  Best check valve

  Posted by Kevin Castlan on 6th Mar 2025

  Simple and works, feels very heavy duty not sure why it’s so heavy. One thing I like is it’s easy to clean vs my old Atomic valve which felt impossible to clean. This one you just soak in vinegar and blast air through it.

  Easy to install. Has an arrow to show flow direction, so easy to orient.

  There is nothing special or nothing wrong about this product. It is just a reliable check valve that do the job. Quality looks good.

  Super Check Valve

  This works really good. I had trouble under standing which way to attach them - the larger side gets attached to the line going to CO2 diffuser. A arrow or something may be nice. Also push the CO2 tube well into this check valve for it to work properly.

  Check Valve

  The check Valve has given out in less than 2 months. Water is reaching my regulator, but since the bubble counter itself has a check Valve I am safe for now. Not worth it for 20$.

  Heavy duty valve.

  Very nice and extremely heavy duty. This guy is literally heavy, and GLA tubing is perfect fit. Super happy with this one.

  This is my new favorite check valve for my reactor. Its stainless steel and the seals always working.

  Excellent product

  For those who are wondering, the LARGE METAL END points towards the DIFFUSER. With that being said, within 5 minutes of messaging customer service, they sent a response to answer my question. Product is heavy and well built compared to other (even other brand name) check valves. 5 star.

  Last check valve you will ever need.

  Posted by Joshua Sterling on 12th Feb 2022

  Check valves have always been a pain in the ass for me until this one arrived. Its heavy, and it feels substantial and everyday its always working. Instead of me freaking because water had passed the check valve. Not with this bad boy, I just ordered 3 more just because.
