Rated 1 out of 5 by Hari Waste of money
This is one piece of equipment that I bought which is a complete waste of money. Firstly, you assume everything works until a scenario where it is tested. I have it inline with my air-tubing that supplies CO2 from a DIY setup instead of air from a pump and whenever the CO2 is turned off, after a few minutes, the water comes down not only until the check valve but through and past it. This is the very purpose of having a check valve and this one does not serve the purpose at all. The finish looked nice and thats the reason I bought it but I now know that its a piece of junk that I wasted my money on. I should have gotten a higher quality check valve.

This is very important to have in case your air pump ever turns off and the water back siphons. It does its job and stops the water. Only concern is that it weakens the airflow slightly and is overpriced for what it is.
