Non-Return valves for swimming pool pump and filtration systems allow water and debris to enter your pool or pool pump filtration (dependent upon where the valve has been fitted) but not go back out. This will allow pool water to be filtered and then returned to the swimming pool without issue. These non-return valves are easy to install to any existing pipework.

Non-return valves or check valves can also be used with salt systems. It is important that salt treated swimming pool water does not return to your swimming pool heating system as it causes corrosion.
