Why Does My Toilet Keep Running?

February 12, 2024

Stop the Constant Flow

Ever been annoyed by the persistent sound of water running in your bathroom? If the constant trickle from your toilet is driving you up the wall, you’re not alone. In this blog, we’ll explore the common reasons behind the phenomenon and offer some helpful solutions. So, let’s dive into the world of running toilets and discover why they just won’t hush up!

The Culprits of a Constantly Running Toilet

A running toilet can be caused by several factors, each requiring a unique approach for resolution.

Flapper Malfunction

Often, a worn-out or misaligned flapper is the main culprit. The flapper is a rubber piece inside the tank that controls the flow of water to the bowl. If it’s not sealing properly, water will continue to flow, leading to that incessant running sound.

Faulty Fill Valve

Another common issue is a defective fill valve. This component regulates the water level in the tank. When it malfunctions, it can either cause water to continuously fill the tank or not fill it enough, resulting in a never-ending cycle of running water.

Float Ball Problems

The float ball, responsible for shutting off the fill valve when the tank reaches the desired water level, may also be to blame. If it’s damaged or misadjusted, the tank won’t fill properly, and the toilet will keep running.

Troubleshooting and Solutions

  • Check the flapper for wear and tear. If needed, have a professional plumber replace it.
  • Inspect the fill valve for any leaks or malfunctions. A replacement may be necessary.
  • Ensure the float ball is correctly adjusted. If damaged, consider a replacement.

The answer to the question, “Why does my toilet keep running?” often lies in the condition of key components like the flapper, fill valve, and float ball. Identifying and addressing these issues promptly can save water, reduce your utility bills, and bring peace and quiet back to your bathroom.
