Crosswater Nova Hot Valve Cartridge (53CR581AS)

SUMMARY

Crosswater Nova Hot Valve Cartridge (53CR581AS)

The Crosswater Nova 53CR581AS hot valve cartridge is a hot-side flow control headwork used in Crosswater Nova bathroom tap brassware. It operates the hot-water control, allowing water to flow when the tap is opened and shutting off the supply when the control is closed.

This cartridge is intended for the hot-water side. A worn or damaged flow cartridge can cause water to continue dripping from the tap or bath spout when the control is turned off. Other possible symptoms include a stiff handle, difficulty shutting off the water completely or inconsistent operation of the hot-water control.

Before Ordering

Crosswater manufactures different cartridges for hot and cold water controls, so it is important to identify the correct side before ordering. The Nova cold valve cartridge is listed separately under part number 53CR581AD. Check the part number on your existing cartridge where available, and compare the overall dimensions, body thread, spindle shape and sealing arrangement with the original part. Similar-looking cartridges may have different fittings or operating characteristics.

Installation and Fault Checks

Before removing the existing cartridge, isolate the water supply and release any remaining pressure. Remove the tap handle and associated retaining components according to the instructions for your particular tap. Inspect the cartridge housing for limescale, debris and damaged sealing surfaces. When fitting the cartridge, ensure that the seals are correctly positioned and that the cartridge is seated properly before tightening. Once installed, restore the water supply and check that the control operates smoothly and shuts off the water without dripping.

If water continues to drip after replacing the hot-side cartridge, check whether the leak originates from the hot or cold supply and inspect the relevant cartridge and sealing surfaces before replacing further components.
