Why Is My Toilet Water Running? Common Causes and Fixes

If you’ve ever experienced the annoyance of a toilet that just won’t stop running, it’s time to act. This common plumbing issue can be both irritating and costly, leading to unnecessarily high-water bills. In this blog, we’ll explore the common causes of a running toilet and how MK Handyman London, your go-to bathroom handyman for toilet repairs, can help you fix the problem efficiently.

Why Does Toilet Water Keep Running?

A running toilet occurs when water continuously flows from the tank into the bowl. This not only wastes water but can cause damage to your plumbing system if left unchecked. Understanding the underlying causes of this issue is crucial for both short-term fixes and long-term solutions.

Common Causes of a Running Toilet

1. Flapper Valve Issues

The flapper valve is a rubber component that sits at the bottom of the toilet tank. If it’s worn out or misaligned, water may leak from the tank into the bowl, causing the toilet to run continuously. Regularly checking the flapper valve and replacing it, when necessary, can prevent this problem.

2. Float Problems

The float controls the water level in the tank. If it’s set too high, water may overflow into the overflow tube, leading to a running toilet. Adjusting the float arm or replacing the float can resolve this issue quickly.

3. Faulty Fill Valve

The fill valve controls the flow of water into the tank after a flush. If it’s malfunctioning, it may not shut off properly, resulting in a running toilet. A skilled bathroom handyman can help diagnose and replace a faulty fill valve.

4. Clogs in the Overflow Tube

If the overflow tube is clogged, it can prevent proper water flow and lead to continuous running. Regular maintenance can help prevent this issue from arising.

5. Worn-Out Parts

Over time, various components of your toilet may wear out. This includes the flapper, fill valve, and other internal parts. Regular inspections by a bathroom handyman can help identify worn-out components before they become a major problem.

Why Fix It Quickly?

Ignoring a running toilet can lead to several pain points, including:

  • Increased Water Bills: A running toilet can waste hundreds of gallons of water each month, significantly increasing your water bill.
  • Potential Damage: Continuous running can cause wear and tear on your plumbing, potentially leading to more serious issues down the line.
  • Hygiene Concerns: Stagnant water can lead to bacteria growth, which isn’t ideal for your bathroom environment.

Quick Fixes Before the Bathroom Handyman Arrives

While waiting for your bathroom handyman to arrive, there are several quick fixes you can try to temporarily address a running toilet. These solutions can help minimise water waste and provide you with some immediate relief:

1. Adjust the Float

Lift the lid off the toilet tank and locate the float. If it’s a ball float, gently bend the arm downwards. If it’s a cylinder float, adjust the screw on top to lower the float. This can help stop the water from overflowing into the overflow tube.

2. Check the Flapper

Inspect the flapper for any signs of wear or misalignment. If it appears worn, you can try to reposition it or push it down firmly to ensure it seals properly. A proper seal will stop water from leaking from the tank to the bowl.

3. Tighten the Fill Valve

Locate the fill valve, which is usually on the left side of the tank. Sometimes, simply tightening the valve can resolve the issue. A secure fill valve reduces the chances of leaks and can restore normal function.

4. Flush the Toilet

Flushing the toilet can sometimes reset the internal components and may stop the running temporarily. It clears any potential debris that might be causing the issue.

5. Shut Off the Water Supply

If the toilet continues to run and you need to stop it immediately, locate the shut-off valve (usually behind the toilet) and turn it clockwise to close it. This will stop water from flowing into the tank until your handyman arrives.

  • DIY Risks: One wrong move and you could flood your bathroom.

Frequently Asked Questions (FAQs)

Why does my toilet keep running?

A running toilet usually means there’s a problem inside the cistern—most commonly a worn flapper, misaligned float, or faulty fill valve. These issues prevent the tank from sealing properly, causing water to continuously flow into the bowl.

How often should I have my toilet inspected?

It’s a good idea to check your toilet every 6–12 months for worn parts or leaks. Regular inspections can prevent costly water bills and avoid sudden breakdowns that require emergency repairs.

How to fix a running toilet?

You can try adjusting the float, cleaning the fill valve, or replacing the flapper as a temporary fix. However, for a long-lasting solution, it’s best to call a professional like MK Handyman London, who will diagnose and repair the root cause properly.

What should I do if I notice water pooling around my toilet?

Turn off the water supply immediately to prevent further damage. Water pooling could indicate a leaking seal or cracked base, which needs urgent attention from a qualified handyman.
