If a customer suspects a leak at their property, the Division recommends doing a “time test.” In order to do this, locate the meter and write down all the numbers as they appear on the meter’s register. Do not use any water for 4-5 hours. At the end of this time, go back to the meter and see if the numbers have changed. If so, there may be a leak at the property. The customer may then want to contact a licensed plumber or a leak detection company.
