A toilet that won’t stop running is more than just an annoyance—it can waste hundreds of gallons of water each day and significantly increase your utility bill. Fortunately, this is a common plumbing issue, and in many cases, the cause is easy to identify. Here’s what you should know and what to do if your toilet keeps running.

Common Reasons a Toilet Keeps Running
The most frequent cause of a running toilet is a problem inside the tank. When you remove the tank lid, you’ll usually find one of these issues:
A faulty flapper: The rubber flapper at the bottom of the tank creates a seal that holds water until you flush. Over time, flappers can warp, crack, or become misaligned, allowing water to leak continuously into the bowl.
A damaged fill valve: The fill valve controls how much water refills the tank after flushing. If it’s worn or malfunctioning, it may never fully shut off, causing constant water flow.
Improper float height: The float signals the fill valve to stop filling the tank. If it’s set too high, water will continue to run into the overflow tube.
Loose or tangled chain: If the chain connecting the flush handle to the flapper is too short or tangled, the flapper may stay partially open.
Quick Fixes You Can Try
Before calling a plumber, there are a few simple steps you can take:
-
Jiggle the flush handle to see if the flapper reseats properly
-
Adjust the float to lower the water level in the tank
-
Check the flapper for visible wear or mineral buildup
-
Ensure the chain has a little slack and isn’t catching
These quick adjustments can often stop the problem immediately.
When to Call a Professional Plumber
If your toilet continues to run after basic troubleshooting, it’s time to call a professional. Persistent running can indicate deeper issues, such as a failing fill valve or internal components that need replacement. A licensed plumber can quickly diagnose the problem, replace worn parts, and ensure your toilet is operating efficiently.
Why You Shouldn’t Ignore a Running Toilet
A constantly running toilet can waste up to 200 gallons of water per day. Beyond higher water bills, the excess moisture can contribute to wear on plumbing components and increase the risk of leaks over time.
