A constantly running toilet can waste hundreds of gallons of water per day, increasing your water bill and potentially leading to costly repairs. Fortunately, most running toilet issues are easy to fix.
In this guide, we’ll cover the most common reasons your toilet won’t stop running and how to fix them.
Common Causes of a Running Toilet
1. Faulty Flapper
The flapper controls water flow from the tank to the bowl. If it’s worn out, water will continuously leak into the bowl.
Solution:
Turn off the water supply.
Remove the old flapper and install a new one.
2. Overflow Tube Issues
If water is constantly draining into the overflow tube, your toilet is wasting water.
Solution:
Adjust the float arm to lower the water level.
3. Broken Fill Valve
A faulty fill valve can prevent the tank from refilling properly.
Solution:
Replace the fill valve by following manufacturer instructions.
When to Call a Plumber
If your toilet continues to run despite DIY fixes, it might be a sign of deeper plumbing issues. A professional plumber in Lexington, KY can quickly diagnose and repair the problem.
