Hansgrohe 96737000 Non-Return Valve Backflow Preventer Cartridge
The Hansgrohe 96737000 is an internal non-return valve and backflow-preventer cartridge used in selected Hansgrohe thermostatic mixers, showerpipes, bath mixers and kitchen mixers. It is also described in Hansgrohe technical information as a check valve with the designation NV15 / DN15.
The valve allows water to pass in the intended direction while helping to prevent reverse flow and crossflow between the hot and cold supplies. A worn, contaminated or obstructed valve can contribute to hot and cold water crossing between supplies or reduced water flow through the fitting.

Check the full Hansgrohe article number and the construction period of the mixer or shower system before ordering. The same product family can contain different internal parts across production revisions. Do not select this valve from appearance or the NV15 / DN15 designation alone.
Isolate the water supplies before dismantling the fitting. Note the fitted direction of the existing non-return valve and follow the model-specific Hansgrohe servicing instructions. Some assemblies use more than one valve, so check the relevant spare-parts diagram before deciding the required quantity.
Fitment is confirmed by exact article number. Construction periods and finish variants differ, so the complete code and production date must be checked.
The 95843000 handle fixing set is relevant only to the selected Ecostat Comfort controls in which it is specified. It is not required for every Hansgrohe product using the 96737000 non-return valve.
