overflow build

[tank a holic]

I'm making a diy pvc overflow and I can't find an air check valve. Anyone know where i can find them?
Lowes don't have any

You can get air check valves at any of the big pet stores or online where aquarium products are sold. Let us know how it turns out. I built one once and tested it out...it worked fine but decided to drill the tank instead...more reliable IMO.

Walmart has air line check valves.

Basically any fish store has them

If I may ask why do you need them?
Overflows work fine with none installed for me anyway.
but that's just me

Just the one's I've seen have em... guess I'm just following suit. But I finally found one so I'll stick it on

If it's to maintain siphon I suggest you not use one. It will only fail.
I run a line from the top of the hob part to a powerhead to suck out the air bubles and prevent siphon break.

good idea... I'll drill the hole and put in the valve, then get a PH and hose to replace it
