the 3/4 adapter does not fit.
Is there a step I'm missing?
The spa tubing should slip over the barbed fitting, is that how you tried it?
@@DIYColdPlunge Ahh! That makes sense - I did not try that, but I will 👍🏾. Thanks!
so the water getting split to be sanitized by ozone doesnt get filtered?
No... and even if it did, as soon as it returns to the tank it would be in contact with unfiltered, unsanitized water. The only way to get 100% filtered water would be going from one tank to an empty tank. The number of times the water turns over through the system is the key.
Which configuration works better? This one, or the one you have posted for 22 dollars?
Depending on how the rest of your setup is configured, both work 👍
Thank you 🙏
🙏
How safe is ozone for the human body? Can't you have too much of it which will then persist in the water / air while you are there?
It's actually a common sanitizer in hot tubs and pools in some cases. It only needs to run an hour each day, and I have had no issues.
Which flexible Pvc were u using can u provide a link?

That's the plan! Working on it now 👍
I notice your layout in this video is different from the "DIY Filtration & Sanitation System Plan" on your DIYColdPlunge website. is one layout better or more efficient than the other?
The plan is more efficient 👍
Where does the pump fit into all of this?
ua-cam.com/video/RELc6xNzfLM/v-deo.html
Nice setup. Did you think about shutoffs in case you have to service the ozone generator?
I guess the check valve before the generator would suffice....
Hey! the ozone tube can pop off with a little bit of force, there isn't really a need to have a shutoff specifically for the ozone - but I did incorporate shutoffs and unions in my plumbing design to replace/service each component (pump, chiller, filtration, etc.)
The filters I have tried seem to get clogged after about a week of use. Does that sound right? They are 1 micron filters. I will try the recommended ones, but I'm just wondering if anyone else has seen that.
You'll want to change to 50 micron. Some use 20-30 as well, 1 is way too small.
Nice work, replicating that expensive Plunge set-up. I'm looking to do the exact same thing with my Rubbermaid tub. I take it you're gonna be using bulkhead fittings for return hose? Does your friends Plunge have a pump on the return line coming from the filter. From pics I've seen the Plunge tub has two pumps an intake ambohr wp-D800 pump and some other pump for the return I believe it's a Jeboa. I take it that's for better circulation in the tub, but not really necessary. I'm currently gathering all the parts for my build. Good luck with yours, curious to see what you do.
Thanks Jamie. Ill use bulkheads to go back to the stock tank. I don't believe there was a dual pump setup. Is that what you have seen? I'm curious if you have pictures of that. My friends goes pump, chiller, filter/ozone, then heat (bc his is hot and cold) and then returns into the tub
Hey Joe. With more research I figured out what it was, it's a Jebao PU-18 Pond and Aquarium Clarifier. It uses a UV bulb in that long chamber, which aids in sanitation and water clarity. I initially thought it was a pump. I saw the image in one of their Plunge filter removal/change videos on UA-cam. I was looking at getting the jebao DCT-6000 it's rated at about 1,500 gph. That's assuming I get the penguin 1/2hp chiller. What are your thoughts
@@Jptl07 aah that makes sense. I just looked that pump up, never heard of it before. I think it should work great. I have a Danner Aqua-Mag 1200 that I really like and the flow is in that same range. I may have to bite the bullet and test the DCT-6000 as well.
@@DIYColdPlunge will that pump have enough pressure to push the water through the filter in this video? Thank you, appreciate all your guidance!
@@chrisfreeman1054 Yep! I'll post a video showing it working soon.
What kind of pump should I use
I recommend Danner pumps
Can I run this submerged?
Yep!
Do you see any issues with putting the tee for this, after the filter? so running into filter, then out to a loop with the ozone generator within it? My concern would be putting this inline with the filter might eventually lead to sediment debris clogging the line since it's receiving non-filtered water.
You could set this up a number of ways, and what you outlined makes sense if I'm visualizing it correctly. BUT, if you have some sort of strainer cap, that shouldn't happen. And if anything, it would affect your pump not the filter/venturi. No wrong way to go about this though!
Which heater do you recommend?
I've got a link to the one I'm using on my site
Thank you
You're welcome
is this safe for an outdoor plunge?
If you are using ozone indoors you will want to very closely monitor it - from what I have read it seems the recommendation is to run it for a small interval each day when it won't be in use, make sure there is a tight lid on the tub and have a fan/ventilation available if needed. I personally can't speak to it, my setup is outside
