Check Valve for Flex Tubing

[freepizza80]

Hello All. Does anyone know where I can get a check valve for my FLEX TUBING return? I have 3/4 inch flex tubing going from the aquarium to the sump. Trying to install a check valve but can't seem to figure out how it would work with flex tubing.

maybe you can put clamps? Also check valves you have to clean them all the time. I just had a siphon break at the input side which prevent excess water going to the sump.

If you must, barbed fittings in and out of the check valve with hose clamps.

But as said, in general check valves are bad mojo, best to be avoided.
