Leaking Toilets: Causes, Problems, and Solutions

A leaking toilet can be a frustrating and costly issue in any home or business. Even small leaks can waste a significant amount of water and lead to expensive repairs if left untreated. At Burns Heating, we understand the importance of keeping your plumbing in top condition, so here’s everything you need to know about leaking toilets.

Common Causes of a Leaking Toilet

A toilet can leak from different places, and identifying the source is key to fixing the issue. Here are some common causes:

1. Faulty Flapper Valve – The flapper controls the water flow from the tank to the bowl. If it’s worn out or misaligned, it can cause continuous running water.

2. Cracked Tank or Bowl – Even small cracks in the porcelain can lead to leaks over time.

3. Worn-Out Wax Seal – The wax ring that seals the toilet to the floor can degrade, causing water to leak around the base.

4. Loose or Faulty Connections – Water supply lines, bolts, and gaskets can loosen or wear out, leading to leaks.

5. Overflowing or Malfunctioning Fill Valve – If the fill valve isn’t functioning properly, it can cause the tank to overfill and leak through the overflow tube.

Why Fixing a Leaking Toilet is Important

Ignoring a leaking toilet can result in a range of issues, including:

• High Water Bills – Even a slow leak can waste hundreds of litres of water, increasing your utility costs.

• Structural Damage – Water leaks can weaken flooring and walls, leading to costly repairs.

• Mould and Mildew Growth – Persistent moisture creates the perfect environment for mould, which can be harmful to health.

• Potential Health Hazards – Leaks around the base of the toilet can lead to unsanitary conditions and bad odours.

How to Fix a Leaking Toilet

If you notice a leak, here’s a basic guide to troubleshooting and fixing it:

1. Check the Flapper Valve – If your toilet runs constantly, replacing the flapper might be an easy fix.

2. Inspect the Fill Valve – If the tank is overfilling, adjust or replace the fill valve.

3. Tighten Connections – Check the bolts and supply line for any loose connections and tighten as needed.

4. Replace the Wax Ring – If water is leaking from the base, you may need to remove the toilet and replace the wax ring.

5. Look for Cracks – If your toilet has visible cracks in the bowl or tank, it may be time for a replacement.

If you’re not confident in tackling the repair yourself, it’s always best to call in a professional.
