WAUKESHA — The Waukesha Water Utility is encouraging customers to check for leaks during this year’s national Fix a Leak Week.

“Leaks can cost families a lot of money,” said the utility’s customer service coordinator, Mary Adelmeyer, in a press release. “Toilet leaks tend to be invisible and are one of the most common leaks.”

The utility is focusing on toilets because they are the main source of water use in the home, accounting for nearly 30 percent of an average home’s indoor water consumption.

When toilets leak, hundreds of gallons of water a day can be wasted without the homeowner’s knowledge, the press release states.

Toilet leaks are common, so the utility recommends checking for leaks at least twice each year.

Replacing toilets that were installed in 1993 or earlier with a more water efficient model is one of the best ways to help reduce water usage. If you live in the city of Waukesha, you may also qualify for the $100 toilet rebate and a $25 shower head rebate.
