Why Does My Toilet Keep Running? | Causes and Solutions

A constantly running toilet is not just an annoyance—it can lead to higher water bills, wasted resources, and potential damage to your plumbing system. Whether you’re a homeowner, tenant, or landlord, understanding the causes of a running toilet and how to fix it promptly is essential. This guide outlines the most common reasons toilets keep running, how to address them, and how Fraser Bond supports landlords and property owners with responsive property maintenance services.

Common Causes of a Running Toilet

1. Faulty Flapper Valve

• The flapper controls water flow from the tank to the bowl.
• If it’s worn, misaligned, or damaged, it may not seal properly, causing continuous water flow.

Solution: Inspect the flapper for wear or debris. Replace if necessary—this is often an inexpensive, DIY repair.

2. Float Height Issues

• The float mechanism controls the water level in the tank.
• If the float is set too high, water overflows into the overflow tube, causing the toilet to run continuously.

Solution: Adjust the float level using the screw or adjustment clip to lower the water level.

3. Refill Tube Problems

• The refill tube replenishes water in the bowl after flushing.
• If it’s inserted too far into the overflow tube, it can create a siphon effect, causing water to run.

Solution: Reposition the refill tube above the overflow tube, securing it with a clip if needed.

4. Worn or Faulty Fill Valve

• The fill valve controls the water flow into the tank.
• Over time, it may fail to shut off properly, leading to constant filling.

Solution: Replace the fill valve with a compatible model, especially if the mechanism is outdated or corroded.

Consequences of a Running Toilet

• Increased Utility Bills: A running toilet can waste hundreds of litres per day.
• Water Damage Risk: Prolonged leaks can damage floors and ceilings, particularly in multi-unit properties.
• Tenant Complaints: For landlords, unresolved plumbing issues can lead to legal obligations and tenant dissatisfaction.

When to Call a Professional
