Join Moulton Niguel and the EPA to fix leaks!
Did you know that one leaky toilet can cause your water bill to increase by more than $500?
According to the U.S. Environmental Protection Agency, household leaks can waste more than 1 trillion gallons of water annually nationwide. Common types of leaks found in the home are worn toilet flappers, dripping faucets, irrigation systems, and leaking pipes including a home’s main water service line. While these types of leaks can often be repaired by homeowners, they can go unnoticed and waste thousands of gallons of water per month. This guide will help you identify common plumbing leaks and provide steps to troubleshoot and make repairs yourself.
Throughout the month of March, Moulton Niguel is taking action to help you find and stop leaks around your home. To support Fix-a-Leak Week, we are making it easier than ever to check your toilets for leaks by mailing you a FREE Leaky Toilet Test!

Customers can request a leaky toilet test any time of the year by calling (949) 831-2500 or emailing customerservice@mnwd.com. Need some help on how to perform the dye tab test? Watch the video tutorial below.
