Seismic Gas Shut-Off Valve
Protect your home from the fire risk after an earthquake
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.

Honest pricing
How much does seismic gas shut-off valve cost?
Every job is different, so we don't guess over the phone and then change the number on site. We look at the problem, then give you a written flat-rate price before any work starts. The price you approve is the price you pay — and it's the same at 3 a.m. on a Sunday as it is on a Tuesday afternoon.
What affects the price:

- City permit and inspection requirements
- Whether water heater strapping or other corrections are added
Real customers
What homeowners say after the rescue.
Our reviews come from real emergencies — and how we handled them.
Emergency Sewer Backup
“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.”
Sarah M.
Los Angeles, CA
Slab Leak Detection
“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.
Los Angeles, CA
Water Heater Replacement
“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.”
