You can use your water meter to check for a leak by reading it, making sure no water is used for a couple of hours, and then reading it again. If the meter moved while nothing was running, water may be leaking somewhere in the system.
This simple test does not show where a leak is. It can help you decide whether a hidden leak is worth looking into before stains, bills or damage give you a clearer sign.
How the Meter Test Works
The U.S. EPA suggests checking the meter before and after a two-hour period when no water is used. The basic steps are:
- Make sure every faucet, toilet, washer, dishwasher and other fixture is off and not running.
- Write down the numbers on the meter or take a clear photo.
- Wait about two hours without using any water.
- Read the meter again and compare.
Some meters also have a small dial or symbol that turns when water flows, even in tiny amounts. If it moves while everything is off, that may be another hint of a leak. Meter styles differ, so the parts may look different on yours.
Using Your NYC Water Account
In New York City, many water meters send readings automatically. The NYC DEP billing FAQ explains that customers can track water use online through My DEP Account and sign up for leak alerts. Looking at your use over time can show if it jumped without a clear reason.
A higher reading is a clue, not proof. More people in the home, guests or a new appliance can also raise water use.
When the Test Is Hard to Use
Not everyone can reach a meter. In many apartment buildings, one meter serves the whole building, so a reading cannot point to a single unit. Renters and condo owners may need to ask the super or property manager for help.
In a house, the meter is often found where the water line enters, such as a basement or utility area. Only check it if you can reach it safely. Do not open meter covers or move equipment that belongs to the water service.
If the Meter Says Something Is Leaking
A moving meter means water is going somewhere, but finding the source is a separate job. It could be a running toilet, a dripping fixture, a hidden pipe or a line outside the building. Looking for obvious signs first, like running water sounds or damp spots, may help.
If the source is still not clear, that is where professional leak detection can help narrow it down. The method depends on the property and where the leak may be.
