Why Your Toilet Keeps Running
Your toilet keeps running for one of three reasons: a cistern part has failed, and none of them repairs itself. The culprit is usually the inlet valve, the flush valve seal or the water level, and each leaves a sign you can read in minutes.

Kippa-Ring's housing is dominated by the 1960s and 1970s build decades, so a cistern here can hold fittings from several generations of owners. Whatever the age, every job is done by a licensed plumber. This guide from your local Kippa-Ring plumbers steps through the causes, the dye test and the rules on who may do what.
Why the Cistern Never Stops Filling
Three faults explain a cistern that never stops filling: an inlet valve that will not stop, a seal leaking into the pan, or a level spilling through the overflow. After every flush, an inlet valve refills the cistern, and the float tells it when to quit. Each cause leaves its own sign:
Hissing after the refill
Sound carrying on once the cistern has refilled points to an inlet valve that is not closing.
Quiet refills between flushes
A cistern topping itself back up with nobody near the button, or water creeping down the rear wall of the pan, points to the flush valve seal.
A dripping overflow pipe outside
Water escaping the overflow means the cistern fills past its set level, so the inlet valve or float needs attention.
Water Runs but the Cistern Stays Low
A cistern that never fills points to an inlet valve clogged or past its prime, a float riding below its mark, or a stop tap that was never fully opened. Check that the supply to the toilet is fully on before anything else. A stop tap bumped half shut during other work is a common find.
Water running while the level stays low tells a different story. The flush valve's seal may be letting water out as quickly as it arrives, so the cistern can never win. A worn seal on an older single-flush suite often shows up this way, and the fix belongs to a licensed plumber.
What Colour in the Bowl Tells You
Run the dye test this way. Stir several drops of food colouring through the cistern water, keep off the flush button, and give it time. Colour creeping into the bowl means the cistern is losing water into the pan.
Flush once the test has given you an answer. Ceramic bowls come out unstained, and one flush clears the colour completely.
A bowl that stays clear tells you the flush valve is doing its job. Look next at the inlet valve and how the float is set.
No colouring in the cupboard? Rest a dry sheet of toilet paper against the upper back of the bowl, clear of the waterline. Paper that ends up damp means a leak.
The QBCC List of Unregulated Cistern Work
The QBCC names three cistern parts as unregulated work: a suction cup rubber, a float valve washer and a drop valve washer. Anyone with the needed knowledge and skill may repair or replace them, and the result must still meet the standards the codes set.
Past those three parts, toilet work belongs to a QBCC licensee as minor work, and neither a permit nor a Form 4 comes into it. Queensland tenancy law puts two duties on rentals: the owner or manager keeps the place maintained, and the tenant flags faults straight away.
What a Running Cistern Does to Your Water Bill
No, Unitywater's concealed leak adjustment does not extend to water lost through a leaking cistern, nor through leaking taps, hot water systems or other appliances. The property owner fronts leaks on their side of the meter, along with the water those leaks waste.
Every quiet top-up is metered water, so a running cistern tends to show up on the bill before anywhere else. Fixing it early keeps the loss small.
When to Hand the Job to a Plumber
Colour in the bowl, a hiss that will not stop, or a cistern refilling on its own all end the same way: with a booked repair. Our toilet repairs service page covers the full job, from diagnosis to parts.
The price turns on which part has failed, which cistern it lives in, and how easily the unit opens up. You get a fixed quote before any work starts.
Renters should note one wrinkle. The Queensland emergency list for rentals covers blockages and toilets that stop working. A toilet that keeps running is not on it, so the repair is routine and gets done within a reasonable time of the report.
Running Cistern Questions Answered
Call (07) 3523 6484Why is my toilet cistern not filling up?
Usually the inlet valve is worn or blocked, the float sits below its level, or the stop tap is only partly open. If the water runs but the level never rises, the flush valve's seal may be draining water faster than it arrives.
How do I check for a silent toilet leak?
Drop a little food colouring into your cistern water and leave it unflushed. Colour in the bowl means water is getting past the seal, so flush afterwards, because the colouring leaves ceramic unstained. Unitywater recommends this check for household leaks.
Will food colouring stain my toilet bowl?
No, food colouring does not stain ceramic bowls, and one flush afterwards clears it completely.
Does Unitywater cover a running toilet in Kippa-Ring?
No, the utility's concealed leak adjustment leaves leaking cisterns out, along with taps, hot water systems and other appliances, so the loss stays with the property owner.
