Check valve with ball question

5 years ago

My sewage pump is broke, luckily the switch broke in the on position and no the off, so the pump is continuously running atm (yes I opened it up and made sure nothing is stuck on the float). I found a check valve ball valve combo. It's silenced by a spring loaded flapper. My 2 inch pvc pipe goes pretty much straight up to the ceiling of my basement from the sewage ejector pump, but this check and ball valve combo says to only install the valve in the horizontal position, not vertical. Will this cause major problems if I install the check and ball value combo? I'm guessing solids could come back down and block the flap of the check valve, but that could happen with any check valve

Your asking if you should install the check valve in disagreement with the manufacturer's instructions. What do you want us to say, "sure, no problem, those guys don't know what they're talking about"? Come on, be real. Unless you can understand the valve mechanism and the forces that make it work properly or improperly, you shouldn't be installing it contrary to the vendor's instructions.

Why does it have to be a check/ball combo? Why not bite the bullet and install a separate ball valve and check valve. I use the check valve below and they are indeed quiet.

The previous install had a check valve no ball valve. I got mixed information whether a sewage ejector should have a check valve facing vertically or not, but almost all of them agreed there should be a ball valve to stop junk from falling down if the pump needs to be looked at. To save time and have less areas for leaks, I went with a dual system.

These are my setups:

Sump pump-

Sewage pump-

The check valve also provides the union connection to be able to separate the pump from the house piping for service.

The picture below was my old set up. My check+ ball valve combo is plastic pvc similar to your check valve HU, but when it ran it sprayed from the bottom union where the pvc coming from the ejector met the bottom of the valve against. It spray all against the wall you see in the picture. Yes, I had the check valve on properly and have a hole drilled in the bottom of the pvc coming from the ejector.

I was thinking I would cut a small piece of pvc for the top and bottom of the new check+ball valve, jam the pvc in the holes very well, twist connectors on the check+ball valve to seal well, then use those black connectors in the picture below (new ones) to connect the pvc coming from ejector to the bottom of check+ball valve and the top to the rest of my piping. Will this create more problems or is this a good idea?

Update: i switched to an independent check valve and independent ball valve. The spring loaded check+ball valve combo seemed to go against allowing the water to be ejected freely through the pipes.

I put everything together with the check valve below the ball valve. The check valve and ball valve are glued together by a very shirt piece of pvc. I have a rubber pvc coupler on the top of the ball valve and rubber coupler below the check valve. I did this because my previous install had this set up and saved leak free. For some reason the top coupler leaks when the ejector goes off. Any recommendations? Should I just glue everything together at the top to make a better seal?
