Hansgrohe 95033000 16mm Non Return Valve

Summary

Hansgrohe 95033000 16mm Non Return Valve

Hansgrohe 95033000 is a 16mm DW 16 non-return valve for selected Hansgrohe shower valve and thermostatic mixer assemblies. This check valve sits in the waterway to help prevent reverse flow between supplies and is used where the valve parts diagram specifies Hansgrohe 95033000.

The non-return valve helps protect the mixer from hot and cold crossflow. Common signs that the valve or surrounding inlet components may need checking include unwanted transfer between hot and cold pipework, unstable shower temperature, reduced flow, or a thermostatic mixer that does not respond correctly even when the cartridge is serviceable.

Technical Details

Before You Order

Check the exploded spare parts diagram for the shower valve before ordering and confirm that the required non-return valve is listed as 95033000 / DW 16. Do not order solely from the 16mm size, as other Hansgrohe non-return valves such as DW 15 / DN10 94074000 are different parts.
