Check Valve

  • Sale
  • Regular price $ 1.99


We use these check valves to keep water from siphoning out of the tank when the power is out. We also use these check valves on our co2 systems. They are made with a rubber flapper instead of a spring like some of the cheaper ones. With co2 they do break down over time we find we get 3-5 years of use out of one.

Check valve

Looks well made. Will need to see how it holds up. My old ones from a different vendor clogged up over time with use as my tanks are located outside in a fairly open terrace area so dust tends to make it's way into my air pumps.

Buy them

Although this is an inexpensive product, it seems to be effective and well made. I have been using these for a couple months now and have determined that I can trust them. I have tested them by attempting to get back-flow. I have tried to induce a siphon similar to what would happen with a pump failure and found no leaks. With pressure far beyond normal siphon pressure they hold tight. Also important, they do not induce abnormal pressure in the forward direction. I trust these valves.
