California Faucets Thermostatic Cartridge - Manual

Instruction to remove calcified cartridge in Thermostatic (TH‐150 / TH‐175) Valve
How to remove a cartridge after the head
becomes separated from the cartridge
body. Close hot/cold service stops.
Remove cartridge head from stuck housing,
open volume control(s) and drain all
residual water in piping.
Screw the cartridge head back into stuck
housing and tighten snug (do not over
tighten).
Remove showerhead from shower arm and
rotate to point upwards (it may be
necessary to remove shower arm reapply
Teflon tape or thread sealant onto thread
to create watertight seal).
If showerhead is ceiling mounted, a
container with pump and flexible tubing
will be needed. A pump style shampoo
bottle and poly flexible tube would serve
well for this type of device.
It is necessary that output device (i.e.
showerhead) be above valve. Open
volume control valve above therm valve
to allow the solution (100% undiluted
white vinegar) to flow down the piping
into valve and breakdown calcium build
up.
