Stop the Flow: A Step-by-Step Guide to Fixing a Running Toilet in Your Bathroom

Table of Contents

A running toilet is a common issue that can cause significant water wastage and lead to increased water bills. Fortunately, a running toilet repair is a relatively simple task that can be accomplished by most homeowners with a few basic tools and some patience. In this blog post, we will provide a step-by-step guide on how to fix a running toilet in your bathroom and restore peace and quiet to your home.

Identify 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 worn-out flapper

      • A damaged fill valve

      • A misaligned float
      • A leaky flush valve

    Turn Off the Water Supply

      Before you begin any repairs, it’s essential to turn off the water supply to your toilet. Locate the water shut-off valve, which is usually situated behind the toilet or on the wall, and turn it clockwise to close it. This will prevent any water from flowing into the toilet while you work.

        Remove the Tank Lid

        Carefully remove the tank lid from your toilet and set it aside in a safe place. This will give you access to the internal components of your toilet, such as the flapper, fill valve, and float.

          Inspect and Replace the Flapper

          The flapper is a rubber component located at the bottom of the tank that creates a seal when the toilet is not in use. Over time, the flapper can wear out or become damaged, causing water to leak from the tank into the bowl. If you suspect a worn-out flapper is causing your running toilet, remove the old flapper by unhooking it from the flush valve and disconnecting the chain from the flush lever. Replace it with a new flapper, ensuring it creates a tight seal with the flush valve.

            Check and Adjust the Fill Valve

            The fill valve is responsible for controlling the water level in your toilet tank. If the fill valve is damaged or not functioning correctly, it can cause the water level to rise too high, resulting in a running toilet. Inspect the fill valve for any visible damage and replace it if necessary. If the fill valve appears to be in good condition, adjust the water level by turning the adjustment screw or moving the float arm to the correct height.

              Inspect and Repair the Flush Valve

              The flush valve is responsible for releasing water from the tank into the bowl when the toilet is flushed. A leaky flush valve can cause your toilet to run continuously. Inspect the flush valve for any signs of wear or damage and replace it if necessary. If the flush valve appears to be in good condition, ensure it is properly seated and aligned with the flapper.

                Test Your Repairs

                Once you have addressed the potential causes of your running toilet, turn the water supply back on and allow the tank to refill. Flush the toilet and check for any leaks or signs of the toilet running. If the problem persists, you may need to consult a professional plumber for further assistance.


                Fixing a running toilet can be a straightforward process that saves you money on your water bill and helps conserve water resources. By following the steps outlined in this guide, you can quickly and easily address the issue and restore your toilet to proper working order.
