HOW TO BUILD THE BEST WASTE VALVE for your RAM PUMP

I want to say thank you for the energy you put into this video. I took inspiration from your work and thankfully, my system is working splendidly.

[@gabrielramoskarry5335]

I have to say it, I’ve been researching this ram pumps for a while. And of all the videos this ram pump design and check valve design are the most efficient. 👍🏽🙏🏽

[@paulkleinkramer5065]

I built this waste valve to replace the swing check valves we have been using on our ram pump. It works great and has increased the flow rate by a factor of 2.5 up at our cabin. Thank you Bohumir Stehlik! We have a 120 foot (about 40 meters) delivery lift from the creek bed into a 100 gallon (about 400 liters) water storage tank in the attic of our cabin. Also a mere 7 foot (about 2.3 meters) head on the 2" drive pipe. With Bohumir's waste valve design we deliver 1 liter every 70 seconds. Before I built Bohumir's designed waste valve, the constant hammering of the pump was destroying the brass seats and hinge on the 1" swing check valves regularly and I would have to replace it a couple times each season. Be advised that using leather to make the seal did not work in my case. Leather swells, gets very soft and bunches up after a few hours in the water and causes the waste valve to stick closed. I wonder if Bohumir was using Leatherette (imitation leather) or a leather like vinyl or Naugahyde? I ended up making the seal from the fabric backed rubber I cut from a knee height rubber wader boot. With the rubber side towards the brass valve seat, its been working perfectly for a few days now. Time will tell if the rubber will endure; I tried a few different kinds of leather and found that leather WILL NOT last in the water. Also, the brass reducer that I bought was a rather rough and pitted casting. I found it necessary to chuck a circular fine grit grinding wheel of the appropriate size in a drill press and use it to smooth the area inside the reducer that becomes the valve seat. I'm sure you can think of other ways to do this if necessary, but I liked the drill press because it got the job done in a few minutes.

[@BohumirStehlik]

Hello. Thanks for your message. Great, congratulations! Well, I used just over 1cm thick very hard leather. It looks it holds well and I didn't have any problems with it. It is told that leather will last much longer than rubber but it is true that leather soaks the water..

[@paulkleinkramer5065]

@@BohumirStehlik Okay, I have have made and tested several seals from different materials in your brilliant waste valve design. The winner is a seal made from vulcanized rubber I cut from a hockey puck using an appropriately sized hole saw chucked in a drill press, a twist drill the same size as the threaded rod in the waste valve and a thin bladed saw. The hockey puck seal has worked continuously for weeks and upon disassembly, shows no sign of wear and tear.

Thank you for all the work that you put into this. I just built a ram pump and modeled my waste gate valve off of your design. I will be pushing 250 ft up hill with 100 ft drop on the head pipe. I think the best thing about this valve is the tuneability. I can adjust and tune it to maximize performance for the flow and pressure that I have at my source. I think this will work great! wish me luck....

[@Costasa-u1m]

Hello Bohumir and friends, Firstly, I'd like to thank you for sending me out the PDF Shopping list and hope you enjoyed the coffee. Secondly, I'd like to share with you my results after watching all your videos and as a result, I have now 3600 litres per day running to my property. (The 2 videos in your PDF are best for great results-Cheers) *I live in Australia and we predominately use the metric measuring system. I've added some conversions here to assist others that may not use metric measurements-these are rough and near about imperial measurements * 1" inch = 25mm 1" 1/4 inch = 32mm 1" 1/2 inch = 40mm 2" inch =50mm 1 foot = 305mm 3 feet = 1000mm which equates to 1 metre 1/4 gallon = 1 Litre .. all are approximately So, once granted permission by a neighbour to have access to his natural spring on his property which strongly puts out 40Litres/minute so 58,378L/day into a nearby river. I commenced on my ram pump project/exercise to try to get some of this spring water to my property which is 600metres away. (10.5 gallons/minute so, 15,421 gallons/day...that's a lot of pure spring water being wasted per day) I now have 3600L/day to my property, by replicating exactly Bohumir's Homemade Ram Pump and Waste Valve. My inputs; Drive side of pump 6m Head(fall) to my pump 21m of 32mm rigid pvc pipe approx 30L/minute of water velocity. The waste water from the valve returns back to the spring via a small trench. Delivery side of pump 40metre lift over 200m delivery, then 400m along a small decline towards my property. Gauge reads approx 5Bar of pressure at the pump 25mm Poly Pipe x 600m to my 5000L water tank on my property. Notes; I purchased a 10Bar maximum 10L pressure tank with factory lining preset at 2Bar. I increased this to 6Bar with a bicycle hand pump. This helps with the flow rate. I also installed a wheel valve on the output, to which you can finely make adjustments/increments better, than say using a lever valve. Here you can also use this to increase lift if needed(got mine to 55metres+) though you lose output amount as a loss/result. I used a pvc check valve at approx 100m on the delivery lift length of the initial 200m of delivery length, to assist the load on the pump brass/stainless check valve. There are a lot of pressures/weight there on this valve, as Bohumir raised. Once I reached the first 200m mark and on to level ground using the 25mm poly pipe, I could've used 32mm or greater poly pipe to assist with rolling friction of water in the pipe. Then having a small decline assisted with gravity for the remaining 400metres to my property, I guessed that may just make it using 25mm all the way,to which it did.(there was evident loss of output at all 200m joins of the poly pipe towards my property-this loss would be better mitigated if larger diameter pipe was used) I will eventually replace the galvanised iron waste valve and other galvanised parts, with stainless steel as the water is very acidic here and rust will be an issue in the long term. I also know that I can tweak this set up further, and even throttle the output of water, to improve an efficiencies. If I can do it, then as Bohumir says in his ending videos " You can do it too" Thanks again Bohumir, and good luck to you all in your quests. Cheers, Costas

[@StephenfCarman]

Did I get a different parts list than everyone else? The lists I got from the Coffee after paying to support his efforts (much appreciate his efforts) were just a rehash of these videos. There were no links to help find the parts. That's what I thought I was getting when paying for it and not just the same list from the videos he'd already posted. For example, the 2 to 1 brass fitting with threaded holes in it... I can't find anything like that anywhere. Did you find that to build yours? I'm just barely getting started, and it's been really discouraging because not a single youtuber anywhere that I've found posts a parts list with links to actual parts. I've spent hours and hours and hours trying to find good parts, and I'm super discouraged at this point.

[@Costasa-u1m]

Hey Stephen, yes,you need to source the parts yourself. I found a suitable online plumbing store that provided most parts here in Australia. Some bigger hardware stores could also help, pending on where you are in the world. You also need to thread your own holes in the reducer, using a tap and die set to suit the M6 threads. Try to borrow the equipment/tools if you don't have access to any. I also managed to source my leather for the valves online (I used 2 x 4mm thick strips with outer diameter of 40mm and with a 10mm centre hole. Both strips, compressed by washers as Bohumir has suggested, on a 10mm threaded rod. Good luck and keep at it. Costas@@StephenfCarman

[@BohumirStehlik]

@@StephenfCarman Dear Stephen. First of all thank you for supporting me. Making of a ram pump needs at least some experience in DIY jobs. The shopping list and videos are international so in case of writing the links I would need to put separate links for the USA, Sri Lanka, Thailand, France etc etc etc - I don't think so people would import stuff from my homeland country (Czech Republic)... I am sure you can find the parts by searching them in Google in Your country. Or you can find almost all of the parts in shops like Bauhaus, Obi, Baumax or Hornbach (if you live in Europe). About the 2 to 1 inch brass fitting - you need to make the threaded holes for the screws by yourself.

[@familyplans3788]

love your work but a couple of ideas for you to ponder , do you have any sort of bladder in the pressure container ? i couldnt see a snifter valve so i assume you must have a bladder in the pressure container , if there isnt one then over time the pressure your getting will drop significantly , and maybe add a sleeve of copper or the like over the threaded bar as it will be sawing away at the bracket over time , like i said i love your work and i know you are open to ideas

[@BohumirStehlik]

Yes, this is a bladder tank. I don't use a sniffer but I would consider it for the future in the case of not using a bladder tank.

[@philoso377]

Thank you for sharing this wonderful valve. I also view other channel on ram pump and have gathered mixed information on waste valve hope you can enlighten us addressing this question. Have you noticed of two main streams of ram pump, Normally open versus normally shut, assuming fed by 1-2 meters of water head? I was told that the normally shut type requires manually prime until the distribution circuit has build up water volume to sustain a back pressure otherwise it will not cycle itself. Is your waste valve of normally open type and closed only by dynamic pressure? Your advice?

[@scottgraham1692]

I'll be building a ram pump for my spring soon and I found your videos. I'm really interested in building one like yours but I need to get some flow and elevation measurements first and I have some questions. I hope you can respond. 1. The 2" to 1" brass reduction...did you drill and tap those 2 holes for the bridge bolts? If so, what size drill bit did you use? 2. Is it necessary to use leather? Would rubber be okay? 3. Is the expansion tank pressurized? The ones I see in stores online are pressurized to various pressures but can be changed. Should the pressure be dropped to ZERO or maybe 5psi? 4. I'm expecting my drive pipe to be one inch but may be 3/4" if the flow is less than I expect. For a 1" or 3/4" ram pump, I'm thinking the 2" waste valve might be too big. Do you think 5/4" will be okay for 1" or 3/4" ram pump? I think that's all for now. Thanks for posting your videos and I bought you a coffee!

[@joshuam1269]

A couple of comments: 1) Use locking nuts instead of standard nuts. 2) Can you find a hard rubber washer to use instead of the leather? 3) Have you ever tried/considered using two (or even three) waste valves instead of one. (Perhaps it is not necessary since you can weight the stopper, but might be interesting to try) 4) Build a tank out of 4 inch PVC pipe with a screw plug on the top where you can place balls or a bike inner tube with air in, which can be easily maintained in the future. (Standard tanks such as the one you used will lose their air after a while, unless it was a tank with a bladder for air that you can pump up now and then... The reason why I suggested the #3 is that I saw a hydraulic ram pump in Tanzania 20 years ago that had two waste valves, (using rubber stoppers) and it was used to run sprinklers to water crops. I'm not sure if this provided more pressure or volume or both... It would be cool to see you develop one like that.

[@BohumirStehlik]

Hello, thanks for the comment. 1) Definitelly¨ 2) I don't know but leather should be more durable than rubber. 3) I don't recommend that - the two valves should be identical to work properly (to shut off in the same time). And it would be more mooving parts. 4) I am thinking to place a sniff ventil bellow the main valve.

[@gee3883]

Great pump and information, that's going to help me out big time thanks Mr.

[@StephenfCarman]

Thanks, so much for the videos! Favor to ask: I've had so much trouble actually *finding* the parts needed to build the custom valve and the the ram pump itself. Could you create a parts list with links to the parts themselves for where to get them? I've spent so much time trying to find good parts--or even the right parts (for example, the 2 to 1 brass reducer with the two threaded holes in it. I... can't find that anywhere. I would be really grateful if you or someone could create a linked shopping list. Thanks, so much!

[@savagelivemusic]

Awesome... I just sent you some coffee for the great video. One question: Does your pressure tank have a functional bladder? If so, do you have a pre-set pressure for the air part of the bladder?

[@BohumirStehlik]

Hello, thank you very much. For the last model we used a 8l pressure tank with a bladder. I pumped the primary pressure just bellow the pressure for the delivery pipe... So 17m of the delivery height = cca 1,5bar in the tank.

I've been quoted £1300 by a rampump manufacturer for the pump, then £850 for all of the ancilliaries. That's to deliver 6,300ltrs/day from a 30ltr/min spring.

[@maricelcalogmoc4785]

Nice one

[@74KU]

Only thing I would add, maybe a little high strength thread locking compound on the nuts once you have the waste valve dialed in. Those impacts will eventually loosen the nuts in time. I know it is a test setup, but if you mount that pump to some BIG rocks or pour a concrete pad and bolt to that you will loose less mechanical energy from the hammer effect to things moving and should give some performance boost, but hey 5000L/day is nothing to sniff at even so.

Bohurmir, Another question. Noticed you changed to an Accumulator tank (tank with an air filled bladder inside). Why? Did it increase something? What would be the ideal tank volume and bladder pressure?? Really like your videos, thanks for sharing.

[@BohumirStehlik]

Volume bladder pressure should be little higher than your delivery height pressure. With the ideal tank volume the delivery stream doesn't have any bumps in flow. It is a battery. So too small tank and you will have bumps (or the pump stops to work). Too big tank and it will take years to prime it. With my pump I use 8l bladder tank and it is enough. It also worked with 2l PET. The air slowly escapes from a tank without the bladder so that's why I use bladder tank.

[@charlespalla1978]

Hi, I have been researching different ram pump designs and your waste valve is much better then stock valves. The only question I have is if you tried different size inlet and outlet holes like 1 1/4" or 1 1/2"

Inlet should be the same size as the ram pump. Outlet could be bigger when you have the right weight of the valve.

[@ateamray]

what are the thread sizes of our fittings (metric?). I am in USA and can't seem to find things that match up. Going to build your valve for 1/2 inch ram pump. Should I still use a 2 inch TEE fitting? Or size down to 1 inch TEE fitting? I have 17.6 ft of fall and deliver to 60 ft elevation at a rate of 0.375 gpm (20 ounces in 25 seconds). If I rotate the valve sideway to increase the pressure on swing valve I get 0.409 gpm (20 ounces in 22.9 seconds). Brass swing valve is hissing and leaking. What increase in flow rate could I expect using your valve?

[@BohumirStehlik]

1/2 inch is smaller so you could use 1'' or 1 1/4'' T fitting. This piece needs to be bigger because of the flow between the piston and the wall. The threads are G conical threads.

If we increase the diameter of the manmade valve, can that increase the mass flow rate and higher elevations?

It is all about the intake pipe. If you have big waste valve and narrow intake, the flow rate will actually be the same as the flow rate of the intake. And you will have a problem with too heavy piston.

Mají tam připravené lahve na sešrotování, když je člověk milý, daj mu lahev za kilo. Nebo expanzka z druhé ruky, zbytečné kupovat nové. Řekněme, že se člověk se vším všudy vejde do 1500kč. Ale potom si musí vyrobit ten ventil a všechno spojit dohromady a to stojí čas...

My current drive pipe is a thick pvc 80 feet long, with about 30 to 35 feet vertical height, and my 2 inches swing valve just gave up, after pumping only 90 feet vertical , if i change my waste valve using your design, how high would be my estimated water delivery, ,,,, my water source is a spring with 40 liter per minute volume,,,, hoping for a reply and more power, thanks for the inspiration....

[@BohumirStehlik]

Hello. Wohooo. What a pressure! I mean, 80feets is like 25 meters, and 35 feets of head pressure is 10 meters? Am I right. No doubts that you destroyed the swing check valve. :-) I also think that the swing check valve shut off very fast. The pressure is super high for the valves. It is an overkill. You definitelly need another valve to use the whole potential of the head pressure. But I am worried that the pressure would destroy also my design - the leather would worn out really quickly. How far do you need to pump? With my design I have maximum pumping delivery x15 of the head pressure with 50m intake pipe. Count somewhere around x7 of usable pumping height ratio... Good luck.

[@lukelewallen55]

If I were to make the waste valve size smaller would this mean it would require less water to run it? Also what is minimum liters per minute to run this ram pump?

[@thefiremandave910]

Hiya, it seems the most effective design but how do you attach a pipe to it to take the water where you want it?

[@BohumirStehlik]

Plumber fittings..

why do you mix brass and galvanized components. Could it be all one metal or the other. BTW thank you for response to my question on other video.

Hi sir, Im from the philippines. I have a few question regarding the ram pump, just wondering if its okay to use smaller drive pipe? My pump is 5/4 and currently the only pipe available in my area is 1inch pipe. Thanks. Hope you see. Keep safe and godbless :)

[@BohumirStehlik]

Yes, it should work. Your weight should be just lighter or the distance in the valve smaller. But 1'' for 5/4'' is ok.

[@pingwojak6848]

[@vickrogue]

Does anyone have more information on the leather washers? I have to make a valve for a 3/4 pump and I'm not sure how to make that washer as far as size hole, thickness, etc., where to find them, or if there is any substitute that will work.

[@BohumirStehlik]

I have bought a VERY thick leather and made it myself. Washer should stop the water inside of the 2''=>1'' reduction. The hole in the middle should be only for the screw.

[@javierdelgado5545]

Do you sell and ship the pumps to Puerto Rico? I need one.

[@philipnorman18]

I've built this, Bohumir, put can't get it to work. I made rubber washers for the valve but they are not sealing completely. Is this critical?

[@BohumirStehlik]

Hello. Yes, definitely it is critical that it seals. But also, it could be that you have too little water pressure. Have you used the brass reduction in the valve? They are of a better quality and the surfaces tends to be much smoother.

[@philipnorman18]

@@BohumirStehlik Thanks for the reply. Yes, the seal is probably the problem, I will try something else. I did use brass reductions in the valve.

Good evening , my ram pump which is stream feed uses 2 inches swing valves on rainy days ru s smooth, but this summer the water on my drive pipe is low, can i use a reducer and use a smaller size valve to keep my ram pump running ?

[@BohumirStehlik]

Hello, I think to a certain point you can use a smaller valve. We did it this summer. But not so much smaller because then you would need to change also the drive pipe diameter.

[@nidjikun2654]

What is the size of the delivery valve?

[@BohumirStehlik]

The "T" is 2'' otherwise it is made for 1 1/4'' pump.

[@jesseemugo]

Can I use PPR or PVC fittings as well?

[@andrewcosmatos339]

I'm interested to know why you chose leather for the seal? I assume it's because it would last longer than rubber?

[@BohumirStehlik]

It is much more durable than any rubber. The leather is thick and quite hard.

hello bohumir, whats the size of the second check valve? thanks

[@AdelMalik101]

I am thinking, what if we connect the waste valve to output water flow?! I mean designing the waste valvle in such a way that we can have no wastage and it will go double the flow of water logically.. Back to Fusion and design it.. :)

Not possible, trying to defy gravity and make a perpetuum mobile. :-)

What size drive pipe is this for? 2 inch tee seems big.

[@BohumirStehlik]

Drive pipe is 32mm inner diameter (5/4''). The 2'' is just space. Important is the ending and that's approx 5/4'' (1'' thread)

[@pwrmx24]

@@BohumirStehlik by "ending" do you mean the opening where the water comes out? So your drive pipe is 5/4 then the flow opens up into a 2 inch waste vslve that exhausts out of a 5/4 opening. Is that right? I bought a 1 inch foot valve for my one inch drive pipe ram pump. But where the water comes out of the valve is maybe 1/2 inch. Maybe your design is better because the inlet is bigger than the drive pipe but the outlet is the same size as the drive pipe....5/4 inch.

[@philipnorman18]

I have a 1 1/4" galvanised tee already, so could I base the waste valve around that size or do you say it must be 2"

[@BohumirStehlik]

The 2'' has a meaning. It is easier to attach the construction and the seal to 2'' to 1'' reduction. You need the big size because of the flow.
