How to Fix a Running Toilet With a Button Flush | Saving Water and Sanity


Welcome to Plumbers Sherman TX. In this discussion, we are setting out to explain an important topic: How to Fix a Running Toilet With a Button Flush. It is one of the most common problems in every home.

A running toilet can be an annoying and wasteful problem, causing not only frustration but also an unnecessary increase in water bills. If your toilet features a button flush mechanism and seems to be running continuously, it’s crucial to address the issue promptly.

In this guide, we’ll walk you through the steps to fix a running toilet with a button flush, providing a comprehensive solution to this common household problem.

Understanding the Button Flush Mechanism

Before diving into the troubleshooting steps, let’s briefly understand how the button flush mechanism works. In toilets with a button flush, there are typically two buttons on the top of the tank – one for a partial flush (for liquid waste) and another for a full flush (for solid waste). When you press one of these buttons, it lifts a flush valve, allowing water to flow from the tank into the bowl and flush away the waste. A running toilet occurs when water continues to flow into the bowl after the flush, signaling a malfunction in the flushing mechanism.

Identify the Problem

The first step in fixing a running toilet is to identify the root cause of the issue. Lift the tank lid and observe the flushing mechanism after pressing the buttons. If water is continuously flowing into the overflow tube or if the flush valve doesn’t close properly, you’ve likely found the problem.

Adjust the Water Level

A common reason for a running toilet is an improper water level in the tank. The water level should be about half an inch below the overflow tube. To adjust it, locate the water level adjustment screw or knob on the fill valve. Turn it clockwise to decrease the water level or counterclockwise to increase it. Flush the toilet and observe whether the issue persists.

Inspect the Flapper

The flapper is a rubber seal that covers the flush valve opening at the bottom of the tank. If the flapper is damaged or doesn’t seal properly, water will continuously leak into the bowl. Check the flapper for any signs of wear or deterioration. If you notice any issues, replace the flapper with a new one, ensuring a tight seal.

Clean the Flush Valve

Mineral deposits and debris can accumulate on the flush valve over time, hindering its ability to close properly. To clean the flush valve, turn off the water supply to the toilet and flush to drain the tank. Scrub the flush valve with a brush or a scouring pad to remove any deposits. Turn the water supply back on and check if the problem persists.

Inspect the Chain and Adjust if Necessary

The chain that connects the flush lever to the flapper can sometimes be too loose or too tight. If it’s too loose, the flapper may not lift entirely, causing a weak flush. If it’s too tight, the flapper may not close properly, leading to a continuous flow of water. Adjust the chain length accordingly to ensure smooth operation.

Check for Leaks

A leaking toilet can contribute to a running toilet problem. Add a few drops of food coloring to the tank water and wait for about 15 minutes without flushing. If you see colored water in the bowl, you have a leak. Inspect the tank components, such as the bolts, gaskets, and connections, and replace any damaged parts.

Replace the Fill Valve

If none of the above steps resolve the issue, the fill valve may be faulty. A faulty fill valve can result in an inconsistent water level, leading to a running toilet. Turn off the water supply, flush the toilet to drain the tank, and replace the fill valve following the manufacturer’s instructions.

Will I Need to Replace the Button Flush?

If you’ve followed the troubleshooting steps outlined above and your toilet with a button flush is still running, you might be wondering if the button flush itself needs replacement. In many cases, the issue lies with other components like the flapper, fill valve or chain.

However, if you’ve ruled out these possibilities and the problem persists, it might be time to consider replacing the button flush mechanism. Before doing so, double-check for any visible damage, cracks, or signs of wear on the buttons.

If the buttons appear to be in good condition and the problem persists, consulting a professional plumber may be necessary to determine the best course of action. Remember, regular maintenance and timely repairs can extend the life of your toilet’s flushing mechanism and keep it functioning smoothly.
