Before Ordering

Check the valve model and compare the removed cartridge with the product photographs, including its overall length, spindle, seal positions, mesh bands and retention features. Showers marked RM553WC+ require separate cartridge identification before ordering.

Fault Identification

Difficulty adjusting the temperature or an unstable shower temperature can indicate a worn or obstructed thermostatic cartridge. Check the water supplies and valve condition before replacing it. If the Curve RM553WC continues to drip from the fixed head or handset when turned off, inspect the separate CR010NC flow/diverter cartridge as part of the fault diagnosis.

Installation and Servicing

Isolate both hot and cold water supplies before removing the existing cartridge. Follow the servicing instructions for the exact valve model, clean debris from the valve body and lightly lubricate the cartridge seals with suitable silicone grease. After reassembly, check for leaks and correct temperature adjustment, and check the temperature-stop setting where fitted.
