Detecting Water Leaks

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 household 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. Check out summary guidance on this page and download our leak detective brochure to learn more.

Leaks in your home 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 home 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 home belongs to you and is your responsibility.
