So, I bought one of these (version 1) the last time you did a Jackery sponsorship. I got it to use as a backup for my CPAP machine, and it works just fine. I went ahead and tested it when I first got it - full humidification and my normal pressure settings. (Yes, my CPAP machine is a real electricity hog.) It lasted for two nights, which is much better than my original backup, which only lasted for 20 minutes... The Jackery is still going almost two years later.
Can you set up the jackery :in the most farmer John way" to power the house "be semi off grid". When the jackery is low on juice, auto switch to grid power. Basically consume all of your solar instead of the traditional way of selling solar back to power company.
I think a Pond liner is a better option for addressing the leak. You could just try some 5mil slab vapor barrier plastic if the owner doesn't want to spend a lot of money on a pond liner. Amazon has a 40x40 45mil pond liner for about $400 USD. If its just leak in a small area you probably don't need a huge linear the entire size of the pond. Perhaps go with a cheap 5 mil vapor barrier placed in the deep end just to see if that fixes the issue. If it does, then buy a more durable pond liner.
(Retired Firefighter) When we hook up to a fire hydrant, we use 5” diameter hose. When we first started using this hose the factory and sale rep., told us an little interesting bit of information on water hammer. 1000 feet of 5” hose, flowing 1000 gpm, Is the equivalent of try to stop a 17,000 pound truck doing 35 mph. He shared an anecdote about a fire department that was doing testing of their new hose with the above configuration. They we’re flowing 1000 gpm and the order came to shut down. The pump operator reached over and pulled the quarter turn valve shut. The water hammer moved the fire engine sideway 5 feet and broke the pump on the engine off its mounts. As well as destroying almost a half mile of water main. It also caused the hydrant they were hooked to lift up and lean. That is why all Large diameter intake valve on fire apparatus are gate valves now. This was in the early eighties.
Finally an explanation of how a ram pump works that I understand. If you never achieved anything else with your channel you have made it all worth while 😊🇬🇧
Jon, the light bulb finallly lit up for me when you began with an explanation and demos of water hammer. I have known about water hammer and its effects in fluid dynamics, but applying this principle to ram pumps made it click for me. You are a talented shop teacher, and I am blessed to be your student!
And the whole thing is just like a step-up DC-DC converter) Flowing mass of water is replaced by a coil, valves are diodes, and the switch is integrated into a chip)
There are 2 content creators who have mentioned a desire to use a ram pump.... one guy (Wild We Roam) just LOVES to develop springs to supply his household water.... and he's in upstate NY; the other guy (This Off Grid Life) is in Canada where his water supply is significantly lower than his home. He uses solar electricity to pump the water.... but has a real problem in the cold weather months. So I just went and told them both about THIS video - I bet this will help a LOT of people trying to accomplish such a task. I keep wondering why we haven't made good use of what they call a water battery.... as China has built several mega water batteries in order to supply electricity in a "green" way. Anyhow... again - THANK YOU for sharing this.
48 seconds in and thank you so much this is something i have been wanting for a long time a good breakdown of a ram pump, always forget to look it up and now since i come back here weekly i do not have to remember to look it up.
I've seen many ram pump explanation/demo videos and this is by far one of the best. Starting from basic water hammer with a single manual valve and then building up to a full ram pump piece by piece was genius. Makes it very intuitive to understand the operating principle. Great video!
Just the first few minutes of this video demystified the entire process. Thanks! Hell, I am going to build one even though I don’t even need one. I just love to learn things.
Virginia Worker, This is Hoosier Farmboy. I live far away from Indiana, and I never comment...but, thanks for one of the best practical physics lessons I have ever seen. My teenage children adored your approach and clarity. Merry Xmas.
I build my own pretty large diameter based water system on my farm for mainly irrigation with ball valves. I put in pressure tanks with membranes and kompressed air because I was sure that closing the valve in an instant would produce pretty substantial pressure spikes and also to protect the well pump from turning on too often. First test of closing the valve instantly on the far end of the system with a pressure gauge, showed yhe water hammer nicely and you can also feel the water oscillating in the pipe. I am glad I put in the tanks. I did not realize that these pressure spikes could actually be used for something like a pump. The check valves do not like sand and such, it blocks them and stops them from working. Filters help. Thanks for your great explanation.
Used to. Technology, wood shop, auto shop, and various supporting classes. I took them in the mid 90's, before they started to phase out. I even thought it strange as a young man. Why? Was it simply a lack of demand? I don't think so. The classes were full. Forces one to ponder.
17:44 that is really cool, you can actually see the rebound as it sucks air into the system as the pressure suddenly drops off before the rebound comes back to the check valve
Oh WOW!! Ever since I heard about the "ram pump" - I've been trying to figure out how it works... and I've been wanting to see a technical drawing or see one in action. This is PERFECT!! Thank you for sharing this.
I’ve known about ram pumps for years, but I never really knew how they worked. Your description made it very easy to finally understand these clever little contraptions. Thanks!
Not first, but here after just 7 minutes! Really amazing explainer! It's always so cool to see purely mechanical devices and how the same logic we're more familiar with in electronics applies to them
I'm sure people have told you before, you need to teach practical engineering at a local high school or college. Your explanation was excellent and engaging. Engineering is about problem-solving in the real world, this sort of thing brings theory and practice together beautifully in a way that even non-academic kids can understand.. This is how you engage kids to follow vocational training rather than academic pursuits. I am happy with the academic approach but also understand that in the end, someone needs to get their hands dirty making or fixing it!! There is a real satisfaction to be gained from having a product that does something at the end of a process purely from the effort you have put in. You started with nothing, now you have something!
LED on Backwards check valve: It would be neat if your farmer friend could look out and see that the Ram Pump was operating. By installing a micro switch that would be operated from backward check valve shaft one could connect a LED and small battery (optional solar charger) that would pulse with the operation of the pump and could be seen from your customers house confirming Pump operation.
Your step-by-step build-up of the concepts relevant to the ram pump is the best I have seen. That made it very easy to visualize and understand how it works. Once you get the pond sealed, I have another idea. Dam up the creep to make a nice pool and get a gas powered pump with about a 2 or 3 inch line. That will probably move more water in 30 minutes than the ram pump does in a month. Just sayin'!
Thanks, now I can understand how the VERY old ram pumps my Dad would find, in the goose chases for antique engines and things, and we found a couple VERY LARGE old ones from around the 1800,s. They would use them on farms to fill stock tanks without using a gasoline engine or a windmill later electric, and in some cases have running water in the house!! Mom didnt sell a couple of them, one has a LARGE air chamber on it to, no doubt it would pump a LOT of water , Just a idea, as a kid we had a old creek next to a abandoned rail line ,we invented the mountain bikes term before that was a thing in the 60,s,26"tires and ripped the fenders off of them, and the old rail bed was our highway, and a leaking pond they built in rock and clay. Neighbors parents got about 12 to 20 hogs and fenced it in, the big pond sealed up in about a year, from their feet and wallowing around in it, of course you would have to let it get almost dry, at 1st ,as it got deeper the hogs will pack the banks further up as water level rises , might try that to save some time ,fuel, and hassle and enjoy pork steaks , sausage and hams to. LOL
Thanks for the amazing explanation. There are still remnants of a ram pump at Red Hill in a creek by our gardens. Now I finally understand how it works 😂
I've played with Ram pumps most of my life and I discovered something interesting a larger intake pipe makes all the difference in the world ! a 3" pvc pipe( even if the flow into it is small) going into the 2" ram pump would probably fill that pond over night ! most people will say well I don't have that much water flow ! but you can adjust how much waste water you get so you only use as little as you need.... the check valve for the waste gate is the key to a good ram pump. although the design you used is easy to build..... come on Jon you can do better than that ! make one out of stainless steel and have the tension infinitely adjustable ! it is best if you keep the waste check valve horizontal it makes a big difference ! I made a 3" ram pump for my father-in-law's year round creek but sadly alzheimer's struck before I got a chance to install it for him. the air chamber is more important than you eluded to.... it not only smoothes out the flow to a certain extent (not completely)but also provides a place for pressurized water. so the bigger the better on the air chamber it will fill about 1/2 way with water...that is normal with your waste gate horizontal and a threaded rod and spring to adjust the back pressure your in like flynn ! the problem with the waste gate is it has to be as friction-less as possible so a flapper valve may be the answer where you can still use gravity( weight ) to adjust the back pressure.but make it out of brass or stainless as steel pipe won't last a year ! i made mine completely from PVC and some fancy PVC welding with a soldering iron ! Now you can adjust the flow by the speed you adjust the flapper valve opening the slower you adjust it to the more volume but the bigger chance you have of it locking up, the faster you have it going the less it pumps but also wastes less water. so even if you have a large intake and big ram pump you can adjust it down to accommodate the flow available....in theory at least. a ram pump does waste alot of water.... about as much as it pumps so if your creek is small in the summer you may have to turn it off. a 1" ram pump with the same 1" input with a good head will pump a great deal of water over 24hrs..... will it keep up with the leaky pond ? who knows, probably not as ponds can leak more water than they will hold some times ! your idea of digging it deeper and spreading clay is a great idea.... but the dirt/clay you have there is not good clay ! you need good clay ! or a plastic liner buried !!!
Jon, if that pond had a bunch of trees around it it would fill due to the leaves falling in and covering the bottom but it doesn't. I think your summer plan is a good idea, can't wait.🚜
Dude, you could teach water hammer at Naval Nuclear Power School (where I learned about WH). How do freezing temperatures affect the ram pump's performance, or is it a 'non-winter' season only system?
It can't handle freezing, but it does have some resistance to it because everything is moving. If it continues to move it could probably work at some moderate level under the freezing point. Hard to say what temp that would be.
that's really cool! makes me wanna go out and build one right now hahaha! except its winter :P very cool old technology! thanks for breaking this down and explaining how it works :)
Best explanation of a ram pump I’ve seen yet. Thank you for explaining the water hammer effect. Until now I never really got it. Turns out , it’s not magic. Thanks John.
Fascinating topic, Jon. Thanks very much for posting this video. I'd heard about ram pumps in the past, but hadn't given them much thought. Some clever engineering went into those. 🤓 👍 Related to water hammer, years ago, I worked at a company that had a wash facility for cleaning tanker trailers after product deliveries. They ran some pretty impressive power washer spray guns connected to water feed pipes in the ceiling, and when they were working, and I was doing my IT work on their systems, I'd occasionally hear a bang overhead (like someone hitting a pipe with a hammer). I asked about it and was told about water hammer in the pipes. They said it was nothing to worry about because the system was designed and built to handle multiple times the over-pressures generated by the water hammer. Still, I always thought they should have one of those air chambers like you showed (or like the expansion tank on my house water heater), to absorb the water hammer and minimize the wear and tear on the pipe feed system. 🤷
Great job on the workings of ram pumps. If you are going to excavate and compact the pond base, I would recommend adding Bentonite. Bentonite is a natural clay material that swells when wet, creating an impermeable barrier. It is widely used for sealing ponds, lagoons, and other water retention systems.
Oh that looks so cold, basking in heat down under here in New Zealand. Great explanation on how the pump system works and the simplicity of it is remarkable. Have a merry Christmas Jon, Jen and the family.
Hey Jon, im from Germany and here we like to use Sodium Bentonite to seal leaking ponds. Should be pretty common in the US as well, because you happen to sit on most of the worlds resources of bentonite as far as i know 😄
Using a creek for feeding you might want to check out "clapper boxes". Essentially the same principle but designed differently for the different situations.
9:00 The two gauges very likely have different time constants. For example, the 2nd one seems to be oil-filled. If the measurement is damped, then it will tend to average over a longer period and therefore give a lower peak reading.
Great demonstration and explanation on the water hammer. Thank you very much. They used one on an episode of Moonshiners but never explained how it worked,
Look up "Ha Ha Tonka water tower" in Camdenton Missouri. Ram pump moves water almost 300 feet up from spring. Never could understand their drawing on site. This was early 1900s. Thanks for your explanation sir.
A similar effect is used on engine air intake tracts. When the air intake valve shuts in the cylinder, the high speed column of air intake charge, and actually abruptly comes to a stop. This creates a reflected pulse wave that travels back up the air intake tract and slams into the plenum chamber that feeds the individual intake runners. That second reflected pulse wave, can precisely coincide with the next air charge "breath" as the air intake valve opens. Those two coinciding events helps push more intake charge into the cylinder. Some engines, can get almost 100% volumetric efficiency, almost like free supercharging. Only draw back, the effect only reaches its best efficiency at a specific rpm, unless the air intact tract length can change length (variable). So fluid hammer has its applications.
Did you ever want to be or were you a teacher? Your explanations and videos are so informative. And like others have said you keep our attention and I watch your videos from start to finish. Thank you so much for posting!!
Hi John, you have just spoken in simple terms of how water hammers and a ram pump work. Yours has to be the best described and illustrated I have ever seen and you couldn't of made it any simpler. Do I sense that Large Marge will be dipping her toes in the water to move some clay?

This is absolutely the best description I have seen for how a water ram pump works. Thank you.
Thank you it is really great design.

One of the few creators who keeps my attention from start to the finish of their videos. Keep up the great work!
This is the best explanation of a ram pump I have ever seen. This is what I am going to use whenever anyone asks me about this from now on.
Playing in sand in creek is the life, "Honey I am going to do adult work now"
Dozer wanted to help also.
Really great explanations on how a ram pump works!
As someone who has never heard of a ram pump I found your explanation of its function extremely understandable! Thank you!
Thank you for teaching... I learned something!
19:05 is a great example of how capacitors work in electrical systems

Jon is my favourite seal farmer.

I build my own pretty large diameter based water system on my farm for mainly irrigation with ball valves. I put in pressure tanks with membranes and kompressed air because I was sure that closing the valve in an instant would produce pretty substantial pressure spikes and also to protect the well pump from turning on too often. First test of closing the valve instantly on the far end of the system with a pressure gauge, showed yhe water hammer nicely and you can also feel the water oscillating in the pipe.

If only more subjects in schools were taught like this.
Used to.
Technology, wood shop, auto shop, and various supporting classes. I took them in the mid 90's, before they started to phase out. I even thought it strange as a young man.
Why? Was it simply a lack of demand? I don't think so. The classes were full.
Forces one to ponder.
17:44 that is really cool, you can actually see the rebound as it sucks air into the system as the pressure suddenly drops off before the rebound comes back to the check valve

BRILLIANT EXPLANATION!

8:50 The 15 psi gauge is filled with glicerine (afaik) that dampens the movement of the gauge. That is why the spike seems lower.
Good point.
My father's friend had a ram pump on the river in 1967. I understood them better after designing electronic boost converters 20 years later.
Ram pumps are awesome!
Beautiful video - well explained, and cool to see the end result and also the struggles.

Wow, ive been puzzled by ram pumps for years, thanks to you I now fully understand the principle. A great explanation and demonstration. Thankyou .
good info on how a ram pump works, maybe the best that I have seen.
Brilliant - I love these things. Cheers.
YESS!! Let the weekend begin!! And a very interesting topic with which I am not terribly familiar!
Learned something new today! Thanks Jon!
Thanks for the amazing explanation. There are still remnants of a ram pump at Red Hill in a creek by our gardens. Now I finally understand how it works 😂
I have learned so much from your channel. And even the sponsored bits of your videos are interesting to watch. Hat off for what you do!
Thanks Jon. Merry Christmas to you & yours. Take care & stay safe.
I learned something today. Thank you for the clear explanation.
As a plumber water hammers are the bane of my life.
Why did you run out of water nails?😳
Thanks for the pond update. A very interesting problem there! We have faith in you! 🙂
I've played with Ram pumps most of my life and I discovered something interesting a larger intake pipe makes all the difference in the world ! a 3" pvc pipe( even if the flow into it is small) going into the 2" ram pump would probably fill that pond over night !
most people will say well I don't have that much water flow ! but you can adjust how much waste water you get so you only use as little as you need.... the check valve for the waste gate is the key to a good ram pump. although the design you used is easy to build..... come on Jon you can do better than that ! make one out of stainless steel and have the tension infinitely adjustable !
it is best if you keep the waste check valve horizontal it makes a big difference ! I made a 3" ram pump for my father-in-law's year round creek but sadly alzheimer's struck before I got a chance to install it for him. the air chamber is more important than you eluded to.... it not only smoothes out the flow to a certain extent (not completely)but also provides a place for pressurized water.
so the bigger the better on the air chamber it will fill about 1/2 way with water...that is normal
with your waste gate horizontal and a threaded rod and spring to adjust the back pressure your in like flynn !
the problem with the waste gate is it has to be as friction-less as possible so a flapper valve may be the answer where you can still use gravity( weight ) to adjust the back pressure.but make it out of brass or stainless as steel pipe won't last a year ! i made mine completely from PVC and some fancy PVC welding with a soldering iron !
Now you can adjust the flow by the speed you adjust the flapper valve opening the slower you adjust it to the more volume but the bigger chance you have of it locking up, the faster you have it going the less it pumps but also wastes less water.
so even if you have a large intake and big ram pump you can adjust it down to accommodate the flow available....in theory at least. a ram pump does waste alot of water.... about as much as it pumps so if your creek is small in the summer you may have to turn it off.
a 1" ram pump with the same 1" input with a good head will pump a great deal of water over 24hrs.....
will it keep up with the leaky pond ? who knows, probably not as ponds can leak more water than they will hold some times !
your idea of digging it deeper and spreading clay is a great idea.... but the dirt/clay you have there is not good clay ! you need good clay ! or a plastic liner buried !!!
That dammed pond!
I love this more educational style of content. Reminds me of the earlier days of the chanel. I learned a lot from this video, thank you!
Enjoy your videos very much. Keep up the good work.
Jon, if that pond had a bunch of trees around it it would fill due to the leaves falling in and covering the bottom but it doesn't. I think your summer plan is a good idea, can't wait.🚜

What a great education finally understand hammer pump Thanks 👏👍
Practical Engineering has a great video about water hammers.
Thanks for the video, helps a lot!
Best explanation of a ram pump I’ve seen yet. Thank you for explaining the water hammer effect. Until now I never really got it. Turns out , it’s not magic. Thanks John.
its kind of works like a voltage doubler in electronics, where the diode is your pressure valve.
and inductance instead a water flow)
thanks for that explanation. it was great
Too bad Dodge wouldn't sponsor your Ram Pump video...oh well...life goes on

Still, I always thought they should have one of those air chambers like you showed (or like the expansion tank on my house water heater), to absorb the water hammer and minimize the wear and tear on the pipe feed system. 🤷
Great job on the workings of ram pumps. If you are going to excavate and compact the pond base, I would recommend adding Bentonite. Bentonite is a natural clay material that swells when wet, creating an impermeable barrier. It is widely used for sealing ponds, lagoons, and other water retention systems.
Great video as always. ❤
Oh that looks so cold, basking in heat down under here in New Zealand. Great explanation on how the pump system works and the simplicity of it is remarkable. Have a merry Christmas Jon, Jen and the family.
Great explanation. Love your videos mate NZ/UK
Wow. I learned something new again. I’m impressed cause often I know everything but this is a new one for me! Love this channel!!
Great video !!!! Love your stuff..
Great content! Even the ad!
Hey Jon, im from Germany and here we like to use Sodium Bentonite to seal leaking ponds. Should be pretty common in the US as well, because you happen to sit on most of the worlds resources of bentonite as far as i know 😄

Seal, seal, seal, seal, seal, seal, seal!
14:36 "how high`s the water mama? She said it`s five feet high and rising"
You blinded me with science
Thanks for this !!! 🎄🎄🎄 Merry Christmas Everyone ☃️☃️☃️
Great video!
If you keep having debris issues with that style check valve give the gate style check valves a try
excellent demonstration of natural physics, next look at Trompe, water powered air compressor.
Jon sometimes you just have to get your rock off...of the check valve. Great video thumbs up.
Using a creek for feeding you might want to check out "clapper boxes". Essentially the same principle but designed differently for the different situations.
Thanks for explaining ramp pump for me so i understod it :=)
9:00 The two gauges very likely have different time constants. For example, the 2nd one seems to be oil-filled. If the measurement is damped, then it will tend to average over a longer period and therefore give a lower peak reading.
Great demonstration and explanation on the water hammer. Thank you very much. They used one on an episode of Moonshiners but never explained how it worked,
Maybe a poly liner for the pond? Another thoughtful video, good on you! 😊
Look up "Ha Ha Tonka water tower" in Camdenton Missouri. Ram pump moves water almost 300 feet up from spring. Never could understand their drawing on site. This was early 1900s. Thanks for your explanation sir.
A similar effect is used on engine air intake tracts. When the air intake valve shuts in the cylinder, the high speed column of air intake charge, and actually abruptly comes to a stop. This creates a reflected pulse wave that travels back up the air intake tract and slams into the plenum chamber that feeds the individual intake runners. That second reflected pulse wave, can precisely coincide with the next air charge "breath" as the air intake valve opens. Those two coinciding events helps push more intake charge into the cylinder. Some engines, can get almost 100% volumetric efficiency, almost like free supercharging. Only draw back, the effect only reaches its best efficiency at a specific rpm, unless the air intact tract length can change length (variable). So fluid hammer has its applications.
Did you ever want to be or were you a teacher? Your explanations and videos are so informative. And like others have said you keep our attention and I watch your videos from start to finish. Thank you so much for posting!!
9:00 You had more than 9 PSI - it's just the spike in pressure is faster than the gauge can fully react.
Very good video I like watching your videos I find them interesting 🤔 thanks
Hi John, you have just spoken in simple terms of how water hammers and a ram pump work. Yours has to be the best described and illustrated I have ever seen and you couldn't of made it any simpler.
Do I sense that Large Marge will be dipping her toes in the water to move some clay?
Please sir, may I have another?
That's cool.
Tkzz for sharing,.,.,.,peace
Interesting to see that it is still leaking even thought you did that leak treatment.
