Leaking Toilet? It’s Not Just Annoying – It’s Costing You Big Time

How a Leaking Toilet Wastes Water and Money

Toilets are one of the biggest water users in any Brisbane home. But when they leak, they become one of the biggest water wasters too.

A toilet leak is often silent and goes unnoticed, yet it can waste thousands of litres of water each year. Even a slow, hidden leak can add hundreds of dollars to your water bill. If your toilet is running when it shouldn’t be, it’s time to take action.

How Much Water Does a Leaking Toilet Waste?

• A leaking toilet can waste between 200 to 700 litres of water per day.
• That’s over 200,000 litres per year – enough to fill an entire swimming pool!
• Even a slow leak can increase your water bill by hundreds of dollars annually.

Signs Your Toilet is Leaking

• Constant Running Water – If you hear water running when the toilet hasn’t been flushed, you have a leak.
• Water Trickling into the Bowl – Look inside the bowl for small streams of water running down the sides.
• Damp Floor or Mould Growth – A leak at the toilet base can cause dampness or mould.
• High Water Bills – An unexpected increase in your bill is often a sign of a hidden leak.

Common Causes of Toilet Leaks

1. Worn Flapper Valve

The flapper valve seals the flush tank. Over time, it can deteriorate, allowing water to continuously seep into the bowl.

2. Faulty Fill Valve

A broken fill valve can cause your tank to refill constantly, leading to excessive water use.

3. Loose or Worn Seals

Leaks around the base of the toilet are often due to a worn wax ring or loose bolts.

4. Cracked Toilet Tank or Bowl

Hairline cracks can cause slow leaks that worsen over time.

How to Fix a Leaking Toilet

1. Check for leaks – Add a few drops of food colouring into the tank. If the colour appears in the bowl without flushing, you have a leak.
2. Replace the flapper valve – This is a simple and inexpensive fix.
3. Tighten or replace seals – If you notice water around the base, replacing the wax ring may be necessary.
4. Call a plumber for persistent leaks – If you’re unsure or the problem persists, get professional help.

Why You Shouldn’t Delay Repairs

• Reduces Water Bills – A repaired toilet stops unnecessary water waste.
• Prevents Damage – Leaks can lead to mould growth and structural damage.
• Conserves Water – Brisbane faces occasional water restrictions, so every drop counts.

Final Thoughts

A leaking toilet isn’t just a minor issue—it’s an expensive problem that wastes water and increases your bills. Regularly check your toilet for leaks and fix any issues as soon as they arise.

If your toilet is leaking, act fast to save water and avoid unnecessary costs.
