In Encinitas, finding a hidden leak means confirming it at the meter, then working through the supply piping, fixtures and irrigation until the source is pinned down. Water may come from San Dieguito Water District or Olivenhain Municipal Water District depending on your neighborhood. Call the number on this page to be connected with a local plumber in Encinitas.

Encinitas homes and leaks
The median Encinitas home was built in 1980, and about 75% of housing units are single-family houses, many of them on slabs. Supply piping of that age can thin at joints and rub points, and coastal salt air corrodes outdoor valves and hose bibs. The water provider depends on the area: San Dieguito Water District covers Cardiff, Old Encinitas, Leucadia and part of New Encinitas, while Olivenhain Municipal Water District serves other parts of the city. The City's MyEncinitas Map shows which utilities serve an address.
What to do now
- Turn off every faucet, appliance and the irrigation controller.
- Read the meter, wait 30 minutes without using water and read it again.
- If the reading changed, close the main shutoff and check again. If it stops moving, the leak is inside the house; if it keeps moving, look between the meter and the house.
- Check under sinks, behind toilets and around the water heater for damp spots or corrosion.
- For water surfacing near the meter or street on San Dieguito Water District service, call its after-hours emergency line at (760) 633-2922 or customer service at (760) 633-2658. Olivenhain customers should use the number on their bill.
- Write down what you found, including meter readings and times, so the plumber can start in the right place.
