Repairing a Running Toilet
A running toilet can waste a significant amount of water and increase your utility bills. Understanding the common causes and following a simple repair process can save you money and prevent further issues.Common Causes of a Running Toilet
- Faulty Flapper Valve: The rubber flapper may not seal properly, allowing water to continuously flow from the tank to the bowl.
- Improper Chain Length: The chain connecting the flush handle to the flapper may be too short or too long, preventing the flapper from closing correctly.
- Broken Fill Valve: The fill valve, which controls the water refill process, may malfunction and cause overfilling.
- Worn Out Float: A damaged or incorrectly positioned float can lead to overflows or constant running.
Steps to Repair a Running Toilet
1. Turn Off the Water Supply
Start by shutting off the water supply to the toilet to prevent water flow while you work.- Locate the Shut-off Valve: Usually found near the base of the toilet, turn it clockwise to stop the water.
- Flush the Toilet: Flush to drain most of the water from the tank.
2. Inspect the Flapper Valve
The flapper valve is one of the most common causes of a running toilet.- Check for Damage: Look for cracks, mineral deposits, or wear on the flapper.
- Replace if Necessary: Remove the old flapper and install a new one. Most replacements are affordable and easy to find at hardware stores.
3. Adjust the Chain Length
Ensure the chain connecting the handle to the flapper is not too loose or tight.- Correct the Length: Adjust the chain so it allows the flapper to seal completely without sagging.
- Test the Handle: Pull the handle to ensure smooth operation and a proper seal.
4. Check the Fill Valve and Float
A malfunctioning fill valve or float can also cause constant running.- Inspect the Fill Valve: Ensure it is functioning correctly. Replace it if it’s damaged or outdated.
- Adjust the Float: Raise or lower the float to set the correct water level. This can usually be done by turning a screw or sliding the float along its rod.
5. Test the Toilet
Turn the water supply back on and test the toilet to ensure the issue is resolved.- Observe for Leaks: Watch for water leakage or continuous running.
- Adjust as Needed: If the problem persists, revisit each step to identify and fix the issue.
