Spare parts for the Grohe 31212003 Concetto single-lever sink mixer 1/2 inch, a chrome low-pressure kitchen tap designed for use with an open water heater. The mixer combines single-lever flow and temperature control with a high swivel spout and pull-out outlet.

Grohe spares available for this mixer include the low-pressure cartridge, tap hose, mounting set and service tool listed below. Check the production period and existing spare part code before ordering because GROHE has revised some internal parts while retaining the 31212003 mixer code.
