Check Valves

Recommended Posts

I'd like to put a check valve in my return line from my sump to prevent a syphon if my pump shuts down. All of the check valves I've found have metal springs in them, and I really don't want to use them. Any suggestions? Thanks in advance.

no solution as far as the valve goes but to prevent siphon you can drill a small hole in the return line, right above the waterline. As soon as the pump turns off that hole will pull in water and break the siphon, this is what i have done on mine

I might try that. Thanks :)

Check valves are not a good idea in a return line. If your sump requires it then you either need to get a bigger sump or make sure the outlet from your return line is very near the surface of the tank, or a siphon break as Jordan recommends.

I drilled a small hole in the plumbing just above the high water line in the tank, and it worked great :) Thanks for the help Jordan.
