Where to buy check valves

[D3DPrintedThingz]

Hello - I am looking to purchase a check valve for my return line. Most of what I am finding has a metal spring that activates the check valve. I obviously cant use these types.

Where do you find check valves for aquarium use?

Bulk Reef Supply has swing check valves (no metal I believe), but most people would tell you to design your system without check valves period.

If you drill a hole in the top of your return loc line and keep it bent out of the water, your backflow will be minimal.

Don't know what size you need but these work good. They have different sizes.

Look for a Wye Check valve if you think you need one.
