Summary
GROHE 47477000 Non-Return Valve for Thermostatic Mixer Valves
GROHE 47477000 is a non-return valve used inside selected GROHE thermostatic mixer shower and bath/shower valve assemblies. It allows water to pass in the intended direction while helping to prevent reverse flow through the mixer, supporting correct hydraulic operation of the valve.
The valve is an internal service component rather than an external control. Older GROHE service documentation may identify the same part using the shortened reference 47 477.

Before You Order
Confirm the valve model and existing part reference before ordering. Do not select this non-return valve from the 31.8mm fitting thread diameter or 25mm plastic NRV diameter alone, because these measurements do not establish fitment.
