Toilet Repair and Replacement Plumbers in Castle Hill & The Hills District

Fixing a Leaking Toilet  – Why a Professional Service Matters

A leaking toilet cistern is a common issue in many homes, often caused by the gradual wear and tear of rubber seals and internal components. Over time, these ageing seals can allow water to trickle onto the bathroom floor or constantly run into the bowl via the overflow valve—leading to higher water bills and ongoing frustration.

While some homeowners attempt a DIY fix, the reality is that repairing a leaking cistern properly requires:

• The right plumbing tools and replacement parts
• Technical knowledge of flushing mechanisms
• Time and patience to do the job properly

A quick patch-up may stop the leak today, but without inspecting and servicing the entire system, the problem often comes back. That’s why our team at Hills District Plumbing takes a comprehensive approach.

What’s Included in a Professional Toilet Cistern Service?

We provide a complete cistern service that ensures lasting results. Our experienced plumbers check every part of your toilet’s flushing system and proactively replace worn components.

Our standard cistern service includes:

• Replacing the outlet rubber seal at the base of the cistern
• Replacing worn inlet valve seals to stop internal dripping
• Installing a new tap washer and o-ring on the water supply connection
• Testing and adjusting float levels and flush strength
• Inspecting the cistern and pipework for cracks or hidden leaks

This thorough approach means fewer future breakdowns, reduced water usage, and long-term peace of mind.

If your toilet is:

• Leaking water onto the floor
