After a major earthquake, broken gas lines and appliance connections are a leading cause of fires. A seismic gas shut-off valve sits on your gas line just downstream of the utility meter and automatically closes when it senses strong shaking, stopping the flow of gas into the house.
Several Los Angeles-area jurisdictions require a seismic gas shut-off valve or excess flow valve for new construction, certain remodels and additions, or at the time of sale. Requirements and approved valve types vary by city, so we confirm what applies to your property before installing.
We install approved valves to manufacturer and code requirements, pull permits where they're required, and give you the documentation you need for escrow or final inspection. While we're there, we can check your water heater's seismic strapping — also required in California at point of sale.

Our reviews come from real emergencies — and how we handled them.
“We had a sewer backup on a Sunday night — our laundry room was completely flooded. I called Rooter Rescue at 9 PM and they had a tech at the door within 45 minutes. He cleared a major root intrusion in the main line and had everything flowing again by midnight. I couldn't believe the response time. They're the only plumber I'll ever call.”

“My water bill had been climbing for months and I couldn't figure out why. Rooter Rescue used electronic detection equipment to find a slab leak under my kitchen floor without ripping up a single tile — found it in under an hour. The repair was clean, fast, and came in exactly at the estimate. These guys are total pros.”
Mike T.

“My water heater died on a Friday morning. I called three plumbers — two couldn't get to me until next week. Rooter Rescue had a new unit installed that same afternoon. The tech explained every option clearly, gave me a fair price without any pressure, and left the work area cleaner than he found it. Five stars isn't enough.”
