The check valve on my HVAC condensate pump stopped working. This caused the pump to loss efficiency and run more often. I purchased these so water would stop flowing back into the condensate pump. I tried both valves, facing correct direction, and neither of them worked. The water still flows back into the pump. I'm going to try another brand.

Bought these to allow excess crank pressure out of my crank case while also keeping any vacuum for necessary operation. So far I’ve only started the bike and let it run but have not gone for a ride, but it seems to be working as intended.

Check out my picture. The hours is 3/8" ID (see labelling on hoes). Compare to labelling of the package these came in and the one connected to the hoes. 🤨

Intended to use this to prevent siphoning, but the valve won't open with the small water column behind it. Might be good for usage with pumps, but not for what I needed it to do.

I’m running 30HG through these and they have held up nicely.

These units worked well to stop backflow and siphoning in my RV water system. I would recommend these if you have water pump cycling due to air loss or pressure loss.

Item was properly sized for a 3/8 inch hose. On the downside, it requires quite a lot of pressure to open the one way valve. On the plus side, there is virtually NO back flow after pump shuts off. Definitely, not for use in any situation that requires a gravity fed flow.

Worked perfectly for my purpose. Only problem is that it's not marked which direction it should flow and a check valve only works one way. I just blew through each opening to figure out which direction would prevent air from going through before installing it.
