Why Does My Toilet Keep Running? Common Causes and Fixes
A running toilet might seem like a minor inconvenience, but over time, it can waste hundreds of gallons of water and drive up your utility bills. If you’ve been asking yourself, “Why does my toilet keep running?” you’re not alone. At Pro Quality Plumbing Inc., we help homeowners across [local area] diagnose and fix common plumbing issues, including persistent toilet problems.
Common Causes of a Running Toilet
Faulty Flapper
The most common reason a toilet keeps running is a worn-out flapper. The flapper is the rubber seal at the bottom of the tank that lifts to release water when you flush and then reseals the tank. If it’s warped, cracked, or misaligned, water can continuously leak into the bowl, causing your toilet to run nonstop.
Float Issues
Your toilet’s float controls the water level in the tank. If the float is set too high or has become stuck, the water may continue filling past the proper level. This can trigger the overflow tube and result in a running toilet.
Fill Valve Problems
A malfunctioning fill valve can also cause continuous water flow. If the valve doesn’t shut off properly once the tank is full, water will keep running. This is a common issue in older toilets or if sediment builds up inside the valve.
Chain or Handle Problems
Sometimes, a running toilet is caused by a simple mechanical issue. If the chain connecting the handle to the flapper is too tight or tangled, it can prevent the flapper from sealing completely. Similarly, a loose or misaligned handle may not allow the flapper to close properly.
