How to Replace the Shroud Kit on a Aqualisa Aquavalve 405 (UK)

Replace the concealing plate and shroud on the Aqualisa Aquavalve 405 where limescale has locked the temperature handle.

Undo the two handle grub screws (2.5 mm hex on most Aqualisa models). Lift the shroud off — do not lever, it cracks.

Fit new O-rings between the wall plate and shroud to keep the IP54 rating.

Balance hot and cold to within 0.5 bar. Run the Aqualisa Aquavalve 405 at max flow for 3 minutes.

Verify max outlet temperature stays below 46 °C per BS EN 1111 by shutting off cold and reading the outlet.
