Grohe Avensys Control Unit Assembly — 47598000
The Grohe 47598000 is the authentic factory-original control unit assembly designed specifically for the Grohe Avensys dual-control mixer shower range. This core mechanical assembly houses both the flow regulation headwork and the thermostatic temperature blending mechanism. If your Avensys shower valve is constantly dripping from the shower head, failing to regulate water temperature, stiff or seized when turning the dials, or leaking from behind the front control plate, replacing the complete control unit restores full original factory operation without having to replace the entire valve body.

Installation Note
Always isolate hot and cold water supplies before starting work. Remove the control knobs and faceplate to access the brass valve body. Unscrew the securing screws to withdraw the old unit. Clean any limescale or debris from inside the valve chamber and lightly lubricate the replacement rubber O-rings with WRAS-approved silicone grease before sliding the new unit into place. Do not use petroleum-based lubricants (such as Vaseline), as they degrade rubber seals.
