Dornbracht 9090031630090 is a diverter cartridge compatible spare for selected Dornbracht concealed thermostatic shower valves with two-way or two-function volume control. It is used to control outlet selection within the valve assembly and should not be confused with the separate thermostatic cartridge, handle base extension, brass sleeve or cartridge adapter used elsewhere in the same valve.
This spare is also shown as 90.90.03.163.90 and 90 90 03 163 00 90 in Dornbracht-style spare parts information. A common sign of diverter cartridge wear is water passing to the wrong outlet, poor outlet switching, or dripping from a shower head or spout when the shower is turned off or when that outlet should not be selected.
