A worn cistern is usually worth fixing rather than scrapping. For the wider room, our tap and toilet plumbing page maps every job from washers to full replacements.

Inlet Valve, Outlet Valve and Float Explained
Three faults cause most calls: an inlet valve that will not shut off, an outlet valve that lets water escape, and perished seals that leak where the parts join.
Inlet valve
after a flush the inlet valve fills the cistern again and shuts off once the float hits the level set for it. A valve worn or gummed up fills at a crawl or never stops.
Outlet valve
between flushes, a drop valve or flapper holds the water in the cistern. When its washer wears through, water seeps past into the pan, so the cistern keeps needing a top-up and the loo seems to run.
Float
a float set low closes the valve early, leaving the cistern short of water and the flush weak.
Weak or partial flush
low water in the cistern, jet holes beneath the rim blocked with scale, or a jammed flush button are the usual causes.
Cistern not filling
an inlet valve worn or partly blocked, a float riding low, or a partly closed stop tap, provided the water supply is on.
A cistern that will not stop running is usually cured by renewing the inlet valve together with the outlet washer, provided the cistern itself is intact. Our why your toilet keeps running page steps through that fault in full.

Cistern Washers and the Licence Line
The QBCC lists three cistern jobs as unregulated work: the washer inside the drop valve, the washer inside the float valve, plus the suction cup rubber. Anyone with the right knowledge and skill may swap those, though the result still needs to comply with the standards.
Every other toilet repair is minor work that a QBCC licensed plumber handles without a permit or a Form 4. Seals, pan connectors, buttons and cistern swaps all belong to the licensed side.
Renters get extra cover. In a Queensland rental, a broken or blocked loo is an emergency repair under the tenancy rules, so the owner or manager has to arrange it quickly and the tenant reports faults straight away.

Silent Leaks and Sewer Smells
A toilet leaks in three places: the cistern, the base or the supply connection. A failed inlet or outlet valve leaks at the cistern, perished rubbers leak at the base, and the stop tap or its braided hose drips at the supply end.
Water around the base
the pan connector's rubber has perished, the supply line is weeping, or the pan itself has split, provided the floor was dry beforehand.
Water where the cistern sits on the pan
the rubber between the two has failed.
Drips at the supply end
the little stop tap at the cistern, known as a mini stop, or its braided supply hose.
Sewer smell
the rubbers between the pan and the drain have perished or slipped, letting odours back into the room.
One quick check exposes a silent leak: drop some food colouring into the cistern and do not flush, and if colour turns up in the bowl, water is escaping. One flush rinses it away afterwards, since the dye leaves no stain on ceramic.

When a Cracked Toilet Is Past Repair
The cost of a toilet repair is driven by the part that has failed and by any split in the porcelain. Access plays its part too: a cistern and mini stop with room around them are quicker to work on than a tight corner. You get the figure in a fixed quote once the plumber has looked at the job.
Split porcelain is the point where repair gives way to replacement, because no washer fixes a crack. A suite on its fourth set of rubbers can cost less over the years to install new than to keep repairing, and we weigh each case on its own facts.
Any replacement suite needs the WaterMark stamp, which is what lets a licensed plumber install it legally, plus its registration under Australia's water-efficiency labelling scheme (WELS).
Petrie's housing runs from the 1960s hillside subdivisions through to the newest pockets near Moreton Parade, on the former mill land where the university campus now sits inside a priority development area. That spread puts original cisterns and fresh installs on the same run for us.
The older suites are far likelier to need the full valve set renewed rather than a single washer. Drips and stiff handles in the same room are covered under tap repairs, and a fitting past saving gets tap replacement.

Toilet Repair Questions for Petrie Homes
Call (07) 3523 6484What makes a toilet keep running after a flush?
The usual cause is a worn outlet washer: water dribbles past it into the pan, and the inlet valve keeps refilling to make up the loss. An inlet valve that will not shut off does the same thing.
What causes a leak at a toilet base in Petrie?
Usually it is the pan connector's rubber seal, a weeping supply line, or a split in the pan itself. Water where the cistern meets the pan points to the rubber joining them.
Can I fix a leaking toilet myself in Petrie?
Yes, but only inside the cistern. The QBCC's unregulated list covers a cistern's drop valve washer, its float valve washer and its suction cup rubber, and the finished job still has to satisfy the standards. Every other toilet repair needs a licensed plumber.
How much does a toilet repair cost in Petrie?
The price turns on which part has failed, whether the porcelain has split, how easy the cistern and its mini stop are to reach, and how many parts get replaced. The figure comes in a fixed quote after the plumber has seen the job.
Does the water utility cover a leaking cistern?
No, Unitywater's concealed leak adjustment excludes water lost through leaking toilet cisterns, taps, hot water systems and other water appliances, so the owner carries that loss on the bill.
