How Does Your Toilet Actually Work?
Before you start poking around with tools, it helps to know what’s going on inside that porcelain throne. Most Aussie toilets these days use a dual-flush system, which is ideal for saving water and still getting the job done. When you hit the flush button, the flapper valve lifts, sending water from the cistern into the bowl. That rush of water creates a siphon effect through the S-bend, whisking waste away before the cistern refills via the fill valve.
Here are the main parts you’ll run into:
- Cistern (the tank at the back)
- Bowl
- Flush valve
- Fill valve
- Flapper
- Pan seal at the base
Knowing these basics makes it way easier to figure out what’s gone wrong and whether you can fix it yourself.
The Most Common Toilet Problems in Bayside Homes (and What to Do About Them)
1. Blocked or Clogged Toilets
Nothing ruins your day like a blocked toilet. It’s the most common (and most dreaded) plumbing issue in Aussie homes. Usually, it’s caused by too much toilet paper or flushing things that aren’t meant to go down.
- DIY Fix: Grab a proper toilet plunger (the kind with a flange, not just a flat cup). Make a tight seal over the drain and plunge up and down with some muscle. Still blocked? Try a toilet auger, as it can reach deeper and break up stubborn clogs.
- When to Call a Plumber: If you think something weird (like a toy) is stuck, or if the blockage just won’t budge, it’s time to call a pro. Forcing it can make things worse and mess up your whole sewer line.

2. Running or Constantly Filling Toilet
That never-ending sound of running water? Not only is it annoying, but it’s also costing you money. Usually, the flapper isn’t sealing right, so water keeps sneaking from the tank into the bowl, making the fill valve work overtime.
DIY Fix: Pop the lid off the cistern and watch what happens when you flush. If the flapper looks worn or crusty, swap it out (they’re easy to find at Bunnings). Also check that the water isn’t overflowing back into the bowl. If it is, you might need to adjust or replace the fill valve.
When to Call a Plumber: If a new flapper doesn’t fix it, or you’re not keen on fiddling with the cistern, call in a pro to sort it out quickly.
3. Weak or Incomplete Flush
Is your toilet just not flushing as it used to? You’re not alone. This can happen if the cistern water level is too low, the inlet holes under the rim are blocked, or your home’s water pressure is off.
DIY Fix: Check that the water in the cistern reaches the marked line. If not, adjust the float or fill valve. Next, look under the rim for clogged holes. Make sure to clear them out with a bit of wire or an old toothbrush.
When to Call a Plumber: If the flush is still weak, you might have bigger issues with your plumbing vents or water pressure. Time to call the experts.
4. Toilet Leaks Around the Base
Spotting water around the base of your toilet? Don’t ignore it! The usual culprit is a busted pan seal, which keeps water from leaking out where the toilet meets the drain. Leave it too long, and you could be looking at water damage, mould, and even structural problems.
DIY Fix: Replacing the pan seal means taking the whole toilet off the floor — not a job for the faint-hearted. You’ll need to shut off the water, disconnect everything, remove the old pan seal, fit a new one, and carefully reseat the toilet.
When to Call a Plumber: Honestly, most folks are better off letting a pro handle this one. Ezy-Plumb can swap out your pan seal and make sure everything’s sealed up tight.

5. Wobbly or Loose Toilet
If your toilet rocks when you sit down, it’s not just uncomfortable; it could mean the installation’s off. Over time, this can break the pan seal and lead to leaks.
DIY Fix: First, check if it’s just the seat — tighten the seat bolts if needed. If the whole toilet is wobbly, carefully tighten the bolts or screws at the base (but don’t go overboard, or you’ll crack the porcelain).
When to Call a Plumber: If tightening doesn’t help, or the floor feels soft, get a plumber to check the flange and the floor for damage.
6. Sweating or Condensation on the Tank
Melbourne summers can get humid, and sometimes you’ll see water droplets forming on your toilet tank. It might seem harmless, but over time, that moisture can damage your floor and make things slippery.
DIY Fix: Keep your bathroom well-ventilated. Run the fan, leave the door open, and make sure your air con is working.
When to Call a Plumber: If the problem won’t go away, a plumber can suggest other fixes.
7. Phantom Flushes
Ever heard your toilet flush itself when nobody’s around? That’s a phantom flush, and it means water is leaking from the cistern into the bowl, making the fill valve kick in every so often. It’s a sneaky water waster!
DIY Fix: Put a few drops of food colouring in the cistern and wait 15–20 minutes. If the colour shows up in the bowl, you’ve got a leak, usually a worn flapper. Replace it and check the flush valve seat for damage or mineral buildup.
When to Call a Plumber: If you’ve swapped the flapper and still hear phantom flushes, call a pro to check for deeper issues.
8. Low Water Level in the Bowl
If your toilet bowl water is always low, it could be a cracked bowl, a blocked vent, or other major drainage issues.
DIY Fix: Clear out any debris and make sure water is flowing where it should.
When to Call a Plumber: Sometimes low water means venting issues or cracks you can’t see. If you’re stumped, get a plumber to take a look.

Water Efficiency and Aussie Standards
All toilets sold in Australia have to meet the Water Efficiency Labelling and Standards ( WELS) scheme. This helps you compare water usage — look for the star rating (up to 6 stars) on the label.
To pass WELS, the average flush (one full flush and four half-flushes) can’t use more than 5.5 litres. Modern dual-flush toilets usually use 3–4.5 litres for a full flush and 3 litres for a half, which is a massive improvement over old single-flush models that could use up to 12 litres each time!
If your toilet is ancient and always causing trouble, upgrading to a WELS-compliant model is a smart move. Swapping out an old single-flush for a 4-star toilet can save a family of four about 50 kilolitres of water and $148 a year — plus it’s better for the planet.
Pro Tips for Preventing Toilet Trouble
Want to avoid those emergency calls and keep your toilet running smoothly? Here’s how:
Only flush the three P’s: poo, pee, and toilet paper. Wet wipes (even flushable ones), sanitary products, cotton buds, and dental floss are all no-gos as they’ll clog your pipes in no time.
Keep the lid down: This stops curious kids and pets from dropping things in the bowl (trust us, it happens more than you’d think).
Clean regularly: Use the right cleaning products and pay attention to the inlet holes under the rim — mineral buildup here can mess with your flush.
Inspect the cistern: Every few months, take a peek inside for signs of wear, rust, or mineral deposits. Catching problems early is key.
Check for leaks: Do the food colouring test at least twice a year to spot sneaky leaks.
Don’t ignore small issues: A little leak or a running toilet can turn into a big, expensive problem if you let it slide.
The Importance of Licensed Plumbers
In Victoria, all plumbing work must be carried out by licensed plumbers who comply with strict regulations and standards. It’s illegal for licensed plumbers to install non-compliant products, and all installations must have both WaterMark certification and WELS water rating labels.
When you hire a licensed plumber like Ezy-Plumb, you’re ensuring that repairs and installations meet legal requirements, use approved materials, and come with appropriate warranties and guarantees. This protects both your investment and your home’s plumbing system integrity.
