Grohe 47751000 Adapter for Aquadimmer 12433000 Cartridges

SUMMARY

GROHE 47751000 Waterway Adapter for 12433000 Aquadimmer Bath and Shower Cartridges

The GROHE 47751000 is an internal waterway adapter for the 12433000 Aquadimmer cartridge in selected thermostatic bath/shower mixers and shower systems. It sits inside the mixer body, behind the Aquadimmer, and is supplied as a separate component from the flow and diverter cartridge.

The adapter forms part of the flow-control waterway, with four external O-rings sealing it within the valve housing. The Aquadimmer cartridge controls water flow and outlet selection; the 47751000 adapter is not a thermostatic cartridge and does not regulate the mixed-water temperature.

Before Ordering

Check the exact mixer or shower-system code, its production version and the existing internal assembly. The presence of a 12433000 Aquadimmer cartridge alone does not establish that your mixer uses this adapter. Compare the old component and the model-specific parts diagram before ordering.

The legacy model references above identify the original mixer versions, not every later product carrying the same range name. For 27932000, match the July 2017 parts arrangement rather than assuming that an earlier version uses the same adapter.

Fault Checking

- - Symptom: water continues dripping from the shower head or bath spout when the flow control is fully turned off

- - Likely cause: a fault in the flow-control assembly, which may involve the Aquadimmer cartridge, its seal, or a damaged adapter and its O-rings

- - Solution: inspect the cartridge, adapter and sealing surfaces, then replace the component responsible for the fault; replacing the adapter alone will not repair a worn Aquadimmer cartridge

Fitting Notes

Isolate both hot and cold water supplies before dismantling the mixer. Follow the service instructions for the exact model, inspect and clean the accessible components, and refit the adapter in the correct orientation without damaging its seals or the valve housing. Use the lubricant specified for the installation. The thermostatic cartridge is a separate assembly; its retaining-ring tool should not be treated as an adapter extraction tool.
