Water Tight Canberra plumber replacing Caroma outlet valve in Dickson bathroom.

When a Dickson home owner noticed their toilet constantly running, they turned to Water Tight Canberra for help. What seemed like a minor annoyance was actually wasting hundreds of litres of water every day — but with prompt service and expert repair by our licensed plumber Bodie, the problem was quickly and efficiently resolved.


Problem

The customer contacted our plumber Canberra team after spotting a steady flow of water into the toilet bowl long after flushing — a clear sign of a faulty outlet valve. These silent leaks are among the most common household plumbing issues in Canberra, often going unnoticed until water bills start to rise.

Beyond wasted water, a leaking cistern can cause mineral build-up, wear out seals, and place unnecessary strain on inlet and outlet components. Left unaddressed, that “always-running” sound can turn into a full cistern failure requiring replacement of both valves and internal fittings.

This was the first service call to the Dickson property, so we approached it as a fresh opportunity to assess the system thoroughly.


Assessment

Upon arrival, Bodie, one of Water Tight Canberra’s highly skilled plumbers, carried out a full plumbing safety inspection of the home. During the test, he confirmed the outlet valve had failed, allowing water to continuously trickle from the cistern into the pan.

While inspecting the toilet, Bodie also noted that the inlet valve was nearing the end of its service life, but still operating within acceptable limits. The customer chose to proceed with just the outlet valve replacement and monitor the inlet valve’s performance in the coming months.

This targeted repair approach delivered a cost-effective result without unnecessary component replacements — part of Water Tight Canberra’s transparent and customer-first service philosophy.


What We Did

Bodie isolated the water supply and removed the faulty components before installing a new Caroma M5 Quietflow Outlet Valve (Version 2), supplied through Reece Plumbing Braddon.

This valve model was selected for its:

  • Quiet operation and high efficiency.
  • Durability and precision sealing, compliant with Australian Standard AS/NZS 1172.
  • Compatibility with most modern dual-flush cisterns.

Once installed, Bodie adjusted the flush height and refit the cistern lid, ensuring both full and half flush functions operated smoothly. The system was tested several times to verify a complete shut-off with no residual flow into the bowl.

The work was clean, efficient, and completed within the scheduled appointment window — reflecting our reputation for reliable, timely plumbing service in Canberra.

Fantastic, timely service. Highly recommend.

That short, powerful review from the customer says it all.


Materials & Standards

All components were Australian Standard-compliant and sourced from Reece Plumbing, ensuring quality and longevity:

  • Caroma M5 Quietflow Outlet Valve V2 – advanced seal design for quieter and more efficient flushing.
  • All seals, washers, and internal fittings pressure-tested before completion.

The installation was carried out in accordance with AS/NZS 3500 for plumbing and drainage systems, and documented as part of the property’s unit plumbing safety inspection report.


Results

Before: Toilet continuously leaking into the bowl, wasting water and increasing utility costs.
After: Fully repaired system with a new outlet valve operating quietly and efficiently, saving both water and money.

This small but vital repair not only restored correct function but also extended the lifespan of the toilet system. The homeowner’s feedback perfectly captures the Water Tight Canberra difference:

“Fantastic, timely service. Highly recommend.”

Professional, punctual, and effective — that’s the standard our Canberra clients have come to expect.


Tips

If you notice water running into your toilet bowl long after flushing, it’s time to book a professional inspection for toilet repairs in Canberra.
We recommend:

  • Checking for silent leaks monthly (add food colouring to the cistern — if colour appears in the bowl without flushing, you have a leak).
  • Replacing inlet and outlet valves every 5–7 years to maintain efficiency.
  • Scheduling a plumbing safety inspection every two years to prevent hidden water waste.

Location Notes

Homes and units in Dickson often feature older dual-flush systems that have been in use for more than a decade. Canberra’s hard water accelerates wear on rubber seals and valves, making preventive maintenance critical.
