I've been down the ram pump rabbit hole over the last few days, and I can't help but wonder why (short of the cost), a small commercially built pressure tank wouldn't work in place of inner tubes and tennis balls and pool noodles.. They're built specifically with a diaphragm to do exactly what you're doing, and they're safe for potable water.. I can't imagine what water tastes like after it's run past a trio of tennis balls... :) Regardless, thanks so much for introducing me to these pumps. I've been contemplating ways to move water over some pretty long distances on my property, and this will definitely do the trick!

[@adubs.]

you should try adding a bladder type expansion tank to this system so you can pre charge your tank with above atmospheric pressures.

[@romar1581]

To drill a tiny hole, 1/32 in, just below the check valve under the pressure tank would remedy the air-loss in the pressure tank entirely. I know it is somewhat counter--intuitive, but it works. You will see water squirting out, but every time, just before the valve acts, it sucks in a small amount of air into the pipe. My grandpa used an old hydraulic ram pump some 40 years ago and he explained that this little hole was crucial to the function, otherwise the pressure tank would lose its air and the pumping would stop.

[@harrymu148]

[@CletoCelto]

When you ll be amazon

[@arfyness]

The water level went down because the air volume increased. I bet tiny bubbles in the standpipe introduced more air into the chamber. You had delivery shut off, so they couldn't escape that way. The pressure seemed about the same as when it had more water volume, so that backs up that there had to be more total air introduced.

[@mikeh6286]

Yeah, it reminded me of how they used to produce compressed air for mining equipment 100+ years ago.

[@CR3W1SH03S]

My guess is that the water level went down without losing pressure (as noted when you opened the drain valve) because dissolved air in the water escaped and filled the top of the pressure tank. There is a lot of air in water.

[@PlayNowWorkLater]

To actually see what’s going on inside through the clear PVC pipe is amazing to watch

[@michaelfixedsys7463]

ram pumps: the hydraulic boost converter.

[@teravolt1195]

Boosts aren't as wasteful though, but yeah, the concept is there. It's always amazed me how efficient boosts are though, you're shorting the supply. But when you think about it more, as you're modulating for how long it happens and so it averages out the Cu and Fe losses, which come way down to a pretty small level. Doesn't work for water haha.

[@Nebsgame]

You could say it ramps up the pressure

[@myvoiceismysword5484]

This is powerfully done. I will use your invention to power my house for free. Thank you

[@myvoiceismysword5484]

Bro the giza pyramids use the river to have made. Giant ram pump

[@Databyter]

I think you should consider putting a shrader valve on the top cap of your pressure tank, you could incorporate a gauge in the same plumbing to check air pressure.. You could release the pressure when experimenting to make it less stressful and wearing on the ball balve. Also, you could experiment with injecting air pressure into the pressure tank besides the amount that is passively there at the start by the size and shape of the tank itself. You could add air volume with a bicycle pump. Not that it is needed, but in the spirit of experimentation, it would give you the effective results of a longer or wider pressure tank, while keeping the size as it is. This might be useful for instalations that do not have the vertical room for the tall riser. Just some random thoughts. Great video, oh, and Ive asked before, but havent heard back WHY USE PRESSURE TANK FILLER AT ALL? It seems unnecessary to me. What is the advantage. The air is already there. Databyter

[@TheFarmacySeedsNetwork]

Well that settles that. Thanks! Glad to have a visual.. that explains why the tennis balls didn't do very well. Anything that doesn't hold up the "volume area" for the PC.. effectively isn't there as air pressure space. Keep up the great tests Seth! When you read deep into ram pump design.. all the old school stuff says use a snifter valve and infuse air into the pc with that. I have been wanting to for a while.. but that hole size is critical. I have some ideas though. cheers!

[@LandtoHouse]

Yes the hole size is very important! the couple times I have tried did not go so well. I have a small valve used in a Cpap machine. I wonder if that will work? It would allow some water out but I am not sure that it would allow enough air to enter the pump to replenish what is lost. This test is on the list for the summer if I can find time to make it.

[@LeanPocketDiet]

The increased air is from the tennis balls expelling there pressure. Tennis balls come pressurized. This is why they are in an air tight can.

[@MrAndrewbrake]

There was far more air in that pressure tank than was ever in the balls, and the balls still had pressure when taken out. Most likely explanation is bubbles in the water being pushed into the pressure tank. The displaced water in the pressure tank would have been escaping back out the one way valve (you will always lose some water as the valve closes)

[@Jameswrightdavid]

No, it is from entrained water. The early air compressors worked in a similar way. They're known as Trompes There is a great video on it here: kzbin.info/www/bejne/q6fJYZ96at2tfpI

[@FusionStream]

Maybe he could use that trompe to periodically keep the air topped up instead of using a bladder.

[@0Sunny_Ray0]

There is no contribution of the tennis ball about that theory. The rule of the tennis ball rule is only to increase the water pressure of the tank.

[@toasterbath1395]

Big Jon no the reason the tennis balls flaten is because the pressure is not equal on both sides of the ball

[@marcusmagee4481]

Water is being displaced by new air that is coming in with your supply water(micro bubbles). Small amounts over time will displace the water and give you a better air spring.

[@Seriouslydave]

Huh good point, if this were drinking water what would your thoughts be on compressed stale air?

[@Daniel-if2sx]

Little late but have you tried a equalizer cylinder? It's a hydraulic cylinder with a loose piston in it and gets pressurized on both sides thus creating a suppression reservoir to supplement volume and not starve a system. Sold as a race engine preludes but doesn't matter what you use on either side of piston ie: oil,air,coolant

[@davidperry4013]

The water level coming down during the experiment could be due to air entering the system

[@alexreeve]

thats what happens i think. you could add a manual or automatic bleeder valve to get rid of the air.

[@peternunn7104]

the air pressure in the tube is forcing the ball down against the bottom fitting creating a seal, preventing the water from entering the tube, you can see the black mark on the ball when you remove it.

[@donaldsmith3048]

air got in the water coming down the supply pipe! Water often has some air in it. Having worked with wells, I have had that trouble before. I know you would not think well water could have air in it.

[@SlayingBB324]

Nothing beats good old Air. Anything you use. Tennis balls, Inner tubes, Pool noodles all have air as the main displacement component, Unless the the object is solid pocket less material. If anything you use has drag that is grater then and compression rate that is lower then air it only lowers your efficiency. The more the object can compress and the faster it can be compressed and expanded the more efficient your system is anything that takes up space that cant be compressed or expanded causes you to lose volume that could have been used for compression and expansion. A taller pipe is a better if you want more pressure. If you want to test this yourself I would strongly recommend getting a pressure gauge that shows you highest pressure and current pressure. Watch the needle bounce between its low high and common psi. The more deflection and higher pressure the gauge has the more efficient your system is.

[@warreneast1144]

The answer to the accumulation of air in the ballast tube is; Air dissolved in the water is released into the ballast chamber during the pulsing action (Pressure cycles) and cannot escape thus forcing the water out the bottom.

[@gregoriocinco921]

The water level did went back down due to the accummulation of air in the tank. You see, there are tiny air bubbles that go with the water or air dissolved in the water. I predicted as I watched your video that the moment you open the drain valve, there will be too much air that will come out, and, obviously there was! Thanks for sharing your wonderful video! God bless!

[@drmarine1771]

I've been trying diferent things inside the tank. Yours is great can see exactly what's happening. Great effort ...

[@LandtoHouse]

Thank you. It sure is fun seeing what's happening inside the tank because by the time you relieve the pressure to see how well something fared it's probably gone back to its original shape

[@Skydiverjoe2871]

@8:30 i wonder if its building air inside because of small air bubbles feeding the pump from upstream, the air bubbles are being compressed and entering the clear tube where it is unable to escape

[@asterix2ksi]

Came here to say this. Another guy used a bucket upstream to remove air from his pump feed line. Also reduced silt.

[@LandtoHouse]

Yes air stops a pump really fast.

[@LandtoHouse]

I also like the bucket intake method. It reduces silt and provides an air free source.

[@Jameswrightdavid]

@@LandtoHouse It's like a Trompe! No moving parts air compressor? Heres one here: kzbin.info/www/bejne/q6fJYZ96at2tfpI Next project maybe? Free shop air?

[@MrTrevorkemp]

And you can press air. It becomes hot. The reason that when the feed valve that what's the water go to where you're pumping it to? Keeps the water level up in the pressure tank is because you have a fresh flow of cool water and the cool water is absorbing the heat from the pressurized air. Keeping it cool with that valve off but still building pressure in the rest of the system. The air eventually gets hot enough that it builds enough air pressure that it pushes the water level down. Plus there was probably a very very slight leak and one of those things, but not nearly enough flow to allow the water in the pressure tank to pull the heat off of the air in the pressure tank so the reason you actually saw the water level go down in the pressure tank is because you were no longer able to dissipate the heat built up in the pressure rised air with having a good flow of water warm and cold going into and leaving the pressure tank that's why when the feed valve is open the pressure tank builds up to a certain level and stays at about that specific level and when you close it but leaves the ramp pump running. After a period of time the pressure tank will be full of water but then eventually it will look like it's empty and has no water. Realistically another thing that was probably happening is the air pressure built up so much because it got so hot that even though the valve was properly cycling it was probably feeding water from the pressure tank and water from the pressure tank since there was not enough flow of freshwater. Going through the pressure tank to pull the heat off of the pressed air in the pressure tank actually caused the pressure tank to back feed through the valve which is a completely possible and plausible reason that after 2 days the pressure tank was almost empty of water because the air had reached such a high temperature and high pressure that it had more pressure than the ramp pump could produce except for keeping a tiny bit of water in the pressure tank again with the feed valve open feeding water to wear. You are trying to get water too using the pump. There is enough flow of fresh water into the pressure tank that it was pulling the heat off of the compressed air in the pressure tank without having enough flow of fresh cool water. In there, the pressure was able to build up. Most likely the water got warm in the pressure tank as well and the water evaporated into steam in that case, which is why you still had a full pressure tank, but it was a combination of compressed air and steam at that point.

[@johncochran8497]

Considering that tennis balls are kept in a pressurized tube prior to use implies that they're permeable to air and hence over time in that application would become water logged. So they're not good for long term fill.

[@MRGF78]

The water level went back down because of the accumulated air pressure... every time the valve slams shut and then opens, it's sucking in little gulps of air... that would be something to measure... need to get your pressure gauge on it now...

[@joshoertle3779]

What we don't see, is how these things you put in there effect the actual operation. How many feet higher does this pump water? What is the benefit of one thing over the other? Why the bicycle inner tube? What pressure should the bladder be at? What if you had a way to pre-pressurize the chamber? What would that change? Let's say, with nothing in the tank, the air reaches 150psi at normal operation (totally guessing) what would we put in there that would resist that or be a better spring?

[@LandtoHouse]

I'm thinking about making a test with all of these and measuring the flow rate at the top to see if there's much of a difference.

[@ericroot8475]

fresh tennis balls are pressurized to 27 psi (1.8 bar), that's why they come in a pressurized can. 7:08 you can see that the tennis balls are still crushed, so your pressure tank is working properly. the lack of water in the tank is due to air pressure forcing the water back through the check valve. likely the air built up in there over the course of two nights when it was cool, then when the sunlight hit it the air expansion overpowered the waste valve (so the kinetic energy from the ram pipe gets soaked up just from trying to pop the check valve open, which allows the motion of the check valve to actually pump the water in reverse). it would have been interesting to see how much higher the pressure was when you turned it on than it is normally. 8:00 when you opened the delivery valve the compressed air in the pressure tank started pushing all the water in the delivery hose uphill replacing the water in the hose with air, which is why all the water drained out of the pressure tank right away. if you'd allowed it to play out, the air left in the pressure tank would have cooled off quickly (reducing the volume) because of the rapid decompression and the introduction of cold water. all the extra air would have eventually escaped out of the delivery hose as it does in a bladderless tank. you'd have had a spluttery feed for a little while, but I'd guess it would even out after just a few minutes. if you did this decompression process gradually (by burping the delivery valve), when you finished, your pump would be running at just about max output temporarily. EDIT: It's also worth noting that air expansion is how bombs work. If your materials aren't up to the task, that pressure tank could definitely explode. Don't get blinded by shrapnel, or worse.

[@ericroot8475]

look at the condensation on the pressure tank at 6:08 vs 7:08. the water in the tank was actually warm (I imagine from a combination of sunlight and compression) when you observed the weird behavior.

[@ericroot8475]

I must say, it'd never be this clear if you hadn't had the idea of using a transparent pressure tank. very cool. thanks :)

[@CookingwithYarda]

First time I've heard about Ram Pump !! Thanks for sharing ;-)

[@LandtoHouse]

Nice! There are over 100 video tests and installs for ram pumps on the channel.

[@Jameswrightdavid]

The reason there was more air in the tube is because of entrained air. This is how Trompe air compressors work. There is an excellent video on it here: kzbin.info/www/bejne/q6fJYZ96at2tfpI

[@rronmar]

Cool video. If you are trying to form a better accumulator, you could simply pre-charge the tank with air... you are looking for enough air in the tank so the water level is at about 2/3-3/4 full and it lowers down to about 1/4-1/3 at minimum pressure. Put a pressure relief valve on the output so the water you draw off passes thru it, with a spring that stops the flow at the minimum pressure to keep you from loosing the air charge. As you saw in your demo, aireated water in the input can add air volume to the accumulator, y0u will have to adjust the water level/pressure relationship occasionally...

[@davidhelfrich7150]

I’m thinking your original design with the bike tire is the best. Maybe experiment with different initial tire pressures? What is the final goal here? Cost, low maintenance, longevity, flow optimization, height of delivery, pump cycles versus water flow, gallons per cycle, gallons per hour... It seems that some of the trials could take weeks or months. 🦀

[@LandtoHouse]

You're right they could take a long time to gather information. I'm going to continue using bicycle inner tubes as the tank fill. I'm just testing these out for fun. The real goal is optimized height of delivery flow. But for consistency the bicycle inner tube is the best

[@dinosaur0073]

Interesting..!!! It is just pressure(liquid & ambient) to temperature relationship...we have study it in school..

[@andrewsmith9048]

To work properly the chamber needs some kind compressible medium to store and release the energy. Commercial ram pumps have "snifter" valves to introduce air into the presure tank on each cycle . So the more to an extent more captive air more water can be move in a cycle.

[@wolfmazter]

I've never heard of a ram pump before today and I've watched a few of your videos on them now. In my ignorance I thought of a question. If you remove the PVC pipe (the one you put the tennis balls in) and replaced it with something much bigger, like a small propane tank, would the added air volume increase water pressure at the end of the line?

[@LandtoHouse]

Thank you for watching. That's a valid question. Pressure tanks basically smooth out the output. Adding a larger tank does not increase the output. The output is based on the input head pressure. The pressure tank can only build to the pressure of the input head pressure. That's a mouthful haha

Why the water level backdown there are two hypotesis about that 1st the pipe had leck then 2nd the water pressure back- up to the check valve due to the water pressure tank level reach to the top that air dont have space anymore so the water return and find a way to exit to the check valve if when there is no leak,but if there Is a leak It will goes to the leak slowly when It reach to the maximum pressure.

[@WiliamBennettwildarbennett]

Ok might I render a suggestion that you try a 1¼" pvc pipe fitted with test plugs = to ¼ the size of your expansion tank. Reason for the test plugs, instead of caps, because they fit to the inside diameter of the pipe, not over the outside. Also think that if you were to put a Schrader valve into the top cap you could pressure the expansion tank to about 10 psi.

[@robertlane6675]

I must be the only one that smells a tube of tennis balls after I crack the seal...seriously though great video.

[@myvoiceismysword5484]

Nice work

[@billweasley1382]

If I understand the point of this, all you are trying to do is to create a barrier between the air and water. The tennis balls seemed to work fine. You just need to fill the entire tube with them. don't worry about them being crushed, because that is what is supposed to happen. It's just like when the original air gets compressed into a few inches of space at the top of the cylinder. I think that the inner tube would work better, though. You just need to place it in the cylinder first, and then inflate it as much as possible. You want to displace all of the air. Don't inflate it and then try to squeeze it in. And again, the fact that it gets crushed is fine.

[@LandtoHouse]

Yes indeed! The bike tube seems to be the clear winner for tank fill. I still have a few more things I am going to try.

Do you have the plans and parts list that's a great pump

[@calebdoner]

Depending on your water source, you could have a bit of dissolved air or microbubbles in your drive line which come out of solution in the pressure tank and increased the mass of air in your pressure tank. Alternatively, you may have a small leak after the waste valve which is allowing air into your system. One way or another, air was introduced into the pressure tank over the course of 3 days.

[@porcus123]

you cant have air before the release valve, this only works because water doesnt compress, the kinetic energy of 1kg of water falling 10 m can be used to raise 0.5kg 20 m. those air bubbles would compress and expand some of the pressure. what the guy could do is stuff a sealed balloon in the tank.

[@MoneypitHomestead]

Another great informational video!

[@TheBuffettMonkey]

Try a Styrofoam cup in the pump. The pressure will compress it down, but it will not spring back to it's original shape once the pressure is released. I have done this while scuba diving and it is a neat effect.

[@LandtoHouse]

Oh good idea. I have that hose guage that would fit there well. I think that is a good place to start reading pressure. I won't even have to take the deliver puoe off. I am not sure about building more pressure in the tank than the ram pump can make. I would need a non return valve to add that pressure.

[@MalmoeSnapphane]

Most likely your water level got down due to the order you closed the valves, you let alot of air into the delivery pipe and I think that is the reason to the drop in water level, air can be compressed not water. If you would have left it working a bit longer I think it would have settle back to normal. You should close the valves in the order of 1. Feed, 2. Delivertý and last (3) open the dump valve.

[@mdrahamatali6694]

Thanks bro

[@jllaine]

Test #1, no pressure tank just cap it, Test #2 pressure tank with no rebounder in it, just the air space, test #3 #4 #5 #6 different rebounders. Lots of designs that do not use a pressure tank to 'even' the flow through the delivery line allowing the delivery line itself to accumulate/release pressure, especially when a rubber garden hose is used. The pressure tank filled with air from the tiny bubbles of air dissolved in the water. with the delivery valve closed, a small amount of water exchanged each time the spring valve opened but most of the water sat still, allowing it to release the dissolved air. It's the same thing that makes ice cubes have that cloudy white center, air bubbles. With the delivery valve open, the water in the pressure chamber is constantly changing and absorbing air, slowly stealing the air from the pressure cylinder until there is no air gap left. That's why pressure bottles and anti-hammer valves have a seal between the wet side and the air cushion.

[@jllaine]

Also, the pressure bottle providing rebound pressure works better if the pressure bottle is 'in line' with the spring check valve, maximizing the water's inertial path into the pressure chamber before the spring valve closes.

Experiment with different gases in the inner tube, for example hydrogen, biomethane, & the gas produced through the process of gasification, helium,The Deep Voice Gas - SULFUR HEXAFLUORIDE (SF6), pure oxygen, pure carbon monoxide, if there's a difference pure carbon dioxide, are the first ones that come to my mind for you to experiment with inside an inner tube, to see if there's a difference, if one compressor is more than another, or if one leaks out more than another.

[@SmokeJensensJunction]

@land_to_house, King Cobra's Den Has good point and idea 💡 different gases compress at different rates as well as for example laytex helium balloons that have high float in them last longer than a regular latex helium balloon. So maybe adding some of that stuff I believe they call ultra-high float, or some of that green slime they use to fix and patch tires and inner tubes, (these are just the first two that come to mind) in the inner tube with the different gases that little king Cobra's Deen suggested May have even more effects and differences. I know there are other things that do a similar job, offhand I just don't know the name of any of them.

Over time the air in the pressure tank defuses into the water and the tank becomes water logged. In large commercial ram pumps there is a snifter valve that replenishes a small bit of air with each cycle. The tank fill helps to keep an air space in the tank at all times. .... The SS valves are stronger and do not wear as fast. The pump cycles around 30 million times a year and that can cause the brass to wear a ring in the flap.

Try a swimming pool noodle kids float toy. It should work.

[@LandtoHouse]

I actually have a video on that. Check out Ram pump crushes pool noodle

[@fuglyyyyy]

@@LandtoHouse I saw a video where someone drilled a small hole on one side of the valve which allowed a little air to be introduced in each pump/ram, can you do that too?

[@Rover109able]

You could drive something with that Pressure !?

[@jllaine]

Looks like it would have held 7 tennis balls, could you try that? I'd love to see you try ball pit balls.

[@corneholtzhausen8565]

Like your work man!!!!!!

[@LandtoHouse]

Thank you. The ram pump is really fun to work with. Lots more content planned for 2020... when the weather is warmer.

[@ajtyrone1072]

Very interesting job 👏

[@dougattridge4877]

What would happen if you put a few Ram pumps in series at strategically placed stages after your first output? could it increase output pressure at all? and then also maybe have one on a down hill section of the output after the first RAM Pump? just Curious

[@davebean2886]

100 videos on ram pumps !!!! Guess I'll have to allocate more time. I really like the clear pressure pipe so we can see what is going on and I saw in another of your videos that you added a pressure gauge on the pressure pipe. I think I've missed the initial video that described why you are adding more compressible medium inside the pressure pipe and the benefit that that gives. Interesting that air started to occur after a while in the pressure pipe - would that indicate that the tennis balls or bicycle tubes may not be necessary? Did you experiment with different heights and shapes for the pressure pipe? Some designs show more of a big round bulb than a pressure pipe.

[@ufuk54h1n]

The water level back down because supply pipe boost air also...

[@liacoulombe4726]

Can you leave them in there and will that make it always have crazy pressure

[@TheAlfzor]

How's the flume going ? Im gonna build one myself 😄 and awsome video on the tennis balls 👍

[@LandtoHouse]

The Flume is doing fine. Some issues with erosion underneath it. Also I highly recommend you use exterior screws. When I built it years ago I did not understand the importance on exterior screws

[@AztecWarrior69]

You should try the punch balloons like the ones in the link below but there are some that are thicker and way strong. You might even try an inflatable workout ball. Hell try a foot ball.

[@richardpeterson3753]

so two questions,is an air bladder absolutely needed,and aslo,what is the best thing to use for a air bladder material?

[@LandtoHouse]

No the bladder is not required. The pump will work without the tube in the tank. The pump will actually work without a tank. But it will hammer itself to death.

[@peterhall5110]

I like your experiments. :) keep it up! Have you tried a partially inflated rubber ballon?

[@Nthn09]

what if you add a valve that you can attach a bike pump to so you could add more air pressure seeing as air can compress where as liquids are hard to compress. Would that increase results making it push more or interfere?

[@kennyh5083]

tennis balls? Gimme a break! Use a small well pressure tank Homie!

[@LandtoHouse]

This video was a fun response to a comment.

[@conanalkaabi8051]

The opening through which intermittent water comes out... Is it possible to put a device that prevents water by pushing air instead of it, and switching between them continues?

[@jfdesignsinc.innovationsid1583]

I like this... there is a leak of some sorts in your pressure chamber however

[@LandtoHouse]

It's a fun test! The leak is happening because the delivery pipe is closed and the pump is hitting hard.

[@coryjeffreys5146]

I just found your channel and I’m intrigued. Can you tell me cause I’m an idiot what is the purpose of the inner tube?

[@LandtoHouse]

The tube is supposed to act as a bladder to prevent waterlogging.

[@dinosaur0073]

Add me in your idiot list cause I also need answer...hhhh

[@nicholasmolinaro9141]

Can you please make a list of all your parts? I’m looking to build one! Fascinating stuff!

[@The2x4]

He's got a full video with parts and very detailed how-to-build. And e-books on the website.

[@nicholasmolinaro9141]

The2x4 Figured it out on my own and built it. Works fantastic pumping water from my stream to my garden 140ft up a 40 degree embankment. Have it connected to a filter, regulator, timer, and drip lines for my veggies and flowers!

[@duanesiles1751]

I don't know why he didn't drain the mud out before sending through the delivery line

[@dillinger8534]

Run bike tube psi the same as head pressure

[@rondemarco6427]

possible you waste valve sucks a little bit of air on cycle. This would put air in the tank. My question is if the tank becomes air bound will it still pump.

[@LandtoHouse]

In large commercial pumps or the really old pumps there is a valve called a snifter valve that would replenish air with each cycle. I hope to do some more research on those this summer. ... the pump can operate with a waterlogged tank but it will hit hard and not be very efficient

[@ericwolfe8927]

I have 2 Artesian wells about 100 down hill 500 feet horizontal from my house. I am a newbie but I would like to daisy chain 2 pumps to get to the top. Start with a 2" and get it to go to a good level the drop it back doen about 20 feet into another pump. Would that work?

[@drampadreg1386]

For the tube, use co2, not air. Air will leak no matter what because it's not a single molecule and unstable, but co2 is great for bike tires. Ask anyone in the Tour De France, no air in their tires. That pump is great for gorilla gardeners too, and would eliminate the need to wear a path that can be seen from above. That would have been handy before they legalized my garden here, medicinal of course...

[@jmrb]

man thats great, men help me if i make a pump like that and i put that pump into a water tank can that pump deliver water 4 meters up?

[@0Sunny_Ray0]

My theory how to create a ramp pump with less exit of water to the check valve when the pressure back it up. I think how the design and the making of pressure valve that close the pressure tank thats the secret of it. And learned how to observe tha air level of the pressure tank its because the air Is important of it. It must have check the air level above the pressure tank. You must have a lettle bit of air inside the pressure thank to have an effective release of check valve.
