How to Replace a Wirquin Pro Air Dual Flush Plate (UK)

Swap a Wirquin Pro Air Dual concealed-cistern flush plate in a UK bathroom. Dual-flush levers, seals, adjustment.

Wirquin

Identify

Confirm your Wirquin frame series — Pro Air Dual 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 Wirquin Pro Air Dual 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 Wirquin Pro Air Dual 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 Wirquin Pro Air Dual fit any concealed frame?
Only Wirquin-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.
