Summary
Roca A505123503 Loft Shower Column Flow Cartridge - Compatible Replacement
This is a compatible replacement for the Roca A505123503 flow-control cartridge used in Loft shower columns. It is intended for installations requiring this specific cartridge reference.
The cartridge works inside the shower valve to control water flow and shut it off when the handle is closed. It is a flow-control headwork, not a thermostatic temperature-control cartridge.

Before Ordering
Check the original cartridge reference and compare its spindle profile, spline count, mounting thread, sealing arrangement and closing direction with the replacement. The Loft name alone does not establish fitment, and cartridges should not be selected by appearance or partial dimensions alone.
Common Symptoms of Failure
Persistent dripping from the shower head when the shower is turned off can indicate that the flow cartridge is no longer sealing correctly. Replacing a faulty cartridge can restore shut-off where the cartridge is the cause of the leak; check the source of the fault before ordering.
Installation Notes
Isolate the water supplies before removing the existing cartridge and follow the shower manufacturer's servicing instructions. Apply a thin coating of suitable silicone grease to the cartridge O-rings and bottom seal during installation.
