This was so much more detailed than i was expecting 😁 The go-pro angle under the sink was going the extra mile, good stuff!
Good job Richard. You're the man.
Have one of these with 4 filters. Water is great. 6 month replacement on a couple of the filters or 6000 gallons, and 24 months on the other two. Every year they say to clean the system and repressurize the tank with a bike pump. Really is good and convenient.
Which model or brand did you go with? I was looking for a descent kit with low maintenance costs.
@@gnhun101 www.espwaterproducts.com/aqua-flo-platinum-qcro-4-stage-ro-system/
Filters arent the cheapest, but the system works great. Really haven’t had to do much maintenance, just cleaning, filters, pressure once in awhile.
@@johnnyappleseed79 how much is the whole system?
any system that doesnt require me to cut my landlord's house
I install these things every once in a while. He should have been more clear after installation. It takes about 2 to 3 hours to fill the tank then you have to flush the tank once by running the filtered water for about 5 minutes then let the tank fill again. When the tank is full and with a proper tank precharge of 100 psi water will come out at a much higher pressure than we seen here.
Greg NY Plus while ROs generally install the same way concept wise, there are always small differences, and the potential for leaks is a big one whether it be from the unit or connections
Thank you for that
100psi?! I sure hope not.
@@fearofchicke thats what is labeled on the tank 100psi
@@scrappyny7432most RO system will tell you 1 of 2 ways to flush/purge the new system. 1: fill tank check for leaks, then open faucet and let run for 24 hours to clean system. 2: Fill and flush system 3 times to clear system.
Very detailed Nice job!!
Richard is life! Richard is love!
Richard is a white devil according to some.
I wish they would show how to cut through different types of counter tops for the RO faucet.
Many people don't have a extra hole to use.
A 3/8 drill bit ouht to do it and if it’s granite just use a diamond bit to make the hole!
@@armandocontreras5078 Hi. Thanks you. Do I need to make a pilot hole with a smaller bit first? Or just start with the 3/8?
Thanks
M depends what you’re drilling? If granite no
No pilot hole unless it’s 3/8” or smaller otherwise you may not properly center the larger bit
Same here
Setup is roughly $199 to $260 GE Reverse Osmosis Water Filtration System
I got one on Ali-Express for about $40 plus about $30 AUD more in parts / fittings from the hardware store :]
I was going to install one of these in to my apartment. I'm glad I saw this because I don't have Room for that return drain at all
Tim G they sell smaller drain clamps it doesn’t need that much space.
There are different variations of saddle drains. There is one that connects inline between the dishwasher drain and the garbage disposal.
just drill a small hole on the pvc for the discharge hose and put silicone. works good. no leaks. just make sure is on top of the p trap or else odors will get in your clean water 🚱
DRAIN SADDLE!
Nice
Get one. Put it in.
The third filter is used right before dispensing, AFTER the tank.
Wow good for you
I feel like this video is going to be a lot more popular here soon.
You see the court cases proving higher flouride in adults and kids cause neurologic damage lowering IQ it was blocked by the gov until a lawsuit they knew in may 22 but blocked us till now
He skipped the part where you fill up the storage tank and then drain it. If you don’t do this then the water will be impure and slightly discolored.
He's an idiot, what'd you expect
aren't yousuppose to let it run for a while before drink it?
I mean that's exactly what I was about to post I mean who would take the first glass of water after something produced in the factory then has probably residual Dustin things and I mean maybe I'm being a little over the top but I mean it tell you you shouldn't wear underwear clothing right out of the factory there's probably all sorts of production residual that can't be consumer-friendly but then again I'm sure if I measured all the crap it's gone into my body it's probably absurd,apples for arsenic lettuce anything sprayed any underwear vegetables potatoes are totally polluted when they give them to you that are inorganic I read that there are so many chemicals that go on radishes tomatoes lettuce all sorts of produce that are marginally deadly but then you can't get over the top can we?
LMAO
Yeah like 30 minutes you're supposed to flush the system with mine.
It was probably cut out for time saving purposes
@@acommentator69 cool. So how many people died from contaminated water?
Love the green screen walls in this house 😍
Can't tell if youse joking?
@@mike3177 He's talking about the bright green paint, clearly visible at 1:50
Right? WTH
Beautiful
The waste water connection from the r/o filter is supposed to be made before the waste disposal, not after. I see that it would be almost impossible with the single drain sink and the the disposal mounted that way. Unlikely but a backed up p-trap and the disposal could pressurize the r/o waste line. Would fail an inspection if it was installed when the house was built in my area (I know of 2).
So if you have a double sink, just attach the RO drain to the drain without the disposal?
@@Zyxi7 I put mine into the cross waste pipe , haven't had any issues whatsoever.
@@jcwoods2311doesn't make is right or code.
This guy needs some cordless power tools 😂joking.
Getting ready to do the same thing.
Good video
Thank you
Love it
Nice info. Can i install the drain tubing into the dishwasher inlet of the garbage disposal since i am not installing a dishwasher? Thoughts? Thank you
Yes. Supposed to be inserted pre-disposal connection though. Richard made a boo-boo on that one.
Can you please upload a video of how to change the filters?
We got one of the best water aquifers its filtered through volcanic lava rocks here in Dunsmuir CA.
I want to install a non-RO water filtration system with an alkalizer (similar to a countertop unit) to my refrigerator water line for filtered water and ice. Will this produce good results, and is the filter that’s installed in the fridge still necessary?
Why alkaline it when the watwr that you drink goes to your stomach and becomes acidic again 🤷🏾♂️
Do you have an issue with you liver or kiddies?
Great Video! We have a American Plumber WRO-3500 system and a 5 Gal. Tank. The tank was about empty in the morning after filling all night. Checked the water going into it and it's drops and not a flow or stream of water. What is the normal flow into the tank coming from the system? we just changed all filter, so they're all brand new. Is there another issue or blockage causing this? If so, where? Thanks!
Either pressure switch problem, or clogged membrane.
Most tanks need about 15psi internal to push the water out. You may be able to use a compressor to repressureize it to 15 psi. That's not much so be careful to not overcharge. Use a tire pressure gauge to check it.
Its worth it, unless you are on a cistern and have to haul your own water. And also waste water unnecessarily to the septic field
Why is there 2 black lines going to the faucet? Could I just go from system to drain and bypass the faucet connection? What's the purpose of going to the faucet with the drain lines? Thank you.
It's for backflow protection, its an air gap faucet that allows the waste water to pass through the body of the faucet
@@majulenparah thank you
Should add a alkaline filter in line ,ro water is of low ph acidic.
Watching this cause my plumber says he can't install the filter, due to not being able to turn off the hot water supply. I was confused because why should that be an issue, this only uses cold water?
Can be a hassle sometimes to no be able to shut both off at the same time. You should have angle stops at every fixture anyway.
Hire a real plumber.
He either hasn't a clue or doesn't want to do it...the hot and cold are separate
He don't want to do it
The carbon filter also filters chlorine.
Culligan recommend an RO system when installing a water softener in my first house. I have never looked back and an RO system will be the second priority item installed in my new house, only after internet! 🤣 However, this time, i can save myself 1200 bucks by doing it myself. Especially with that nifty valve.
How much does Culligan charge for an RO system? Is it a monthly price?
@@Matt34677 at the time, it was an additional $1200 after the $3000 for the softener. i was given a choice to pay it all at once or finance it.
Sprinkle a little Himalayan salt with each glass to add some bonus minerals and this will be the best water to drink.
So where's the connection from the filters to the collection chamber?
We had an osmosis system
Pit in but it the water coming out of the dispenser smells
Terrible
How do you connect ro system straight to refrigerator without going through the faucet?
Buy a John guest 3/8x1/4 tee. Install the tee in the 3/8 line leading to the faucet. Insert the 1/4 ice maker line. Enjoy RO water at your fridge.
I have a Apec RO90 Reverse Osmosis system it has a 4 gallon tank. In the manual it says it takes about 2-3hours to fill the tank. I noticed faucet never stops, water trickles endlessly after 1 hour. Is this normal? wouldnt faucet stop after the tank is emptied since it takes a while to fill the tank/filter water?
If the tank is empty, that is just your water production.
That is the membrane producing water.
Can anyone tell me what exactly is that red/maroon tank? Sorry absolutely new to plumbing and owning a house
Garbage disposal
Garbage Dispoal. I installed the exact same model under my sink and it's amazing, powerful and really quiet compared to the dryer full of bolts sound that others make when on.
Pure H20 implies distilled water, which one should not drink. He should have cautioned her about waiting for for the tank to fill then dumping the tank full of the water and NOT drinking it. Also, if you are in an area with high water bills (Monterey Peninsula, based on consumption) and non-existent summer rainfall, you might not want to throw away that much water. I ran the dump line under and out of my house, about 30', to two large rain barrels, one flowing into another, which hold the water for me to use on my back garden. The plants *love* the extra minerals and I save about 50 gallons a week.
You get the majority of your minerals from food though... Not water. So she will be fine
This comment is cringe Californian bullshit
Distilled water is not bad to drink. It wouldnt be what I relied on if I was a working in 100° heat as you arent replenishing the minerals you are sweating out, but there is nothing inherently bad about drinking it.
Does water consistently run with this system?
Who is relying on water to meet their nutritional needs?!
Hi
Is there a common part name for the valve that splits the cold water supply to the sink and the RO system?
3/8 compression T fitting
Reverse osmosis water is the purest water that I ever tasted...
I would have used a John guest fitting 3/8 by 3/8 by 1/4 for the cold water feed 😂
So no hose clamps at the barbed fitting?
No plumbers tape on that T valve eh?
This guy is hilarious, he's not a plumber or any licensed trade contractor. Yet, he poses as one and speaks with confidence while spewing misinformation. First, the correct order of the water is as follows, prefilter, RO membrane, storage tank, postfilter, finally faucet. Second, you MUST purge and flush all new RO system several times to remove factory disinfectants, carbon fines and any other undesirable items in the RO system. Also having 2 seperate shut off valves if the way to go, those tee's that stack leak. A true plumber would use tubing cutters on the tubular waste not a HACKsaw. One more point of mention is the drain must be made before the disposal. In this application the disposal would need to be eliminated for the RO system to be installed properly.
No flush? That system seems pretty cheap. There are plenty with extra “stages” and some that add minerals back in. I love my express water setup. Tastes great!
What you mean "Flush". This system discharge some water during filtering into drain for keep membrane clean. Discharge connection on 4:40.
You have to run water through the system to clean out the carbon. Also, the tank, has just been sitting there. You flush the system to clear air and impurities, and the system! Replace a filter in your fridge, throw away the first days worth of ice... same principle
They don't show a lot on TV. You don't think he really did this whole job in 6 minutes do you?
Correct,a good ro has a backwash valve, you should also add an alkaline filter, ro water is of low ph,acidic.
@@truth6600 whats the point when water that goes to ypur stomach becomes acidic again? 🤷🏾♂️
From someone who has installed and serviced r.os and other aspects of water treatment for 30 years, the ignorant comments here are laughable.
I agree 100%, and I never even did it professionally! 😀
Any suggestion for a way to get clean water if im a renter? I have the pur filter on my countertop but from what i see its not good enough also i have hard water. I see there are countertop reverse osmosis systems but im curious what you think
I've read that these aren't recommended for those using a septic tank.
Is that the case and what is the argument?
Never heard that before...I've heard garbage disposals and septic tanks are a no, no in general (but not all cases). No reason you can't have an R/O system with a septic tank.
maybe due to the increase of impurities (salts, heavy metals, etc.) from the effluent, but that's only remotely accurate if you're running hundreds of gallons per day. Even then, it would most likely be neutralized before it did any damage to the thousands of gallons in your septic.
Ryan Carlen if you dump pure water into a septic tank it runs right past the baffles to the leach field. Won't hurt it.
You probably don't want a whole-house water treatment system emptying into the septic. I think the concentrate of salt eats the concrete of the tank. The discharge from this system is miscible.
Is it possible to drill thru granite countertops to install the faucet?
J Rene of course
You can probably rent a masonry hole saw.
The filter needs to be filled and drained before consuming or else you could be drinking carbon dust which is extremely dangerous
not really dangerous but bad tasting and cloudy
Richard must have enjoyed working on this womans pipes. Rich is the boss.lol
What about for coffeemakers? How do you add minerals back in so that coffee doesn't taste flat?
Typically a 5 stage R/O system will have a mineral cartridge that reintroduces minerals to your water.
By buying a real system.
@@ChefBoyareB 5 stage ROs do not add minerals back into the water. If you are going to reply at least try to have some facts. The only systems that add alkalinity back in are the ones that have a mineral cartridge they are 6 stage and up. (5 stage RO's are generally a polypropylene sediment filter, granular activated carbon filter, carbon block filter, 0.0001 micron reverse osmosis membrane, and a post charcoal filter.
@Key Privacy I really wish there was a way to put a picture of me doing a facepalm here. If the water is undrinkable and needs an RO to improve its quality making coffee from unfiltered water completely defeats the purpose of filtering it in the first place.
@@thebigdoghimself and that's why I said "some have a mineral cartridge". If you want to reply, please read before you do.
you loose 1 to 2 gallons per 1 gallon filtered water?? Isn´t that a lot?
Inconsiderate and misleading parts: for the service, you better to have a separate angle stop valve for RO water inlet. Instead, only T was installed. Also you don't drink the water from the first filled tank as they have not been flushed. That water will have craps.
Price the replacement filters and the change out intervals. It will make your eyes water. Disposable water filter cartridges are like printer ink cartridges. Corporate $$$$$ making scheme. That you are locked into.
I'd rather go with a Alexapure system. Best in test I've seen. And one of the better prices.
Not really. Costs me $30 a year for consumables. If you have good raw water and good pressure filters can last quite a long time.
Jesus Christ, don't talk about stuff you know nothing about. I have a Watts premiere 5 stage unit. a years worth of filters runs under $40 on Amazon. I replace my membrane every two years and that runs about $50. Still, dramaticly cheaper than having 5-gallon water bottles delivered or having to deal with buying bottled water at the store.
John Salazar Exactly!👍🏼
Wtf??? You need to run the proper cycle after install. You CANNOT drink that water right after install.
They did. It's the magic of video editing. There's a cut right before she fills the glass. They do this all the time, the editors don't see that kind of stuff as necessary.
That takes a long time. The videos they put here are only like 6 or 7 minutes long.
You need to find a way to reuse that drain water
thats already done
there is a small drain hose that you can capture the waste water, i send that into my grey water system to water plants.
All water from my showers, washing machines, ro go into the grey water system to water plants, while water from the sink is filtered via sand/charcoal and is used for plants - always plants that are not for consumption. While our septic system leach field is near trees and they do great.
That is just how i handled our problems this might not work for you. Always look up your citys codes and ordinances to see if your project will work and is legal.
The only way to make sure you are treating your water correctly is to know what is in it. R.O. is great for many contaminants but not all. Treat according to the chemistry. Three stage five stage, know what you actually need, hire a professional, it's not the same as plumbing in a washing machine or a hot water heater! Water is dynamic not static.
What did he do with the second black line?
"hold the iron"... if the filtered water sits in a tank, doesn't that just put the iron back in?
Thanks madam. That will be $50,000 please.
Lol
U can't drink that right away, it's straight charcoal until u run the sediments out of the new filters. Y don't u just use a Y fitting and tie the drain into the garbage disposal or dishwasher? It would save on cutting and glueing
Nothing wrong with drinking the carbon.
I’ll bet she cleaned out his pipe afterwards…
Instead of cutting the drain pipe, can I just have the discharge tube point into a bucket? Then I can reuse the water for plants outside.
You can do that, but you would need a biggg bucket depending on how much waste water is produced by your system.
Thats the good news living in Germany, our water from the line is verry good, way better than normal bottled water. So if you have good water lines in your home you dont need any water filter at alll :-)
Can I get it for the whole house?
Justin Ansako no but you can get a water softener and a carbon filter installed for your whole house.
Hold the rust as well, but make it a dirty glass.
Didn't even need to bleed the air out. Or sterilize
2 gallons lost for every 1 gallon to drink….
Can we use that water something else?
Hmmmm aren’t you supposed to pressure charge the tank to approximate 5 to 10 psi
All that hard work with push connections and special “tee” fittings the job still gets screwed up during the opening of the valve!!
Poor Roger got a boo boo on his finger in this install. D:
You know they’re old school if they use purple primer
I like purple primer because it reassures people that the joints where done correctly, purple primer did not become popular until the 80s so people used orange and clear primer before then.
If your wife is still addicted to buying water bottles, do a blind water test. Give her 4 ounces of name brand water, filtered water, and regular tap water and see if she can taste the difference between the 3
Pretty sure you’re supposed to let the first tank fill up and dump it before drinking.
My problem with these is that usually, including this video, it implies that the water coming out of this is good healthy water. But it's not, this is a simple solution for when you have a serious issue with your water. But the water coming out is not good, it's pure. Water is a major source of vital minerals and metals, and should ideally not be "pure", if it is then you need to get them from other sources.
True in my applications I add an alkaline filter, ro water is also of low ph,or acidic.
True
Air gap style faucets are the worst. I'll never use them!
In the water we drink it has minerals that our body needs... RO water is a water filtration that filters everything out except water molecules the higher the rejection rate the better the quality of the water... RO water is pure h2o... but a water filtration that uses granulated carbon is great cause it absorbs cloramines & chlorine, but add a sediment/ultra filter & you have a perfect water system that removes all of the bads but youre drinking all the goods in what water gives
Not quite a fan of how much water is wasted for the sake of getting 'cleaner' water.
I don't think this will work with well or septic.
Why? I have both and no problems with my RO unit.
well and septic is when you want an RO system, space claim is the bigger issue
WHAT??? No plumbers putty?
the water pressure is god awful
Pressure is dependent on the storage tank pressure bladder. They're not meant for use past the tank capacity which is usually 1-2 gallons depending on what you buy. The biggest concern is the water waste.
Well...after you install the R/O system you need to let it run for about 5 minutes to clear out the filters and then allow the system to charge the accumulator tank.
I've put 50 GPD systems in my homes and never had an issue with low pressure.
He also didn't open the valve all the way... hopefully he opened it all the way and we just didn't see that in the video.
@@ChefBoyareB been a plumber for over 10 years i know hah
@@scallywag1716 oh i know been doing plumbing for a while
No shut off for the unit or the storage tank? Calls for disaster 😨
I think the unit shut off is in the cold water line adapter, as far as the storage tank having a shut off I have found it not really necessary, but it is welcomed. You can just turn off the whole thing at the cold water line adapter.
Rather plumb In another angle stop incase a leak happens. Without isolating water
Did he say that you're going to lose between 1-2 gallons of water to drain for every 1 gallon of clean water? That waste is criminal; or it at least should be. Remember this is a cit water that our tax dollars have already cleaned to meet the standards. unbelievable
Im assuming this is a contaminated well from road salt, otherwise the water would ve unhealthy to drink. The state of maryland cane in and did our entire house not just our sink for drinking.
You think city water is clean? I need to move where you live.
That’s how all RO systems work so imagine cities that do it on an industrial scale. Go complain about them first
All you need to do is install Watts Premier permeate pump ($67 @ Amazon), which uses no electricity to increase the output rate and pressure, as well as to decrease the water waste.
I think ro is aimed for people with well water but still that's a lot of waste.

Not a scam. It purifies water. Simple if you like bottled water this is for you
Currently I get it from in front of a grocery store.
