How Do You Fix a Leaky Toilet?

The fix depends on where the leak is coming from. Here are the most common culprits:

1. The Toilet Flapper

If you’re wondering how do you fix a leaky toilet flapper, the process is straightforward:

  1. Shut off the water supply at the valve behind your toilet.
  1. Flush to drain most of the water from the tank.
  1. Remove the old flapper from the flush valve.
  1. Install a new flapper, making sure it creates a tight seal.
  1. Turn the water back on and test.

This is often the answer to how to stop a leaking toilet, especially when water is slowly running into the bowl.

2. A Leak Into the Bowl (Not the Flapper)

If your toilet is leaking into the bowl but not the flapper, the problem may be:

  • A cracked overflow tube
  • Worn flush valve seat
  • Improper fill valve adjustment

In these cases, replacing the flapper alone won’t solve the issue and that’s when it’s time to call the pros.

3. Other Leak Sources

Not all leaks are inside the tank. Water at the base of the toilet could mean a failed wax ring, loose bolts, or even a cracked toilet. Any of these require immediate attention to prevent floor damage and mold growth.
