Why Your Toilet Keeps Running
A toilet that runs on and on is almost always one of three tired parts inside the cistern, and none of them is a big job for a licensed plumber. If your toilet keeps running, the usual culprits are an inlet valve that won't close, a flush valve seal leaking into the bowl, or a water level above the overflow.

The suburb's housing stretches from 1960s builds through the 2000s estates, so a single street can hold an old float-valve cistern next to a modern dual-flush one. We cover Eatons Hill and the suburbs around it.
The Three Causes of a Running Toilet
Three faults explain nearly every case: the inlet valve failing to close, the flush valve seal passing water, or the level sitting past the overflow. Each one announces itself differently, which helps you narrow it down before anyone arrives.
Listen and watch for these signs:
Hissing after the refill
Noise that carries on once the cistern has refilled points to an inlet valve that isn't shutting off.
The cistern refills itself
A cistern that tops itself up every few minutes with nothing flushed, or a trickle inside the bowl, points to a leaking flush valve seal.
Water escaping the overflow
A drip from the overflow pipe outside means the cistern fills past its level, so the float or the inlet valve needs attention.
Census figures put 77.8 per cent of Eatons Hill homes at four bedrooms or more, with average household size at 3.1, so the cisterns in these family bathrooms clock up plenty of flushes. Wear shows up earlier than the house's age suggests.
Slow, Partial or No Refill After a Flush
A cistern that won't fill usually means an inlet valve that's worn or gummed up, a float riding low, or a stop tap left half turned. Check that the stop tap at the wall behind the toilet is fully open before blaming the parts.
There's a fourth possibility worth knowing. When water runs but the cistern stays low, the flush valve's seal is probably letting it out as fast as it arrives, so the level never climbs.
A weak refill and a running cistern can share the same root cause. Both trace back to the valve gear that controls water in and water out, which is why a plumber usually checks the two together.
Check for a Silent Leak With Food Colouring
A simple colour test settles whether water is slipping past the seal, and it costs nothing:
- Stir a splash of food colouring through the cistern water.
- Leave it alone without flushing and give it time.
- Colour in the bowl means the cistern is losing water past the seal.
- Once you've read the result, flush; food colouring leaves no stain on ceramic.
- If the bowl stays clear, the seal is holding, and the inlet valve and the level are your next checks.
If there's no colouring in the house, dry toilet paper does a similar job. Lay a sheet at the bowl's rear edge, above the waterline; it should stay dry unless water is creeping down the pan.
Which Cistern Parts a Home Owner May Replace
The QBCC lists three cistern parts as unregulated work that anyone with the appropriate knowledge and skill may repair or replace:
- the drop valve washer
- the float valve washer
- the suction cup rubber
No licence, no approval and no report are needed for those three, though the work still has to reach the standard the legislation and codes set. Every other toilet repair sits in the minor work category, which a QBCC licensee has to carry out. Those jobs need neither a permit nor a Form 4.
Rentals follow the tenancy rules. Queensland tenancy law puts the owner or manager in charge of keeping the premises in good repair; the tenant has to report the fault as soon as possible.
Does the Water Utility Cover a Running Toilet
No, it doesn't. Unitywater's concealed leak adjustment excludes cisterns, along with dripping taps, hot water systems and similar appliances. Leaks on the property side are the owner's to fix, and the water they waste lands on the owner's bill too.
When to Call a Plumber
Ring a licensed plumber when the dye test shows colour, when the cistern keeps refilling itself between flushes, or when the overflow pipe drips outside. Anything past the three unregulated washers belongs to a licensee, and our toilet repairs service handles the rest.
Rentals have their own clock. A repair the tenancy Act doesn't list as an emergency counts as routine, and it has to happen within a reasonable time after the tenant reports it.
Running Toilet Questions From Eatons Hill Homes
Call (07) 3523 7121Which toilet cistern parts can I replace myself?
Three, in the QBCC's wording: drop valve washer, float valve washer and suction cup rubber. A householder may swap those without a licence, though the result still has to meet the standard the codes set. Every other cistern repair is a licensed plumber's job.
Will Unitywater cover a running toilet in Eatons Hill?
No, it won't. Unitywater's concealed leak adjustment excludes water a cistern wastes, so no reduction is available here. The property owner holds primary responsibility for leaks on their side and carries the cost of the water lost.
What is the overflow in a toilet cistern?
The overflow is the outlet that lets surplus water leave the cistern instead of spilling onto the floor. When the inlet valve won't shut off or the float rides too high, the water climbs to the overflow and runs out through it.
Who fixes a running toilet in an Eatons Hill rental?
Queensland tenancy law makes the owner or manager responsible for keeping the rental in good repair, and the tenant should tell them promptly. Anything the Act doesn't treat as an emergency is routine and is due within a reasonable time. The emergency list names a blocked or broken toilet, not a running one.
