Running toilet repair Sydney homes need most

A running toilet is one of the most common toilet repairs Sydney homes need. Water keeps trickling into the bowl long after the flush, or the cistern hisses as it refills every few minutes.

Why toilets keep running

Worn flush valve seal. Water leaks from the cistern into the bowl, so the cistern keeps topping up.
Faulty inlet valve. The valve doesn't shut off when the cistern is full, so water runs into the overflow.
Both at once. Common in older toilets where every part is the same age.

A plumber for running toilet jobs replaces the failed valve, adjusts the water level and tests it over several flushes.

Check for a silent leak

Not every leak is loud. Put a few drops of food colouring in the toilet cistern and wait 15 minutes without flushing. If colour shows up in the bowl, the flush valve is leaking. If you see it, we can fix running toilet faults in one short visit. It's usually one of the simpler toilet repairs Sydney households can book, and it stops water going down the drain all day.

Toilet cistern repairs and replacement

Most toilet cistern repairs are a single part: the inlet valve, the flush valve, the button or a seal. Fixing a toilet cistern this way is quick and keeps the original toilet in place.

When a replacement cistern makes sense

A replacement cistern is the better option when the cistern is cracked, the parts are no longer made, or the cistern is so old it uses far more water per flush than a modern one. We fit a new toilet cistern to suit your pan where one is available. We quote every cistern replacement Sydney customers ask about only after checking the pan, because not every new cistern fits an old pan.

Ceramic toilet cistern replacement

A ceramic cistern can crack with age or a knock. A cracked ceramic toilet cistern usually leaks slowly at first, then all at once. Ceramic toilet cistern replacement needs the right match for your pan, so we check the model and connections before quoting.

Inwall cistern toilet repairs

Inwall cistern jobs are some of the trickier toilet repairs. Sydney apartments and newer homes use them a lot. An inwall cistern toilet hides the cistern behind the wall, with access through the flush plate. A cistern in wall toilet still has the same valves inside. We reach them through the access panel, so the wall stays as it is. If your bathroom cistern is concealed and leaking, call us before water reaches the wall frame.

Leaking toilet repairs Sydney homes put off

A leaking toilet Sydney homeowners ignore can damage floors and subfloors. These are the leaks we fix most often in toilet repairs Sydney wide:

Leaking at the base. A worn seal or pan connector under the toilet. You'll often see water or staining around the pan.
Leaking from the cistern. A failed seal between the cistern and the bowl, or a cracked cistern.
Leaking at the wall. The connector hose or the stop tap behind the toilet.
A wobbly pan. Loose fixings can break the seal and cause a leak you can't see.

Our leaking toilet repairs Sydney customers book include finding the cause and a test after the repair, so you know the leak has stopped.

Toilet overflowing or toilet bowl stinks?

Toilet bowl overflow

A toilet overflowing after a flush is almost always a blockage in the pan or the drain. Turn off the stop tap behind the toilet and stop flushing. A toilet bowl overflow that keeps happening points to a blocked or damaged drain line. Our blocked toilet page explains how we clear it.

A stinky toilet

When a toilet bowl stinks even after cleaning, the cause is usually a failed seal at the base, a dry trap in a toilet nobody uses, or a sewer vent problem. A stinky toilet is worth a look, because the same seal failure that lets smells out can let water through. Most smell problems are quick toilet repairs. Sydney homes with a second toilet nobody uses often just need the trap refilled and the seal checked.

Toilet replacement Sydney: when a repair won't do

Sometimes the toilet is past saving. Rather than keep paying for toilet repairs, Sydney homeowners with cracked pans, old toilets with no parts available or toilets that leak no matter what are better off with a toilet replacement.

Our toilet replacement and toilet installation Sydney service covers:

Removing and disposing of the old toilet.
Checking the waste connection and water supply.
Fitting the new toilet bowl cistern set, with new connectors and seals.
Testing for leaks and a full flush.

Toilet plumbing replacement goes most smoothly when the new toilet suits the existing waste position, so we check that before you buy. We can supply the toilet or fit one you've chosen.

Toilet repairs Sydney FAQs

How much do toilet repairs cost in Sydney?

It depends on the part. Most toilet repairs Sydney homes need are a single valve or seal. We look first, then give you a fixed price before any work starts.

Can you fix toilet plumbing on the first visit?

Usually, yes. We carry flush valves, inlet valves, seals and common cistern mechanisms in the van, so most toilet repairs Sydney customers book are done in one visit.

How do I know if my toilet cistern is leaking?

Use the food colouring test. A few drops in the cistern, wait 15 minutes, and check the bowl. Colour in the bowl means the flush valve is leaking.

Why does my toilet run all night?

Usually the inlet valve or the flush valve has worn. Both are quick to replace, and we repair toilet running faults like this in one visit most of the time.

Should I repair or replace my toilet?

If the pan and cistern are sound, repair is cheaper. If either is cracked or parts aren't available, replacement is better value. We check the pan, the cistern and the toilet cistern plumbing connections first, so you know which before you spend anything.
