A toilet leaking into the bowl is one of the most common plumbing problems around Australian homes, and it can waste a surprising amount of water if left unchecked. The good news? Fixing a toilet leak isn’t complicated, and you can often handle it yourself without calling a plumber in Sydney.
At Fix N Flow, we get many calls about leaking toilets, especially those annoying ones where the water keeps running or dripping into the bowl. In this blog, I’ll walk you through everything you need to know about how to fix a leaking toilet in Australia. We’ll cover causes and step-by-step fixes to stop that drip once and for all.
When water continuously flows from the cistern, leaking into the bowl, here’s what’s usually going on:
The thing is, these leaks happen slowly, making them hard to notice until your water bill increases or you hear that constant drip. A slow water leak in the toilet bowl can waste hundreds of litres of water every day.
A toilet leaking when flushed is obvious. But what if it’s leaking quietly and constantly? Here’s how you can check:
Even when you’re not flushing, a leaking toilet sounds like water is running or dripping. If your toilet keeps making noise, there’s definitely a leak.
This is the classic test. Add a few drops of food colouring to the cistern water and wait 15-30 minutes without flushing. If the colour appears in the bowl, it is an obvious sign that water is leaking from the cistern.
When a toilet leaks into the bowl, it’s usually caused by the flapper, so this guide will mainly focus on its replacement and how you can do it yourself.
Locate the shut-off valve behind your toilet, near the wall. Turn it clockwise until it stops to shut off the water. Then flush the toilet to empty the cistern.
Gently lift the cistern lid and place it somewhere safe where it won’t fall or break. Use a sponge or towel to soak up any leftover water at the bottom of the cistern if needed. Take a close look inside.
Lift the flapper valve slightly. If the water flow stops immediately, the flapper is likely the source of the leak. Look closely for damage. If you spot it, it’s time to replace the flapper.
Turn the water supply back on by twisting the shut-off valve counterclockwise. Let the cistern fill completely. Add a few drops of food colouring to the water in the cistern and wait 15 minutes without flushing. If no colour appears in the bowl, congratulations, your leak is fixed!
Dealing with a toilet leaking into the bowl doesn’t have to be a hassle. With the right tools and a bit of know-how, you can fix the leak yourself, save water, and stop the noise.
The thing is, these small repairs make a big difference for your water bill. If you’re not confident or the leak persists after trying, don’t hesitate to call a professional.
