Why Your Toilet Won't Stop Running

Is there anything more frustrating than a toilet that won't stop running? It's a nuisance and can lead to increased water bills. If you've found yourself in this situation, you're not alone. Many homeowners have dealt with a toilet that keeps running after a flush.

Common Causes of a Running Toilet

Various issues can cause a running toilet, and identifying the root cause is the first step in resolving the problem. Here are some of the most common reasons why your toilet won't stop running:

1. Faulty Flapper or Flush Ball

A worn-out or improperly seated flapper or flush ball can allow water to leak from the tank into the bowl continuously. This constant flow of water triggers the fill valve to keep refilling the tank.

What to Do: Inspect the flapper or flush ball for wear and tear. If it's damaged or doesn't seal properly, replace it. Ensure that it sits flush over the flush valve.

2. Faulty Fill Valve

If the fill valve fails to shut off after the tank is full, it will continue to let water flow into the tank. This can happen due to mineral buildup or a malfunctioning valve.

What to Do: Check for mineral deposits that may obstruct the fill valve's operation. If that's not the issue, consider replacing the fill valve.

3. Chain Problems

The chain connecting the flush lever to the flapper or flush ball can become tangled or too tight, preventing the flapper from sealing properly.

What to Do: Adjust the chain length to allow the flapper or flush ball to close completely after flushing.

4. Water Level Adjustment

An incorrect water level in the tank can also cause a running toilet. If the water level is too high, it can overflow into the overflow tube.

What to Do: Adjust the water level in the tank by turning the adjustment screw on the fill valve. Ensure it's set to the correct level, usually marked inside the tank.

5. Float Ball or Cup Issue

The float ball or cup regulates the water level in the tank. The tank may continuously fill with water if it's damaged or set at the wrong height.

What to Do: Check the float ball or cup for damage and adjust its position if necessary to control the water level.

What to Do When Your Toilet Won't Stop Running

Now that you've identified some common causes of a running toilet, it's time to take action and put an end to the constant flush cycle. Here's a step-by-step guide to troubleshooting and fixing the issue:

Step 1: Turn off the Water Supply

To prevent further water wastage, locate the water supply valve near the base of the toilet and turn it clockwise to shut off the water flow to the tank.

Step 2: Remove the Tank Lid

Carefully lift the tank lid off and set it aside. Place it on a soft surface to avoid any damage.

Step 3: Check the Flapper or Flush Ball

Inspect the flapper or flush ball for damage or misalignment. It needs to be replaced if it's worn out or not sealing properly.

Step 4: Check the Fill Valve

Examine the fill valve for any obstructions or signs of malfunction. If you find mineral deposits or a faulty valve, consider replacing it.

Step 5: Adjust the Chain

If the chain connecting the flush lever to the flapper or flush ball is tangled or too tight, adjust it to ensure smooth operation.

Step 6: Adjust the Water Level

Inspect the water level inside the tank and adjust it if necessary. Most tanks have a marked water level line to guide you.

Step 7: Check the Float Ball or Cup

Inspect the float ball or cup for damage and adjust its position to control the water level in the tank.

Step 8: Turn the Water Supply Back On

Once you've made the necessary adjustments and replacements, turn the water supply valve counterclockwise to restore the water flow to the tank.

Step 9: Test the Toilet

Flush the toilet and observe if it stops running after the flush. If it continues to run, recheck your adjustments and ensure all components are functioning correctly.

When to Seek Professional Help

In most cases, you can troubleshoot running toilet on your own. However, there are instances when it's best to enlist the help of a professional plumber, especially if:

  • You've tried all the troubleshooting steps and the toilet still won't stop running.

  • You're not comfortable working with plumbing components.

  • You suspect a more complex issue, such as a damaged valve or pipe.

A qualified plumber has the expertise and tools to effectively diagnose and repair any plumbing problem.

We luckily had gravel drainage so he recommended cleaning out our septic tank completely and putting biodegratible in the drainage field. He was here from 4:00-6:30 and explained everything to my husband. In the past when we had our septic tank pumped they did it incorrectly. I feel confident in Steven’s work and we have a 12 month guarantee. It was costly but for what he did worth every penny. Thank you Steven for your expertise job.

I called the office for water leakage on Sunday morning and they schedule me with Technician arrival in 30 mins. Jason reached on time, investigate the problem and able to find the source of leak in few minutes, which was definitely tricky and I believe only an expert eye like Jason can capture it. He walked me over the issue, fixed it and saved my Sunday morning. RooterPLUS is on my speed dial now for any plumbing issues.

It is usually unlikely that you see someone young working hard and have a good attitude along with it. Robert definitely displayed that while he was at work today and I had the pleasure to meet him and tell you about it. Keep up the good work Robert it will pay off!
