Push Button Toilet Woes: Uncover the Hidden Cause Behind Its Endless Flow

A continuously running toilet can be both annoying and costly, wasting gallons of water and increasing your utility bills. If you’re facing this issue with your push button toilet, it’s crucial to identify the underlying cause and resolve it promptly. This comprehensive blog post will delve into the various reasons why your push button toilet may be running and provide step-by-step instructions to help you fix the problem.

Common Causes of a Running Push Button Toilet

1. Faulty Flapper Valve

The flapper valve is a rubber seal that sits at the bottom of the toilet tank. When you press the flush button, the flapper valve lifts to allow water to flow into the bowl. However, if the flapper valve is damaged, worn, or misaligned, it may not seal properly, causing a constant flow of water.

2. Worn-Out Fill Valve

The fill valve controls the water level in the toilet tank. When the water level drops, the fill valve opens to refill the tank. If the fill valve is malfunctioning or worn out, it may not close completely, allowing water to continuously flow into the tank and overflow into the bowl.

3. Misaligned Flush Valve

The flush valve is the mechanism that releases water from the tank into the bowl when you press the flush button. If the flush valve is misaligned, it may not close properly, allowing water to leak from the tank into the bowl.

4. Clogged Overflow Tube

The overflow tube is a small tube located at the top of the toilet tank. It prevents water from overflowing the tank if the fill valve fails. If the overflow tube is clogged, water may overflow into the bowl, causing a continuous running toilet.

5. Broken Lift Chain

The lift chain connects the flush button to the flapper valve. When you press the flush button, the lift chain pulls the flapper valve up to release water. If the lift chain is broken or detached, the flapper valve may not open properly, resulting in a running toilet.

6. Worn-Out Toilet Seat

The toilet seat can also contribute to a running toilet. If the toilet seat is loose or wobbly, it can put pressure on the flush valve, causing it to leak.

7. Other Causes

In rare cases, a running push button toilet may be caused by other factors, such as a cracked toilet tank, a faulty flush handle, or a problem with the water supply line.

Troubleshooting and Repair Guide

1. Inspect the Flapper Valve

• Remove the lid from the toilet tank.
• Check the flapper valve for damage, wear, or misalignment.
• If the flapper valve is damaged, replace it with a new one.
• If the flapper valve is misaligned, adjust its position so that it seals properly against the flush valve seat.

2. Test the Fill Valve

• Turn off the water supply to the toilet.
• Flush the toilet to drain the tank.
• Check if the fill valve shuts off completely.
• If the fill valve continues to run, replace it with a new one.

3. Realign the Flush Valve

• Remove the flush valve cap.
• Adjust the flush valve by turning the adjustment screws.
• Tighten the screws until the flush valve closes properly.

4. Clean the Overflow Tube

• Remove the lid from the toilet tank.
• Locate the overflow tube at the top of the tank.
• Use a wire or pipe cleaner to clear any clogs from the tube.

5. Replace the Lift Chain

• Remove the lid from the toilet tank.
• Locate the lift chain and check for any breaks or detachments.
• If the lift chain is broken, replace it with a new one.

6. Tighten the Toilet Seat

• Tighten the bolts that secure the toilet seat to the toilet bowl.
• If the toilet seat is still loose or wobbly, replace it with a new one.

7. Call a Plumber

If you’ve tried the above troubleshooting steps and your push button toilet is still running, it’s recommended to contact a licensed plumber. They can diagnose the underlying issue and perform the necessary repairs to stop the toilet from running.
