Is this your part?
Pull the handle and escutcheon. The Tempress II cartridge is a white polymer barrel about 3-1/4 in. long with a splined brass stem and a knurled collar, held in the valve by a retainer clip that lifts out. Count 20 splines on the stem.
When to replace it
Water weeps from the spout or showerhead after the handle is closed, temperature surges when a toilet flushes, the temperature creeps during a shower, flow fades, or the handle has gone stiff.

Questions
Does it fit my newer Grohe valve?
It fits Grohe 35 200 series pressure balance valves installed before 2008. It does not fit post-2008 platforms.
Does it fit Grohe thermostatic valves?
No. It is a pressure balance cartridge for single-handle valves only.
The shower runs too hot after the swap. Why?
The rotational limit stop was reset in a different position. Move it back to your old setting.
Is the gasket included?
Yes. The O-rings and body gasket come fitted to the cartridge.
