Spare parts for the Grohe 31179000 Eurosmart Cosmopolitan single lever sink mixer. This chrome kitchen tap is the low-pressure version designed for use with an open or unpressurised storage water heater and uses a three-hose arrangement.
The 31179000 uses a Grohe SilkMove 46 mm ceramic cartridge to control water flow and temperature. Its low swivel tubular spout provides a 140 degree swivel area and the mixer has an adjustable flow-rate limiter.

When an unpressurised storage heater is heating, expansion water may drip from the mixer spout. This is part of the operating principle of an open water-heater installation and should not automatically be treated as a mixer fault. Flow-restricting fittings should not be added downstream where they could interfere with this arrangement.
Confirm that the tap is Grohe model 31179000 and that it is the low-pressure Eurosmart Cosmopolitan version for an open water heater. Do not select parts solely from the 1/2 inch wording in the model name, as the technical drawing shows G 3/8 flexible hose connections.
