6 Best Aquarium Check Valve of 2024

By John DoeLast update: 2024-07-12

A check valve is a must-have because it contains a gasket or stopper that allows air to flow in one direction (into the tank) and prevents water from flowing in the other direction (out of the tank). It has the function of preventing water from being sucked out of the aquarium if the air pump turns off or stops running during a power outage. Leaking water out of the aviation piping often leads to air pump failure.

Furthermore, it can also be used as a sponge filter, aquarium decorations, brine shrimp hatcheries or carbon dioxide (CO2) spray systems. So how to choose the best aquarium check valve, let's find out more in the review and buying guide.

Here are the best aquarium check valves you can buy in 2024:

              How To Choose The Best Aquarium Check Valve?

              Material, substance

              Most aquarium check valves are plastic and rubber, stainless steel and brass check valves are also available.

              • Metal: Metal check valves are not suitable in saltwater aquariums because they are susceptible to corrosion over time.
              • Kynar: A special Kynar check valve for pumping ozone into the aquarium. Ozone melts other plastics.

              Size

              Check valves need to match the diameter of the air duct. If it is necessary to measure the diameter of the pipe, measure the inner diameter of the pipe. Standard tube is 3/16 inch (5mm).

              How to install a one-way valve in an aquarium?

              First, locate the valve installation as near to the tank rim. Installing the check valve near the pump will allow the water pressure to increase further before it meets the check valve, which can lead to a leak.

              Set up an aquarium air pump (B) and a simple one-way valve (A). The domestic device (C) can be a sponge filter or an air stone.

              After determining the position to install the check valve, use sharp scissors to cut the air duct at that position and then attach each piece of air pipe to each end of the check valve. Furthermore, the valve connection points are slightly tapered at the tip where the spool slides and expands closer to the valve body. This creates a tight seal between the pipe and the connection points. The most common mistake people make is installing the check valve in the wrong direction. Make sure that the arrow on the valve points in the direction of the airflow.

              Test aquarium should be installed:

              • After a hole in the pipe
              • In front of an aviation control valve
              • In front of a gang van
              • After a bleeding valve
              • After or before an aviation connector
              • PSI

              Another important factor to consider is the maximum PSI the valve will face. Brass valves tolerate higher PSI, while plastic is good for low pressure use cases. Setting up a low-pressure valve into a high-pressure situation that can lead to disaster and water damage.

              Temperature

              Be sure to consider the average temperature at which the valve will be installed. Check valves are subjected to extreme hot and cold situations. If you want to use the valve outdoors or on a heating system, know that the valve is equipped for extreme cold and heat above 100 degrees.

              Horizontal and vertical directions installation

              Check valves are installed horizontally or vertically, but not all models are installed in both directions. Double check the drainage setup as well as the valve installation before ordering.

Depending on how the drain is set up in your home, it may be necessary to reposition the sump pump or use couplings.
