Great product in air pump accessories

Bought because cheap plastic parts kept falling on my CO2 system. You didn't miss a drop of water. Check valve that works! Good product!

Pros
  • Best in niche
Cons
  • Almost everything is there

Confidence in quality

quality that does not need to be replaced like plastic versions. It's good to have two - one for each supply line. The light weight of the metal also meant that they did a good job of loading the houses outside the tank.

Pros
  • great product
Cons
  • ---

Works as expected - Aquarium Pumps and Filters

Simplicity and functionality, nice little arrow showing flow direction. I paired it with a built in CO2 diffuser in my planted tank and it wouldn't let water flow back into the pipe when the CO2 timer was off. In order for air to flow through, there must be pressure.

Pros
  • Absolutely Amazing!
Cons
  • Reliability

They still work!: Aquarium pumps and filters

Switched to these from Fluval plastic check valves and still no problems. My plastic checks are starting to leak over time. There are no leaks with them, checked with soap bubbles. The same Chinese check valves that other companies sell here. Unless you get 2 for almost the same price πŸ‘πŸ‘

Pros
  • New to my collection
Cons
  • So far so good

This product just doesn't work.

This product is the deepest thing I've ever bought. Definitely do not buy this check valve. I mean really how to screw up the check valve?!?! I wanted to put zero stars but the system didn't allow it. Revain, seriously consider removing this item from the shelves.

Pros
  • practical item
Cons
  • makes me nervous

They are specifically designed for CO2, not air

If you try to use them with an air pump you're going to have a bad time. CO2 operates at a much higher pressure but less volume when your air pumps are trying to push a larger volume of air to low pressure elements like foam filters and airstones. Also, I thought at first they might be defective and not leaking as I couldn't force air through them by hand or with a pump, but decided to hook them up to my CO2 systems to make sure I knew how much pressure was required. to overcome the diffusers…

Pros
  • Rugged construction
Cons
  • Non-automatic
