Crosswater OEMSC50T20 Thermostatic Cartridge

SUMMARY

Crosswater OEMSC50T20 20 Spline Thermostatic Shower Valve Cartridge

The Crosswater OEMSC50T20 is a thermostatic shower cartridge associated with the SC50-T20 20-spline cartridge family used in selected older Crosswater thermostatic shower mixer valves. The cartridge regulates the mixing of hot and cold water to maintain the selected showering temperature.

A worn or faulty thermostatic cartridge can cause fluctuating water temperatures, insufficient hot water, difficulty adjusting the temperature or stiff temperature controls. Replacing a faulty cartridge can restore normal temperature regulation when the cartridge has been correctly identified.

Important Checks Before Ordering

The SC50-T20 is the 20-spline design and must not be confused with the SC50-T32 32-spline cartridge. Crosswater also used different thermostatic cartridges in later shower valve generations, including CA43-102 and CA43-059 references. A matching shower model name alone does not establish the correct cartridge. Confirm the production version and compare the removed cartridge before purchasing.

Check whether the problem is caused by the thermostatic cartridge before replacing it. Unstable temperatures or a stiff temperature control may indicate thermostat wear, limescale or restricted supplies. Water dripping from a shower head or spout after the valve is turned off can instead indicate a faulty flow or diverter cartridge.

Installation Information

Isolate both hot and cold water supplies before removing the shower controls and cartridge. Inspect the retaining components and valve housing, clean away accumulated debris and check the condition of the sealing surfaces. Follow the valve manufacturer's instructions for installation and temperature-stop calibration. Use a suitable silicone-based plumbing grease on the cartridge O-rings where appropriate.
