Before You Call the Plumber, Try These Easy Steps to Fix a Running Toilet

by Anthony Graves

Dealing with a running toilet can be a frustrating and inconvenient problem for many homeowners. Not only does it waste water and increase your utility bills, but the constant sound of running water can be irritating. While calling a plumber may be the first solution that comes to mind, there are simple steps to fix a running toilet by yourself. 

Identify the Cause of the Problem
The first step in fixing a running toilet is to identify the cause of the issue. Common reasons for a running toilet include a faulty flapper, a worn-out fill valve, or a leaky flush valve. To determine the cause, remove the tank lid and inspect the components inside. Look for cracks, leaks, and other signs of damage or wear. Once you have identified the source of the problem, you can proceed with the appropriate fix.

Replace the Flapper

The flapper, a rubber seal located at the tank's base, regulates water flow into the bowl. A worn or damaged flapper results in a continuous leak into the bowl, leading to a constantly running toilet. Replacing the flapper involves detaching it from the flush valve and fitting a new one. This simple repair can halt the running water, thereby mitigating water waste.

Adjust the Fill Valve

The fill valve plays a crucial role in replenishing the tank's water after every flush. A malfunctioning fill valve may cause the toilet to run continuously. To correct this, find the adjustment screw atop the valve and rotate it clockwise. This will lower the water level in the tank, ensuring efficient water flow and eliminating unnecessary running. This straightforward tweak can significantly enhance the toilet's functionality.

Check for Leaks
In some cases, a running toilet may be caused by a leaky flush valve. This component is located at the bottom of the tank and releases water into the bowl when the toilet is flushed. If the flush valve leaks, water constantly flows into the bowl, causing the toilet to run. To detect leaks in the tank, introduce a few drops of food coloring and wait momentarily. A change in the bowl's water color signifies a leak in the flush valve. To fix this issue,  replace the old flush valve with a new one to stop the running water.

Dealing with a running toilet can be a nuisance, but you can easily fix the issue with the right knowledge and tools. By following these easy steps, you can identify the cause of the problem, replace faulty components, adjust the fill valve, check for leaks, and test the toilet to ensure it works properly. Taking the time to address a running toilet promptly can help you save water, reduce your utility bills, and prevent further damage to your plumbing system.
