Ideal Standard A954703NU Cartridge for Trevi Ceramix Alto Shower Valves

Summary

Ideal Standard A954703NU Single Click Lever Cartridge Replacement for Trevi Ceramix Alto Showers and Taps

Ideal Standard A954703NU is a single-click lever cartridge for the Trevi Ceramix Alto built-in manual shower valve and the specific basin and bidet mixers listed below. It is the internal cartridge operated by the mixer lever, not a thermostatic cartridge.

The cartridge controls water flow and shut-off. In the listed single-lever mixers, the lever also adjusts the hot and cold water mix. A worn or damaged cartridge can cause persistent dripping from the shower head or tap spout when turned off, stiff lever movement or difficulty controlling the flow.

Before Ordering

Check the exact shower valve or mixer model and compare the existing cartridge's overall shape, metal lever, base connections, locating points and sealing arrangement with the product photographs. The dimensions are identification aids, not proof that another cartridge of the same diameter will fit. Do not select this part from the Ceramix or Sandringham range name alone.

Fitting Notes

Isolate both hot and cold water supplies before removing the cartridge. Follow the servicing instructions for the exact mixer or shower valve, remove any old cartridge seals left in the housing and check that the new cartridge is correctly located before securing it. Inspect the existing handle, retaining screws and surrounding seals for damage while the assembly is accessible. After reassembly, restore the supplies and check for leaks, smooth operation and complete shut-off.
