Grohe Aquadimmer Diverter & Flow Valve — 49084000
The Grohe 49084000 is an authentic, factory-original Aquadimmer flow control and diverter valve assembly designed for modern Grohe exposed thermostatic bath and shower mixers. Positioned on the water volume handle side, the Aquadimmer is a dual-function mechanism that regulates water on/off volume and seamlessly switches the water flow between two outlets (such as between the bath spout and hand shower, or overhead shower and handset). If your shower is dripping from the outlet when switched off, passing water to both outlets at the same time, or stiff to rotate, replacing this internal valve restores full control.

Installation Note
Always isolate incoming hot and cold supplies before dismantling the mixer. Remove the flow/diverter control handle, trim cap, and stop ring to access the valve body. Unscrew the retaining headwork using the correct sized spanner/socket. Clean any limescale build-up inside the brass chamber, lightly coat the replacement O-rings with WRAS-approved silicone grease, and align the locating lugs into the valve housing before tightening. Do not overtighten during installation.
