Why Is My Toilet Constantly Running? Common Causes and Fixes

A constantly running toilet is more than just an annoying sound—it’s a silent water waster that can significantly increase your utility bills in Surrey homes. Many homeowners ignore it until the problem worsens, but in most cases, the fix is straightforward when handled early.

At Guru Plumbing & Heating, we regularly help Surrey homeowners diagnose and repair running toilets quickly and affordably. Below, we break down the most common causes, easy fixes, and when to call a licensed plumber in Surrey.

What Does It Mean When a Toilet Keeps Running?

A toilet that keeps running usually means water is continuously flowing from the tank into the bowl instead of stopping after a flush. This can waste up to 200 gallons of water per day, depending on the severity of the issue.

If you’re dealing with this problem, it’s time to act, especially in Surrey homes with older plumbing fixtures.

Common Causes of a Constantly Running Toilet

1. Worn or Misaligned Flapper Valve

The flapper seals water inside the tank. Over time, it can warp, crack, or fail to sit properly.

Signs:
  • The toilet refills every few minutes
  • Water slowly trickles into the bowl
Fix:

Replacing a flapper is inexpensive, but improper installation can cause repeated issues. A Surrey plumber can ensure the correct size and fit.

2. Faulty Fill Valve

The fill valve controls how much water refills the tank. If it sticks or fails, water keeps flowing.

Signs:

  • Hissing sound
  • Tank overfilling
Fix:

Fill valves often need replacement, especially in hard-water areas like Surrey, where mineral buildup is common.

3. Float Set Too High

If the float is set too high, water spills into the overflow tube nonstop.

Fix:

Adjusting the float may solve the issue—but incorrect adjustments can reduce flushing efficiency.

4. Overflow Tube Problems

Cracks or incorrect positioning of the overflow tube can allow constant water drainage.

Fix:

This typically requires professional plumbing service in Surrey to prevent tank damage.

5. Loose or Deteriorated Chain

A chain that’s too short or tangled can prevent the flapper from sealing.

Fix:

Minor adjustments may work, but worn chains should be replaced.

Can a Running Toilet Increase My Water Bill in Surrey?

Yes, significantly. A constantly running toilet can add $50 to $150 per month to your water bill. Surrey homeowners on metered water feel this impact even faster.

This is why Guru Plumbing & Heating Surrey recommends fixing running toilets immediately rather than waiting.
