Annoying Problem: Toilet That Won’t Stop Flushing Properly

 

Having a toilet that won’t stop flushing can be an incredibly frustrating and inconvenient problem. Not only does it waste a significant amount of water, but it can also cause damage to your plumbing system if left unresolved. Fortunately, fixing a toilet that won’t stop flushing properly is a task that you can tackle yourself with a little knowledge and some basic tools. In this article, we will provide you with step-by-step instructions on how to fix this annoying problem. So, let’s get started!

Step 1: Understanding the Flush Mechanism

 

Before you begin fixing your toilet, it’s important to have a basic understanding of how the flush mechanism works. Inside the toilet tank, you’ll find a fill valve, a flush valve, and a flapper. The fill valve controls the water level in the tank, while the flush valve opens to allow water to flow into the bowl when you flush. The flapper is a rubber seal that covers the flush valve and prevents water from constantly draining into the bowl.

Step 2: Identify the Issue

 

The first step in fixing your toilet is to identify the specific issue causing it to continuously flush. There are several common culprits that you should check for:

 

  • Check the flapper: Lift the toilet tank lid and inspect the flapper. Ensure it is intact and properly covering the flush valve opening. If the flapper is cracked, broken, or doesn’t provide a tight seal, it needs to be replaced.
  • Check the fill valve: The fill valve is responsible for filling the tank with water after a flush. If it’s not functioning properly, the tank won’t stop filling, leading to continuous flushing. Make sure the fill valve is adjusted to the correct water level and is free from any debris or mineral deposits.
  • Check the flush handle and chain: Sometimes, a misaligned or stuck flush handle can cause the toilet to continuously flush. Ensure that the flush handle is properly aligned and the chain connecting it to the flush valve is in good condition.
  • Check the overflow tube: The overflow tube prevents the toilet tank from overflowing. If the water level in the tank is too high, the excess water will continuously drain into the bowl, causing a perpetual flush. Adjust the water level to the recommended height by modifying the float or float arm.

Step 3: Fixing Common Issues

 

Depending on the issue you identified during the previous step, you’ll need to take specific actions to resolve it. Here are the steps to fix some of the common problems:

Replacing the Flapper

 

If the flapper is damaged or fails to seal tightly over the flush valve, follow these steps to replace it:

 

  • Turn off the water supply: Locate the shut-off valve near the base of the toilet and turn it clockwise to stop the water flow.
  • Drain the tank: Flush the toilet and hold down the flush handle to drain as much water as possible from the tank. You can also use a sponge or a towel to soak up any remaining water.
  • Remove the old flapper: Disconnect the flapper chain from the flush handle or the flush valve. Take note of how the flapper is attached before removing it. Unhook or unscrew the flapper from the flush valve.
  • Install the new flapper: Attach the new flapper to the flush valve, ensuring it creates a tight seal. Reattach the flapper chain to the flush handle or flush valve, making sure there is just a little slack.
  • Turn on the water supply: Open the shut-off valve by turning it counterclockwise. Let the tank fill with water and check for any leaks around the flapper. Adjust the chain if necessary.

Adjusting the Fill Valve

 

To adjust the fill valve and resolve issues related to overfilling, follow these steps:

 

  • Turn off the water supply: Similar to the flapper replacement, locate the shut-off valve and turn it clockwise to shut off the water flow.
  • Locate the fill valve: The fill valve is usually on the left side of the toilet tank, connected to the incoming water supply.
  • Adjust the water level: Most fill valves have adjustable float arms or screws to regulate the water level. Follow the manufacturer’s instructions to decrease or increase the water level in the tank to the recommended height.
  • Turn on the water supply: Open the shut-off valve by turning it counterclockwise. Let the tank fill with water and observe if it stops filling at the desired water level.

Fixing the Flush Handle and Chain

 

If the flush handle or chain is causing the continuous flushing, try the following steps:

 

  • Check the flush handle alignment: Ensure that the flush handle is properly aligned and sits correctly on the toilet tank. Adjust, tighten, or reposition the handle if necessary.
  • Adjust the chain length: The chain connecting the flush handle to the flush valve should have a little slack but not be too loose. Make adjustments to the chain length as needed.
  • Test the flush handle: Flush the toilet and see if the handle returns to its original position without sticking or getting stuck. If it doesn’t, consider replacing the flush handle mechanism.

Step 4: Test and Enjoy the Fixed Toilet

 

After completing the necessary repairs, it’s time to test your toilet and ensure it is functioning properly. Here’s what you should do:

 

  • Turn on the water supply: Open the shut-off valve by turning it counterclockwise to allow water to flow into the toilet tank.
  • Let the tank fill: Wait for the tank to refill completely, and listen for any unusual sounds or signs of water leaking.
  • Test the flushing: Give your toilet a few test flushes to ensure that it stops flushing once the water is released from the tank into the bowl. 

Congratulations! You have successfully fixed your toilet that wouldn’t stop flushing properly. By following these step-by-step instructions, you have saved water, prevented potential damage to your plumbing system, and avoided the need for a costly professional plumber. Remember, if you encounter more complex issues or are unsure of any steps, it’s always wise to call a local plumber to ensure the problem is resolved correctly.
