Roca A525012503 Thesis Cartridge

SUMMARY

Roca A525012503 Thesis Diverter Cartridge for Bath Shower Mixers

The Roca A525012503 is a diverter cartridge used in selected Roca Thesis-T, Targa-T and T-5000 / Panama-T thermostatic bath/shower mixers, as well as the Evolution A2H0416000 hydromassage thermostatic column.

This cartridge operates the outlet-selection mechanism, directing water to the selected outlet. In the specified bath/shower mixers, it forms part of the diverter and flow-control arrangement. It is separate from the thermostatic cartridge that regulates the mixed water temperature.

Before Ordering

Check the exact mixer or column reference and confirm that its parts diagram specifies A525012503. Compare the original cartridge's spindle, body and sealing arrangement with the product photographs. The range name or cartridge diameter alone is not sufficient to identify the correct part. Check whether your repair also requires a retaining nut or separate seals before ordering.

Fault Finding

Poor outlet switching, water passing to an unselected outlet or persistent dripping from the shower head or bath spout after the control is turned off are reasons to check the diverter and its seals. Confirm the source of the fault before changing the cartridge. This is not the thermostatic temperature-control cartridge.
