If water is uncontrolled or approaching electrical equipment, prioritise safety and call a plumber. The guidance below is general and does not replace an inspection.

Understanding the issue

The button, cable, pneumatic connection or internal flush mechanism may be involved. The correct part depends on the cistern model. A visible button that fits the opening may still be incompatible with the mechanism.

Before arranging the visit

Send the accessible button and cistern details rather than ordering from appearance alone.

Choosing the appropriate plumbing visit

We check the visible fault, isolation, pipe condition and access before agreeing the repair scope. Our toilets & cisterns page explains the related work and how an assessment is arranged.

Where the findings point to toilet flush valve replacement, read the toilet flush valve replacement service details before discussing the repair scope. The actual fitting and access determine the work needed.
