Plumbing emergency? Call — don't type
For a burst pipe, a sewage backup or a failed water heater, call 800-754-5076 instead of using the form so we can dispatch right away. While you wait, close the main water shutoff (usually where the water line enters the house, or at the meter) and turn off power or gas to a leaking water heater.
If you smell gas, leave the house first and call SoCalGas or 911 from a safe place outside — don't wait for a plumber. Read more in gas leak safety and how to find your main water shutoff.
Where we work
We're based in Monrovia and dispatch across Pasadena and the San Gabriel Valley:
