LF 3/4 pvc check value

[abcha0s]

I would avoid check valves. They seem like a good idea but really aren't. You should design to accommodate the back siphon if the pump loses power.

I used check valves on my return lines. When I lose power, they just bounce. One day I will probably get motivated and take them out.

You can purchase these and many other hard to find plumbing supplies at Western Pump in the SE.

For an alternate opinion, I've been using the same check valve for 6 years, no issues with it at all

It's got a little flapper thingy in it. I guess swing? It's a 1" valve I picked up years ago, I think maybe at J&L. Not sure they carry them anymore.
