Grohe 47117000 Cartridge (Without Plastic Spline Adapter) - GR-47117000

Summary

GROHE 47117000 Ergomix Basin Mixer Ceramic Flow Cartridge Without Plastic Spline Adapter

The GROHE 47117000 is a ceramic flow-control headpart for the Grohtherm Ergomix thermostatic basin mixers listed below. It is supplied without the plastic spline adapter, so the condition and availability of the existing adapter must be checked before ordering.

This cartridge operates the basin mixer's water-flow control, opening and closing the water supply through the spout. It is separate from the thermostatic cartridge that regulates the mixed-water temperature, and should not be confused with that component when diagnosing a fault.

Fault Symptoms and Ordering Checks

Persistent dripping from the basin spout when the flow-control lever is fully closed can indicate a worn or damaged ceramic headpart. Inspect the headpart and its sealing O-ring when investigating a shut-off problem. A damaged or missing plastic spline adapter requires separate attention, as that component is not included with this cartridge.

Match the exact mixer model and existing headpart before ordering. The nominal size alone does not establish fitment. Temperature instability should be investigated separately, as the flow headpart does not perform the thermostatic mixing function.

Fitting Notes

Isolate both the hot and cold water supplies before dismantling the mixer. Remove the lever and associated operating components to access the headpart. Follow the mixer-specific spindle and stop-ring alignment instructions during reassembly, inspect the seals, and check for leaks and correct shut-off after restoring the supplies.
