Review on AQUATEK Premium Brass Check Aquariums by Jasmine Leon
Works at pressures of 20psi and above.
I just installed this check valve in my aquarium's CO2 system after my previous check valve failed (in the Red Sea 13 years ago). This check valve would not allow gas to flow below 20psi even after waiting for the line to be pressurized. If you're happy with 20psi, then looks like a good check valve (I've had it up and running for about noon now, so no guarantee of durability yet). I definitely like the brass construction and secure hardware. Let's hope this lasts.
- Permanent test results
- Slightly dented
