How to Tell if Toilet is Running

If you have ever heard a constant hissing or trickling sound coming from your bathroom, you may have a running toilet. This not only wastes water and money, but it can also be annoying to listen to. In this guide, we will discuss how to tell if toilet is running and what steps you can take to fix it.

How to Tell if Toilet is Running

Necessary Items

Before you can determine if your toilet is running, there are a few items that you will need. These include:

  • A clean towel or paper towels
  • Food coloring or dye tablets (optional)
  • Screwdriver
  • Adjustable wrench (optional)

Having these items on hand will make it easier to diagnose and fix the issue with your toilet.

12 Steps on How to Tell if Toilet is Running

Step 1: Remove the Tank Lid

The first step is to remove the lid of your toilet tank. This will give you access to all the components inside and allow you to inspect them. And be sure to place the lid on a flat surface nearby so it doesn’t get damaged.

Step 2: Check the Flapper

The flapper is a small rubber piece located at the bottom of the tank. It controls the flow of water from the tank to the bowl when you flush. If it is not sealing properly, water will continuously leak into the bowl, causing the toilet to run.

Step 3: Check the Chain

The chain connects the flapper to the flush handle. If it is too long, it can get caught under the flapper and prevent it from closing properly. Make sure there is enough slack in the chain for the flapper to close completely.

Step 4: Listen for Hissing or Trickling Sounds

If you don’t notice any obvious issues with the flapper or chain, listen closely for any hissing or trickling sounds from the tank. This is a clear indicator that water is still flowing into the tank even when it’s not being flushed.

Step 5: Add Food Coloring to Tank (Optional)

If you’re having trouble detecting a leak, you can add a few drops of food coloring or dye tablets to the tank. Wait 10 minutes, and then check the bowl for any discoloration. If there is, it means the flapper is not sealing properly.

Step 6: Check the Fill Valve

The fill valve is located on the left side of the tank and controls how much water enters the tank after a flush. If it is not adjusted properly, it can lead to excess water flowing into the tank and causing it to run.

Step 7: Adjust the Fill Valve

To adjust the fill valve, turn the screw on top of it in a clockwise direction to decrease the amount of water entering the tank. You may need to experiment with different settings until you find the right one.

Step 8: Check for a Broken Float

The float is a small plastic or metal ball that sits on top of the water in the tank. If it is broken, it will not rise with the water level and signal the fill valve to shut off. This can cause the tank to continuously fill and run.

Step 9: Replace the Float

If you notice that the float is broken or damaged, it will need to be replaced. You can find a replacement at your local hardware store. Even if it is not visibly damaged, it may still be causing issues and should be replaced.

Step 10: Check for a Cracked Fill Valve

Inspect the fill valve for any cracks or damage. If you notice any, it will need to be replaced. A cracked fill valve can lead to water constantly leaking into the tank and causing it to run. And be sure to turn off the water supply before replacing it.

Step 11: Check for a Cracked Flapper

Inspect the flapper for any cracks or warping that may prevent it from sealing properly. If you notice any damage, it will need to be replaced. And again, remember to shut off the water supply before making any replacements.

Step 12: Replace Any Damaged Parts

After inspecting all the components, replace any damaged or worn parts as needed. Once you have fixed the issue, turn the water supply back on and test your toilet to see if it is still running. But don’t forget to clean up any excess water and put the lid back on the tank before using it again.

Turn the Water Supply Back on

A running toilet can be a frustrating and costly problem. However, with these 12 steps, you can easily determine if your toilet is running and make the necessary repairs. Remember to regularly check and maintain your toilet to prevent future issues and save water.

If you encounter any difficulties or are unsure about how to fix the problem, don’t hesitate to call a professional plumber for assistance. By taking these steps, you can keep your toilet running smoothly and efficiently.  So next time you hear that hissing or trickling sound, you’ll know exactly what to do!
