How to Replace a Roca PL7 Duplo Flush Plate (UK)

Swap a Roca PL7 Duplo concealed-cistern flush plate in a UK bathroom. Dual-flush levers, seals, adjustment.

Roca

Identify

Confirm your Roca frame series — PL7 Duplo plates only fit specific in-wall carriers. Look on the inspection window for the frame's date-stamp and part number.

Remove the old plate

Pull the Roca PL7 Duplo plate away from the wall (magnetic or clip-on). Disconnect the two flush levers or pneumatic tubes from the top of the cistern.

Fit the new plate

Adjust the Roca PL7 Duplo lever rods to length. Reconnect, refit the plate. Test full and reduced flush volumes (6 L / 3 L standard UK).

Frequently asked questions

Will the Roca PL7 Duplo fit any concealed frame?
Only Roca-brand frames. Cross-brand fitting rarely aligns.
Do I need to isolate water?
No — the plate is external; you only touch the flush actuators, not the fill valve.
