Great Addition to any Aquarium Setup

According to my experience this non-return fitting is a great addition to any aquarium setup. The transparent plastic design allows for easy monitoring of water flow, while preventing water from flowing back into the pump .The only drawback is that it MAY require some extra effort to install properly. Overall, I highly recommend this product for anyone looking to improve their aquarium filtration system..

Pros
  • Prevents water from flowing backwards, keeping the aquarium and filtration system safe.
Cons
  • Fragile and prone to cracking if mishandled or exposed to extreme temperatures.

Does not stop airflow

I bought these to provide unidirectional airflow and pressure holding capacity. The air usually flowed in one direction, but it was not possible to maintain this air pressure. Each of them releases air, albeit slowly, but not well enough for my application. Thought this fact would be useful to know. BTW I tried all 10 and they worked the same way.

Pros
  • DO NOT use with CO2 system. Check valves are designed for common aquarium air pumps.
Cons
  • No power
