A running toilet can be annoying and frustrating. It also wastes water and can lead to dramatic water bill increases. However, fixing a running toilet is relatively easy and you can do it by yourself. You only need general plumbing knowledge and some basic tools.

Here is a guide by our Oro Valley toilet installation and repair experts exploring the common causes of a running toilet and how you can fix the problem.

Common Causes of a Running Toilet

  1. Faulty flapper. The flapper valve controls the flow of water from the tank to the bowl. When the flapper has issues, including improper sealing, it allows water to continuously flow into the bowl leading to a running toilet.
  2. Incorrect water level. Water often spills into the overflow tube when the tank water level is too high causing the toilet to run.
  3. Issues with the fill valve. The fill valve controls the tank water refills after a toilet flush. Problems like the float valve being too high can cause a fill valve to shut improperly. This often causes the tank to overfill leading to a running toilet.
  4. A malfunctioning flush handle. The flush handle starts the flushing and refill process of your toilet. A broken flush handle that gets stuck in the down position can lead to continuous flushing and a running toilet.

Tools and Materials Needed

Some of the basic tools you need to fix a running toilet include:

  • Adjustable wrench.
  • Replacement parts such as a flapper or fill valve

You also need some basic materials, including cleaning supplies and towels or rags.

Step-by-Step Guide to Fixing a Running Toilet

Step 1: Turn Off the Water Supply

This is the first step before beginning your repairs. Locate the shut-off valve and turn off the water supply to the toilet. You can find the shut-off valve behind the toilet. You should also flush the toilet to empty the tank.

Step 2: Inspect and Replace the Flapper

The second step involves opening the toilet tank to check the flapper for wear and tear. If you notice issues with the flapper, including not sealing properly, replace it. Disconnect the old flapper from the chain and hinge to remove it. Attach the new flapper.

Step 3: Adjust the Water Level

Fill the tank and check whether the water level is about an inch from the top of the overflow tube. Adjust the fill valve if the water level is too high. You should also adjust the float valve to the correct water level.

Step 4: Check the Fill Valve

If the toilet is still running even after adjusting the water level, inspect the fill valve for issues. Replace or repair the fill valve as needed. Turn off the water supply and empty the tank. Disconnect the water supply line from the fill valve and remove the valve. Follow the manufacturer’s instructions to install a new fill valve. Reconnect the water supply line after you replace the fill valve.

Step 5: Test the Flush Handle

Test the flush handle to ensure it is moving freely. Tighten or replace the handle if it’s loose or broken. Refill the tank and check if the toilet has stopped running. Flush the toilet a few times to confirm there are no leaks and it is working properly.

When to Call an Oro Valley Toilet Service Professional

If your toilet continues to run even after implementing the above steps, contact a professional plumber like our experts at Curtis Plumbing. You should also contact a professional if the problem keeps coming back even after multiple fixes and repairs.

In most cases, a persistent running toilet is a sign of a larger plumbing problem that is not specific to the toilet. A professional will conduct a comprehensive inspection of your plumbing system to find the root cause and extent of the problem.
