Grohe 47923000 Flow Control Handle

Summary

GROHE 47923000 Grohtherm 2000 Bath Shower Mixer Flow Control Handle Chrome

The GROHE 47923000 is a chrome shut-off and flow-control handle for selected Grohtherm 2000 thermostatic bath/shower mixers. It is the external operating control for the Aquadimmer mechanism, not the temperature-control handle or an internal cartridge.

The paddle-shaped handle operates water shut-off, flow adjustment and selection between the bath and shower outlets. When correctly fitted, the central position is off, turning anti-clockwise opens the bath spout, and turning clockwise opens the shower outlet.

Before You Order

Check the exact mixer model code, existing handle and fixing arrangement before ordering. Grohtherm 2000 includes different control designs, so the range name or appearance alone does not confirm the correct part. Check whether you need the external handle, its cover cap or an internal flow-control component.

The following are separate mixer components and servicing items, not the contents of the handle. Select them according to the mixer model and the fault being repaired; the thermostatic cartridges and temperature handles are model-specific.

• GROHE 47751000 Aquadimmer Waterway Adapter - separate component fitted behind the Aquadimmer
• GROHE 47917000 Temperature-Control Handle - opposite control for 34174001 and 34464001, not the flow-control handle

• GROHE 0305600M Aquadimmer O-Ring - seal associated with the 12433000 cartridge
• TACSIL TAC86 3g Cartridge Silicone Grease - for lubricating cartridge seals during internal mixer servicing

Checking a Flow-Control Fault

• Symptom: Water continues to drip from the bath spout or shower head after the flow control has been turned off
• Likely cause: Wear or damage to the internal Aquadimmer, its O-ring or the associated adapter and seals
• Solution: Check the internal flow-control components before choosing repair parts; changing the external handle alone will not correct an internal sealing fault

Installation Note

Isolate both hot and cold water supplies before dismantling the mixer, and follow the instructions for the exact model. Keep the handle and Aquadimmer components correctly aligned when refitting, then check the central shut-off position and operation of both outlets.

For help identifying the correct control, send photographs of the mixer and removed handle, together with the mixer model code, to our part identification service.
