How to Replace the Shroud Kit on a Triton T80Z Fast-Fit (UK)

UK guide to swapping the shroud kit in a Triton T80Z Fast-Fit shower valve. TMV2 compliance, part numbers, tools.

Triton

The part

Replace the concealing plate and shroud on the Triton T80Z Fast-Fit where limescale has locked the temperature handle.

Isolate

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

Swap the shroud kit

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

Commission

Balance hot and cold to within 0.5 bar. Run the Triton T80Z Fast-Fit 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.

Frequently asked questions

Chrome or brushed?
The Triton T80Z Fast-Fit kit ships in polished chrome as standard. Brushed finishes carry a -BR suffix.
Wall plate offset?
10–35 mm adjustment on Triton concealed valves — use the shroud packer to hide any tile mismatch.
OEM or aftermarket for Triton?
For TMV2/TMV3 compliance always fit genuine Triton cartridges. Aftermarket voids the T80Z Fast-Fit approval.
