Grohe 1/2" Compact Thermostatic Cartridge Assembly — 47439000
The Grohe 47439000 is the authentic, factory-original 1/2" (DN 15) compact thermostatic cartridge assembly engineered for Grohe concealed valves and exposed bar mixer shower systems. Featuring Grohe's renowned TurboStat expansion wax thermo-element, it compensates for incoming water pressure and temperature fluctuations in a fraction of a second to deliver safe, consistent water temperature. If your shower is running constantly lukewarm, alternating between boiling and freezing, suffering from restricted hot flow, or failing to regulate at the 38°C stop, this complete replacement assembly restores complete thermostatic performance.

- Solves Blending Failures: Resolves common issues such as stiff temperature control knobs, lack of hot water, and fluctuating shower temperatures.
- Factory Precision: Genuine Grohe OEM assembly ensures exact seating compression, reliable O-ring seals, and smooth calibration.
Installation Note
Isolate hot and cold water feeds before servicing. Remove the temperature handle and stop ring, then unscrew the cartridge brass body using a 24mm or 34mm socket/box spanner depending on your valve casing. Ensure the valve housing cavity is flushed free of limescale or grit, and lightly coat the replacement O-rings with WRAS-approved silicone grease before seating. Once fitted and water supplies are restored, test and recalibrate the 38°C safety stop position with a digital thermometer. (Note: For reversed supplies with hot on the right, use reversed cartridge 47175000 instead).
