How To Make a One-Way Check Valve - For Cheap!!

The most expensive parts of a water pump, or DIY Super Soaker, are usually the check valves. In this project, we're making some from scratch, for as little as $0.35 each.

WARNING:
The pressure tests and claims made on these check-valves is based solely on my personal experiences with the ones demonstrated in the video. Individual results may vary, and caution and care should be taken when loading the valves with high pressure. The risk of higher pressures is that the balls may be forced from the adaptor, shooting out like projectiles. High pressures may also cause the ball to lock up, preventing normal operation of the valve, or possibly even structural failure of the valve altogether. These valves are not made, or claimed, to be used in any heavy duty operations. Use of this content is at your own risk.

Project History & More Info:
I wanted to build a PVC water pump, but the check valves were around $10.00 each. That seemed a little steep for a PVC build, so while looking for alternative options, I settled on this design, which is about the cheapest, while still being practical and useful, that I could imagine.
In my testing, the valves work great with air and water. Air pressures up to 60PSI seemed to be fine for normal operation, while pressures above 60PSI occasionally caused the ball to lock into the O-Ring, and required substantial "back-pressure" to unlock it.
If you try using rubber bouncy balls as the valve mechanism, only use them in very low pressure applications like blowing up balloons, and possibly for improvised water guns. Relatively high pressures used with these balls seems to eventually force them out of the adaptor, and can shoot them out at surprising velocities.
Overall, I'm really happy with the valves because they can be fit into any part of a PVC system, and can be duplicated quickly, easily, and for very very low cost.

    Thanks Dan. Around 60PSI the ball had a tendency to lock up in the O-ring. This could probably be remedied by using a thicker O-ring. I took it all the way up to 135 PSI, but the ball gets difficult to release. 50-60PSI should be way more than enough for any application involving PVC parts.

    I found some rubber balls, but they were pretty large. 25mm leaving very little room in the fitting, and no room for the pipe. I cut the ball in half and cut some notches in the end of the pipe. Then I glued the pipe in making sure not to push it in so far as to press the half ball. I left about 1/4 inch of room for it to move. Works great.

Now what I would like to see is how to make a cheap and simple swing check valve (where the 'valve' moves up out of the way of the flow) for use in applications where there is say sand or small gravel in the water that you are moving with your hand pump.

    If you are unable to access electricity (typical scenario in any 'apocolypse') or non-homemade versions these valves, a pump made using these to fill a large reservoir with water would be much more efficient than say, using a pail or bucket to fill one with water. It also allows you to set-up an accessible pump to water source without having to actually go to said water source (which may endanger you if it not in a safe area).

    You could probably glue the O-Rings into place using Automotive Weatherstripping Adhesive (available from most auto parts stores), just be careful not to get any on the side the acrylic ball contacts because it may result in an uneven surface which may not seal as well then. Allow the adhesive to dry fully before adding the ball and gluing everything else together though (in case you maybe have a little too much of it and it drips back into the main chamber of the check valve).

    Look in the description, it says up to 60psi works but anything over occasionally caused the ball to lock into the O-ring. This could be fixed by using a thicker, same o.d. but smaller i.d., O-ring as tolerances would be tighter and therefore more pressure can be applied. As for the Rubber ball, it says it can be used in low pressure, but it could probably be used for high pressure also. Basically any pressure up to the ball wearing down enough to slip into the pipe, could be tested on a non-cemented version so it can easily be taken apart and inspected for wearing of the ball.

    Great vid, I build aquaponics systems and I hate having metal one way valves. Was the brad you used stainless steel? I may replace with a plastic rod of larger diameter. keep on doing what you do best. Its much appreciated.

    Logic Bob Nothing from what I can tell. The check valve seems to be the weak part of this pump, especially since he doesn't give us a size for either the ball or o-ring. Annoying frustrating project, wish I checked more into it before plunking all this money down. Probably will just end up buying check valves since these acrylic balls are expensive, and this is costing waaaay more than $0.35 each to build. More like $15/ea.

    +pk1225 I believe the ball is 3/4.. O-ring is hard to find. Has to be a thick one. I have everything built except for the o ring. None in my assortment seem to fit and be thick enough.

    +ABikerLife Thanks for the reply. I couldn't see any way of making this work as shown and still have decent flow. If you use PVC with an I.D. of 3/4", the 3/4" ball would cut off all the flow regardless of whether it's seated or not. So it needs to be smaller. And it seemed like the o-ring would have to be unusually thick, which would cut flow down too. I think the PVC pump is brilliant but these homemade check valves leave a lot to be desired... but the Home Depot ones flow great, and only cost $3.50 each.

    Yeah, I'm in the same boat pk1225​. I've been having a helluva time getting this to work. I wanted more flow, so I was trying to use a 1" rubber ball and larger, 1.5" fittings. I had a great, compact solution with great flow, BUT the small seam on my rubber balls prevented it from sealing. I'm determined to make the check valve myself and I tried to think of some other designs but I was having the same problem you describe. I ended up ordering five 1" acrylic balls from eBay for about $15. I found my local OSH/Orchard had a great assortment of o rings, but like you both mentioned, it has to be really thick or it will have to be glued in place. I'll try to update this thread when I get the acrylic balls.

    Do you know if this constricts the maximum volume of flow through the pipe? Also, you mention some tested air pressure ratings? Did you ever find the pressure at which it fails? Great stuff...

    +BrokenRRT that makes no sense. Since it can turn freely when unlocked, there is no way to be sure it blocks when needed. I don't think it will close every time..

    The flat part matches up with the end of the tube you inserted so the ball doesn't roll around or get stuck into the tube, the round part is only on one side so that's the side that seals.
