Cistern Mechanism Repair

What cistern mechanism repair covers

Cistern faults are often caused by worn or misaligned internal components. This service resolves the issue at source and leaves the toilet working as it should.

• Diagnosis of common cistern faults, including running water, slow filling and poor flush performance
• Isolation of the water supply and safe draining of the cistern where needed
• Repair or replacement of faulty parts such as fill valves, flush valves and syphons
• Adjustment of floats and settings to prevent overfilling and reduce noise
• Checks for leaks around the inlet, outlet and overflow path
• Functional testing to confirm correct shut-off, refill and flush action

When this service is most useful

Book a cistern mechanism repair if you notice any of the following:

• Water constantly running into the pan
• The cistern takes a long time to refill or does not refill fully
• A weak flush, partial flush, or the handle feels stiff or loose
• Intermittent hissing, dripping, or the toilet refilling by itself
• Water around the base that you suspect is coming from the cistern connections

What happens during the visit

The work starts with a quick assessment to identify whether the issue is with the fill side (refill), the flush side (discharge), or an adjustment problem. The water is isolated, the cistern is opened, and the mechanism is repaired or swapped for a suitable replacement part. The system is then tested through multiple flush cycles to confirm reliable operation and no ongoing seepage.

Aftercare and ongoing value

Once the repair is complete, you will know what caused the fault and what to watch for in future. Where appropriate, the settings can be fine-tuned to improve shut-off and reduce unnecessary water use. If a repeat issue is likely due to condition of the cistern fittings, you will be given clear options for the next step.
