Why Does Your Toilet Keep Running? 5 Possible Reasons

A running toilet can be a huge irritation for homeowners and apartment owners alike. Not only does it waste water, but it can also increase your utility bill and lead to other plumbing problems down the line. If you've been dealing with a toilet that won't stop running, it's important to understand the potential causes. Here are five possible reasons why your toilet keeps running and how you can fix the issue.

Faulty Flapper Valve

One of the most common reasons why a toilet keeps running is a faulty flapper valve. This component regulates the flow of water from the tank to the bowl and prevents water from continuously running. If it becomes damaged or worn, it won't create a proper seal, causing water to constantly leak into the bowl. To fix this issue, you'll need to replace the flapper valve with a new one.

Malfunctioning Fill Valve

Another possible culprit for a running toilet is a malfunctioning fill valve. This valve controls the water level in the tank and refills it after a flush. If it's not working correctly, it can lead to an overfilled tank, resulting in water constantly flowing into the overflow tube. In some cases, adjusting the fill valve's float can fix the issue. If not, replacing the fill valve may be necessary.

Broken Overflow Tube

The purpose of the overflow tube is to prevent the tank from overflowing in case the fill valve malfunctions. However, if the tube is cracked or broken, it can cause a continuous flow of water into the bowl. In such situations, replacing the overflow tube is necessary to stop the toilet from running.

Mineral Deposits

Mineral deposits can build up in the fill valve, flapper valve, and other components of your toilet's plumbing system over time. This can cause issues with water flow and lead to a constantly running toilet. To fix this issue, you'll need to clean or replace the affected components.

Loose or Misaligned Chain

If the chain connecting the flapper valve to the toilet handle is loose or misaligned, it can prevent the flapper from properly sealing. This can cause water to continually flow into the bowl, even after a flush. Adjusting the chain or replacing it altogether can usually solve the problem.

A running toilet can be a frustrating and costly problem, but with a little bit of knowledge and effort, it can be fixed. If you're dealing with a constantly running toilet, start by checking the flapper valve, fill valve, overflow tube, and chain. If you're not comfortable doing this yourself, don't hesitate to contact a licensed plumber for assistance. A professional plumber can diagnose the issue and provide a solution that will put an end to your running toilet once and for all.
