ADA - Check Valve - Non-return valve - For the supply of CO² and air to the aquarium tank

Using advice :

Connect the pressure resistant tube to the inlet side of the check valve. The internal valve of the check valve may not function properly with the use of silicone tubing, as gas escapes from inside the tubing and causes a reduction in pressure.

Install the check valve where it withstands high water pressure. If there is high pressure on the flow side of the check valve, the check valve may not operate properly. Do not install the check valve at an extremely low location in the tank.

The check valve is a consumable product that should be regularly inspected and replaced. If the valve is damaged, the cO² can leak. If the valve does not work properly for a long time, water can reach the valve or the C0² regulator. It is necessary to periodically check the performance of the control valve.
