One way valve for fish and aquatic animals

I use these valves to ensure the pressure goes one way to the pressure cup. Works great and much cheaper than the ones recommended by Fuji Spray.-F

Pros
  • Satisfied so far
Cons
  • No automatic

Poor quality best at Fish & Aquatic Pets

Very cheap 2 component strings, some of them don't hold together straight out of the box, the few that worked I don't expect long.

Pros
  • 1 year trial
Cons
  • Ugly packaging

Too much back pressure

These check valves create so much back pressure my compressors can barely pump air through them. I've never experienced that with any other check valve.

Pros
  • Sturdy construction
Cons
  • Useless features

Great valves - fish and aquatic animals

I use them in my cpap So Clean system. I put them on the hose between the water tank and the So Clean machine to keep water from getting back into the So Clean machine during the cleaning process.

Pros
  • Best
Cons
  • Almost everything is fine

Looks better than the ugly reds

Glad to see them in black instead of the usual red. I've only used one so far with no problems. Just make sure you blow in to test it and point it in the right direction. I didn't actually need 20 of these so I probably have a 5 year supply now. I hope my fish live that long!

Pros
  • Price
Cons
  • Little things
