Rainbow 1.5″ Or 2″ Non Return Valve – (2 Lb Spring)

Rainbow Non-Return Valve

Prevents back flow of water in pipelines.

Can be installed using 1.5″ pipe or 2″ socket.

Best to install with a socket union either side, so you can clean and maintain.

Advised to install alongside any chemical dosing equipment to avoid chemical back flow into delicate elements such as heaters.

If using with salt water then we recommend flushing with fresh water every 6 months.

Installing a chemical feeder is the best way to use chlorine tablets to sanitise your pool. A non return valve is a necessity to have with it. Installed before the feeder it prevents back flow of high concentration sanitised water from damaging delicate pool equipment such as heaters.
