"Our toilet started leaking at the base, not urgent but was damaging the floor slowly. Alljack found me a local plumber who had availability that week. Wax seal had gone. He replaced it, re-set the pan, left the place clean. Good job."
"Fixed fast, no fuss. Happy."

"Cistern was filling really slowly and making noise. Alljack found someone that week. Working normally now."

The most common toilet fault in Gosford rentals. A hissing sound means water is continuously running into the cistern or past the flush valve into the pan. This wastes 200–500 litres per day and won't stop without replacing the faulty valve.
If you can hear the toilet filling every few minutes with no one using it, the fill valve isn't shutting off at the correct water level — or the flush valve is leaking water into the pan, triggering a constant refill cycle.
A toilet that moves when you sit on it has a failed pan collar or perished foam seal at the floor waste. Left unrepaired, the horn can crack and sewer gas will enter the room. The pan collar needs replacing before it becomes a larger problem.
Water pooling around the base of the toilet pan — especially after flushing — means the wax seal or rubber gasket between the pan and the floor waste has failed. This is a hygiene issue that needs urgent repair.
A toilet that takes multiple flushes to clear, or where water rises before draining slowly, usually has a partial blockage in the pan trap or the sewer line. In older Gosford unit blocks, a blocked shared stack can affect all units on the floor.

Running cisterns are by far the most common toilet call-out for Gosford property managers. Older single-flush toilets installed in the 1980s–90s use plastic inlet valves and rubber seals that degrade over time — and when they go, the water doesn't stop.
Most toilet repairs are completed in a single visit. The plumber shuts off the isolation valve behind the toilet, then diagnoses and fixes the fault:
For concealed cisterns (common in newer Gosford apartments and renovated bathrooms), access is more complex and quotes typically run 30–50% higher due to the additional labour.
Concealed cistern repairs add $100–$200 to the above prices due to access difficulty. Wall-hung toilet suite replacement (popular in newer Gosford apartments) starts at $800 and can reach $1,500 depending on the carrier frame and suite selected.
Running cisterns are the #1 maintenance request from Gosford property managers. The unit blocks on Mann Street, Donnison Street, and along Henry Parry Drive have high concentrations of older single-flush toilets. NSW tenants have the right to request urgent repairs for plumbing faults that waste water — making this a legal obligation as well as a water bill issue.
Toilet repairs in Gosford typically cost $140–$250 for a fill valve (inlet valve) replacement — the most common repair for a running or constantly refilling toilet. A full cistern service including flush valve, inlet valve, and cistern seal runs $200–$320. Full toilet replacement (supply and install, standard close-coupled suite) costs $400–$800. Concealed cistern repairs cost 30–50% more due to access difficulty. With Alljack you get 3 competitive quotes from local Gosford plumbers so you can compare.
Repair if: the cistern mechanism has failed but the pan and bowl are in good condition — new inlet valves, flush valves, and cistern seals are inexpensive. Replace if: the pan is cracked, the toilet is an older single-flush unit (these waste 11–13 litres per flush vs 3–6 litres for a modern dual-flush), the toilet is rocking on the floor waste, or repair costs are more than half the price of a new unit. Many older single-flush toilets in Gosford's rental stock should be replaced with WELS-rated dual-flush suites.
A running toilet is caused by one of two things: a failed fill valve (inlet valve) that doesn't shut off when the cistern is full, causing water to overflow into the pan via the overflow tube; or a failed flush valve (flapper or outlet valve) that allows water to slowly leak past the seal from the cistern into the pan. Both are common in Gosford's older single-flush toilets installed in the 1980s–90s. A running toilet wastes 200–500 litres daily.
Yes. A toilet where the cistern continuously refills wastes 200–500 litres per day, or 70,000–180,000 litres per year. At Central Coast water rates, that adds $150–$400 to your annual water bill. A running toilet in a rental is also a compliance issue — NSW tenants can request urgent repairs for plumbing faults that waste water. Fixing a running cistern with a new inlet valve typically costs $140–$250 and pays for itself in water savings within a few months.
