Grohe SmartControl Flow Control Cartridge — 48359000
The Grohe 48359000 is an authentic, original-equipment flow control cartridge assembly engineered specifically for Grohe SmartControl and Grohtherm SmartControl concealed shower and bath mixer valves installed with the Grohe Rapido SmartBox (35600000 / 35604000). This precision mechanism powers the signature SmartControl push-and-turn action: pushing the button starts or stops water flow to the chosen shower outlet, while rotating the outer dial adjusts volume from a gentle spray to full flow. If an outlet continues to drip when turned off, fails to latch/click on and off, or will not adjust water volume smoothly, installing this replacement cartridge restores original factory operation.

Key Features
- Dual Push-Turn Function: Restores crisp mechanical push-button on/off flow actuation alongside accurate rotary volume throttling.
- Cures Dripping Outlets: Replaces worn internal shut-off seals to eliminate persistent dripping from overhead shower heads, handsets, or bath spouts when clicked off.
- Fixes Sticking Push Buttons: Resolves common issues where the button fails to latch in, stays depressed, or becomes stiff to rotate due to limescale buildup.
- 100% Genuine Grohe OEM: Direct factory replacement built to exact tolerances to ensure effortless installation, smooth actuation, and leak-free performance.
Installation Note
Always isolate incoming hot and cold water supplies before servicing the valve. Carefully remove the outer SmartControl push button and faceplate assembly. Unscrew the securing collar using the appropriate spanner or socket to remove the old 48359000 cartridge from its chamber in the Rapido SmartBox. Clean any limescale or pipe sediment from the brass seating cavity, lightly lubricate the replacement rubber O-rings with WRAS-approved silicone grease, and push the new unit firmly into alignment before securing the retaining nut. (Note: Each push button on a 1, 2, or 3-outlet SmartControl valve is controlled by an independent 48359000 cartridge).
