Detect a Water Leak

Tools to help you determine if you have a leak

If you know you have a leak, such as a dripping faucet, it is important to get it fixed promptly. Even a small leak can lead to a dramatic increase in water usage and have a big impact on your water bill. Some common leaks are not so obvious, such as within your toilet tank or irrigation system.

Suspect you might have a hidden leak? The good news is that many leaks are easy to fix – but first you have to find them.

Get to know your water meter – a trusted advisor in detecting leaks

Your water meter is an important conservation tool. It not only measures the water you use, but it can tell you if there is a leak.

Some commercial sites may have a single meter that supplies water for multiple businesses. Private sub-meters can help distinguish how much water individual businesses use and often have low-flow indicators that show when water is passing through the meter.

Learn how to read your meter to carefully monitor changes in your water use. If you need help finding the exact location of your water meter, contact the Engineering Records Department at 415.945.1530.

Track and reduce your water use

For customers in the District’s Automatic Metering Infrastructure (AMI) pilot program, don’t forget you can register with EyeOnWater for online access to monitor water use and setup leak alerts.

Request a billing adjustment for loss of water

If you discover a leak and repair it promptly, you may be eligible to request a billing adjustment for loss of water.

Leaks at your property or in the street

Your water service begins at your water meter. A service line, or pipe, runs from the water main in your street to your property via your water meter. The service line leading to your property is owned and maintained by Marin Water, as is the water meter. The pipe that runs from the meter to your property belongs to you and is your responsibility.
