Some work, some don't, some whistle VERY loud!

It's a bit crap but be sure to test before installing. Some didn't work and many whistled. Out of a pack of 10 I only found 3 that were acceptable.

Pros
  • Overall Length: 51mm Color: Black
Cons
  • Expensive

High failure rate of aquarium pumps and filters

1 out of 4 check valves actually worked. As only 1 was needed it does the job but it was very frustrating to get through the first 3 as they were forcing water back through the CO2 line. I use this for CO2 in an aquarium at around 35psi and 1bps.

Pros
  • Includes: 10 pieces of air pump check valves, necessary parts for an oxygen supply system for an aquarium with air pumps.
Cons
  • Safety

2 of them arrived broken in the package!

These work fine but 2 of them were broken in the packaging. One doesn't appear to be broken, but no air is leaking. Otherwise I'm satisfied. I bought more than I need just in case. I would recommend doing the same.

Pros
  • Application: Compatible with commercially available aquarium air tubes with an inner diameter of 4 mm. Ideal for aquarium, fish tank, tackle shop etc.
Cons
  • Fits

Yes, he whistles, but you can fix it with your own hands.

So, after some trial and error, I found that the whistling is due to the check valve vibrating too much. That would have been fine at lower settings on my air pump, but as I increased the power the whistling was non-stop. All my tanks are in my room so that's not an option. They are all powered by air pumps and through trial and error I figured out how to make everything almost silent. For this check valve, the solution was as simple as placing the air pump on a small towel and placing a rock…

Pros
  • Function: Sealed one-way check safety valve greatly protects the air pump by preventing water from flowing back into the aquarium in the event of a power failure.
Cons
  • Empty
