A toilet that keeps running can be annoying, but the sound isn’t the only problem. A running toilet can waste water and raise your monthly water bill. It can also be a sign that a part inside the toilet tank is worn out or isn’t working correctly.
Some toilet problems are simple to fix, while others may need professional toilet repair. Knowing what causes a toilet to keep running can help you decide what to check and when it’s time to call a plumber.
Common Reasons Your Toilet Keeps Running
After you flush, the toilet tank should fill to the right level and stop. If water continues to flow, a part inside the tank may need to be adjusted or replaced.
The Flapper Is Worn Out
The flapper is a rubber part at the bottom of the toilet tank. It lifts when you flush, allowing water to enter the bowl. It should then close and create a tight seal.
Over time, the flapper can wear out, crack, or collect mineral buildup. If it doesn’t seal properly, water will continue leaking into the bowl, causing the toilet to keep running.
Replacing the flapper may solve the problem. If the toilet continues running, another part may be causing the issue.
The Toilet Chain Is Too Short or Too Long
A chain connects the toilet handle to the flapper. If it’s too short, it may keep the flapper from closing. If it’s too long, it can become trapped under the flapper.
The chain should have a small amount of slack when the toilet isn’t being flushed. Adjusting it may be enough to stop a running toilet.
The Fill Valve Isn’t Working Properly
The fill valve controls the water entering the toilet tank. Once the tank reaches the correct water level, the valve should shut off.
A worn fill valve may continue allowing water into the tank. You may hear constant running or hissing sounds. The valve may need to be adjusted or replaced to stop the problem.
The Float Is Set Too High
The float tells the fill valve when to stop adding water. If it’s set too high, water may continue filling the tank and flow into the overflow tube.
Remove the tank lid and check the water level. If water is constantly entering the overflow tube, adjusting the float may solve the problem.
If the float won’t stay in the right position, a plumber can inspect the toilet and find the cause.
How Much Water Can a Running Toilet Waste?
A running toilet can waste a large amount of water over time. Since the water usually flows directly into the bowl, the problem can be easy to miss.
You may notice a higher water bill, hear the toilet filling when no one has used it, or see movement in the toilet bowl.
If your toilet keeps running after you’ve checked the parts inside the tank, professional toilet services can help find the problem and stop unnecessary water waste.
Can I Fix a Running Toilet Myself?
Some problems can be handled with simple adjustments. You can check the flapper, chain, float, and water level inside the tank.
However, replacing parts without knowing what’s causing the problem can lead to more frustration. Damaged seals and other worn parts may also cause a running toilet.
If you’ve made basic adjustments and the toilet continues running, professional plumbing repair can find the cause and help prevent more water waste.
When Should You Call a Plumber for a Running Toilet?
Call a plumber if the toilet continues running after simple adjustments or if the problem keeps coming back.
You should also schedule toilet repair if you notice water around the toilet, weak flushing, frequent clogs, unusual sounds, or cracks in the tank or bowl.
A plumber can inspect the toilet, find the problem, and explain your repair options before work begins.
