Why Does My Toilet Keep Running?

A constantly running toilet is a common plumbing issue that can waste a lot of water and increase your utility bill. Here are some possible reasons why it happens and how you might fix it.

Common Causes

• Faulty Flapper – The rubber flapper inside the tank may not be sealing properly, allowing water to keep flowing into the bowl.

• Chain Issues – If the chain connected to the flapper is too long or too short, it can prevent the flapper from sealing correctly.

• Float Problems – A misadjusted float can cause the tank to overfill, leading to continuous running water.

• Worn-Out Fill Valve – If the fill valve is faulty, it might not shut off properly, keeping water flowing.

How to Fix It

• Check & Replace the Flapper – Turn off the water supply, open the tank, and inspect the flapper. If it looks worn or doesn’t sit properly, replace it.

• Adjust the Chain – Make sure the chain has a little slack but isn’t too loose. Adjust or replace if necessary.

• Adjust the Float – If water keeps running, lower the float by adjusting the float arm or turning the screw on a newer valve.

• Replace the Fill Valve – If none of the above fixes work, the fill valve may be defective and needs replacement.

When to Call a Professional

If you've tried these steps and your toilet is still running, it could be a more serious issue, such as a problem with the water pressure or internal plumbing components. A plumber can diagnose and fix the problem properly.
