DORNBRACHT, 9021100110090, AUTOMATIC DIVERTER PISTON MECHANISM

Primary Function: Replacement diverter for wall-mounted tub and shower mixers.

Compatible Faucet Series: It is designed specifically for high-end Dornbracht collections, including:

• Tara (specifically the 890 series)

• Tara Classic (880 series)

• Belle de Jour (330 series)

• Dreamworks (470 series)

• Teuco (690 series)

Placement: This piston sits inside the diverter housing of the mixer body. If your shower is "leaking" from the tub spout while the shower is on, or if the diverter knob won't stay up, this is the part that usually needs replacing.
