Ultra ZSPSPR75 On/​Off Flow Cartridge for A343 Valve

SUMMARY

Ultra ZSPSPR75 Quarter Turn On/Off Flow Cartridge for A343 Jet Shower Panel

The Ultra ZSPSPR75 is a quarter-turn on/off flow cartridge for the A343 Jet thermostatic shower panel, also known as the Hudson Reed Thermostatic Jet Dream Shower.

It controls water flow and shut-off, while a separate thermostatic cartridge regulates the shower temperature. Persistent dripping from the shower head after the flow control is turned off can indicate a worn or damaged flow cartridge. Confirm the cause of the leak before replacing the part.

Before Ordering

Check the A343 model code and compare the removed cartridge's body shape, seal position, total length, lower thread, spline count and closing direction with the details above. The 20.6mm measurement is the lower thread diameter. Check the complete cartridge rather than relying on a single measurement.

Installation Note

Isolate the water supplies before removing the cartridge. Clean the cartridge seating area and lightly lubricate the rubber seals with suitable silicone grease during fitting. Check for leaks and confirm that the flow control opens and closes correctly after restoring the water supply.
