+1 ... can you believe it?

 

I don't have check valves though, because honestly, I was in too much oblivion to know about them. I use a big enough container for fuge so that I have a 20g back-siphon space. I have tried little holes drilled in pipes - they don't help much if at all, and still have to be checked a lot to make sure they aren't clogged.

My sump raises a quarter of an inch when the water shuts off and most of that is the drain plumbing and overflow emptying. I have one return half out of the water. No valves, no floods.

I am using the flapper style. I will try greasing is. Thanks

Wait, wait, wait. The flap is leaking? If yes, don't put silicone grease on the flap. Throw out the check valve and buy a new one.

There's nothing wrong with using silicone grease on rubber parts. The flapper tends to get caked with calcium scale and then needs to be cleaned and re-lubed in order to work properly. No need to buy a new one- just do some simple maintenance and you'll be fine. These type of check valves will last until the rubber cracks.

Tony- those are non serviceable check valves that are glue in only.
