How Much Does a Constantly Running Toilet Cost?

A toilet that runs and runs stresses your bank account as well as your nerves. The good news is that the cause of a running toilet is usually a broken floater or flapper that can be easily and inexpensively fixed. If it’s something else, it may mean that you’ll need to call a plumber or replace the toilet altogether.

A running toilet that’s not fixed can waste a gallon of water in half a minute. This adds up to thousands of gallons of water every month, even if the leak is considered moderate. This can increase your yearly water bill by $1,000 to $2,500.

You may be surprised to learn that a whirlpool doesn’t have to be swirling around in your toilet bowl for your toilet to be running. The problem can be nearly silent and still, and you won’t notice until you get your water bill. One trick to see if your toilet is leaking is to add a few drops of food coloring in the toilet tank, and then let it sit for about half an hour. If you find the color in your toilet bowl, you have a leak. If the leak isn’t caused by a floater or a flapper, you’ll need to call in a plumber to find the source of the problem.

Another way to know if your toilet is running is to look for condensation around the toilet’s base. An additional red flag is a stain on the floor near the toilet. A stain is a sign that the leak has been going on for a while.

Here are some other causes of a costly toilet leak besides a broken flapper.

The Toilet Handle Is Old

Some toilet handles are so old that they’ve corroded into the down position even after you’ve flushed the toilet. This causes the flapper to stay open and the toilet to run and run. Fortunately, this problem can be solved by installing a new handle.

The Water Supply Line Leaks

Water supply lines can leak for various reasons, but like floats and toilet handles, they’re easy to fix unless the pipe is cracked. In that case, a plumber will need to replace it.

The Wax Ring Around the Base of the Toilet Is Damaged

Like everything else, the wax ring at the base of the toilet can grow old and crack. When this happens, the wax ring can no longer stop water from the toilet from leaking out, nor can it keep out sewer smells. If the wax ring is damaged, turn off the water supply, and then contact a plumber.
