Protect your pumps and other aquatic equipment from a counter-flow of water in the system by just installing the Azoo Plastic Check Valve from Pet Store. This check valve is a device used to prevent water from back-flowing to the carbon dioxide (CO2) regulator of your equipment.

The check valve is often used in pumps installed under the tank so that the pump does not siphon water in itself when a power outage occurs. The sudden backflow can cause damage to your pump, as well as to your aquarium. It is, therefore, important to set this up in such a way that it is secured and in place at all times.

The Azoo Plastic Check Valve is positioned in between the CO2 regulator and the bubble. The device automatically stops the flow of water when power is out. This valve is made of premium quality plastic that is strong to withstand water and air pressures. It is long-lasting, and it can outlive other types of check valves. It does not easily crack or leak.

Unlike other check valves, this plastic valve is free from rust and corrosion and is safe to use. It is also easy to install. This check valve ensures you that the water is always flowing in the right direction, assuring you your regulator can perform its job efficiently and effectively, and that it can live longer.
