The Grohe Ladylux faucet contains a cartridge valve system. This cartridge has valves that operate both hot and cold water flow. Often when the faucet leaks or does not dispense the right temperature water, this part needs replacing. Worn out seals or cracked rubber gaskets lead to leaking and inconsistent flow. The replacement process requires a cartridge kit and about a half hour of your time.
