Before You Order Check

Confirm that the mixer is marked 34333000 and determine whether the fault affects temperature regulation, flow shut-off or backflow protection. The 47439000 is the standard thermostatic cartridge shown for this mixer. The 47175000 is a reverse thermostatic cartridge intended for installations with reversed hot and cold supplies and should not be selected unless that supply arrangement has been confirmed.
