How To Install Shown in Images.

Non Return Valves allow your pump to charge the system up to your pumps rated pressure once an outlet tap/shower is closed. After age/scale build up they no longer seal and allow back flow which makes the pump turn on and off when no outlet is open. This is why a quality non return valve is needed and has to seal 100%.
