Check Valves

Protect your aquarium pump from potential back filling or flooding by installing aquarium check valves from Finest Filters. Discreet and cost effective, check valves prevent water from returning to the air pump by making sure water can flow freely in one direction but not the other.

Aquarium air pumps keep oxygen flowing safely through your fish tank. However, there are occasions when a pump can stop working as it should, which is where your check valves come in. If there is a loss of power causing your air pump to stop working, or if the air pump tube comes away from the pump, then the pump will begin to suck water back inside it. Check valves stop this from happening and return any water back in the right direction.

At Finest Filters, we sell high quality air pump check valves in packs of 5 or 10 that can be easily installed and require little to no maintenance. Check valves can also be used in CO2 systems, such as the Ista Spring Check Valve, which can be used for both aquariums and CO2 systems. We also supply air pump accessory kits that have everything you need to set up your aquarium air pump, including our standard air pump check valves. 

Check valves are a low cost and effective way to ensure that the water in your tank will not be drained out should anything go wrong with your air pump - they’re a simple measure that could save a lot of time and expense.
