Cartridge Options for 1/2" Exposed Thermostatic Shower Valve
There are two versions of the thermostatic cartridge for the 1/2" Exposed Thermostatic Shower Valve, which differ in the number of points (ridges or grooves) at the top of the cartridge:
32 Point Thermostatic Cartridge
20 Point Thermostatic Cartridge
The 32 point version of this thermostatic cartridge has been discontinued by the manufacturer and is no longer available. So you will need to purchase the 20 point version of the cartridge and a new compatible 20 point temperature control lever. (Your existing 32 point temperature control lever will not fit the 20 point thermostatic cartridge, because the number of grooves are not equal.)
Thus, you have two replacement cartridge options depending on which version of the cartridge you have.
