The Grohe 45887000 3/4" Quarter Turn Flow On/Off Cartridge (Clockwise Open) is a genuine Grohe replacement cartridge designed for taps and valves that use a 3/4" ceramic disc flow mechanism with a left-hand (anti-clockwise close) quarter turn action. It restores smooth water on/off control where the original cartridge has become worn, stuck, or leaking.
This flow cartridge fits into compatible Grohe valve or tap bodies to regulate water flow by turning the handle through a 90° (quarter turn) arc. Replacement is typically required when the existing cartridge allows dripping, fails to shut off completely, is stiff to operate, or shows internal wear affecting performance. The cartridge features ceramic sealing disks for durable, low-wear operation.:contentReference[oaicite:0]{index=0}
Before installation, isolate the water supply. Remove the handle and trim to access the old cartridge. Pull out the worn cartridge and insert the Grohe 45887000 unit in the correct orientation. Reassemble the handle and trim and test water flow for smooth on/off control and proper shut-off.
