ROCA A525092709 Pair of Cartridges

Summary

Roca A525092709 Half-Turn Ceramic Flow Cartridge Pair for Loft Taps and Mixers

Roca A525092709 is a pair of ceramic flow-control cartridges with 180-degree half-turn operation for the Roca Loft taps and mixers listed below. The set contains two cartridges for use with rotating handle controls.

These cartridges regulate and shut off water flow inside the mixer. In the listed thermostatic shower and bath-shower mixers, they perform the flow-control function rather than controlling the mixed water temperature; the thermostatic cartridge is a separate component.

Before Ordering

Some Loft models changed from cartridge reference 525158509 before October 2006 to 525092709 after October 2006. Check the production version and original cartridge arrangement before ordering; do not assume these references are interchangeable.

Match the exact mixer model and cartridge reference, then compare the original cartridge body, spindle, handle connection, closing direction and sealing arrangement. The Loft range name or an apparent size match alone is not sufficient to identify the correct cartridge. Half-turn describes the operating movement, not the fitting thread size.

Common Failure Symptoms

Persistent dripping from the tap spout or shower head when the control is turned off can indicate worn or damaged flow-cartridge sealing surfaces. Stiff operation or difficulty shutting off the water may also require inspection of the cartridge. On thermostatic mixers, temperature-control faults should be assessed separately rather than assuming that this flow-cartridge pair will resolve them.

Installation Note

Isolate the hot and cold water supplies before removing the existing cartridges. Follow the instructions for the exact mixer, clean the cartridge seating areas and check that the seals are correctly positioned during fitting.
