To prevent a backflow of water to the pump, this Salamander Non-Return Valve can be fitted between the pump and anti-vibration coupler. This valve also prevents any water from lying in the pump when not in use, which could lead to congestion.
It's important to note that the Non-Return Valve is to be installed on the Hot Outlet, between the pump and flexi hose.
