Professional Gas Line Services
Gas work requires specialized licensing, training, and equipment. Improper installation can lead to leaks, fires, explosions, and carbon monoxide poisoning. As a licensed California contractor, Walnut Plumbing has the credentials and experience to handle all residential gas line services safely and in compliance with local codes.
Whether you're adding a gas line for a new outdoor kitchen, replacing a corroded supply line, or upgrading your earthquake safety equipment, our technicians follow strict protocols to protect your family and property. All gas work is permitted and inspected to ensure code compliance.
Earthquake Shut-off Valves
Critical protection for California homes
California law requires seismic gas shut-off valves on new construction and during major renovations. These devices automatically shut off gas flow when they detect earthquake motion, preventing post-earthquake fires that historically cause more damage than the shaking itself. Even if not required for your home, we strongly recommend installing one as a safety measure.
How Earthquake Valves Work
Seismic shut-off valves contain a weighted mechanism that activates during ground motion exceeding a certain threshold (typically 5.4+ magnitude). When triggered, the valve closes automatically, stopping gas flow to your entire home. After an earthquake, a licensed plumber must inspect and reset the valve before gas service can be restored.
Benefits of Installation
- Automatic protection—no action required during an earthquake
- Prevents post-earthquake fires from broken gas lines
- May qualify for homeowner's insurance discounts
- Required by California law for new construction
- Peace of mind for families in earthquake-prone areas
BBQ & Outdoor Kitchen Gas Lines
Permanent gas hookups for outdoor living
Tired of refilling propane tanks? A permanent natural gas line to your outdoor grill provides unlimited fuel, consistent heat, and lower long-term costs. We install gas lines to built-in grills, outdoor kitchens, fire pits, patio heaters, and pool heaters—bringing the convenience of natural gas to your backyard.
Our BBQ Gas Line Process
Site Evaluation
We assess your gas meter capacity, determine the best route for the new line, and calculate BTU requirements for your appliances.
Permit & Planning
We pull required permits from the City of Walnut and plan the installation to minimize disruption to your landscaping.
Installation
Rigid black iron or flexible CSST piping is installed to code, with proper support and protection from damage.
Testing & Inspection
Lines are pressure-tested for leaks, and the city inspector verifies code compliance before final connection.
Appliance Connection
We connect your grill or appliances, verify proper flame characteristics, and ensure safe operation.
Outdoor Appliances We Connect
Gas Appliance Hookups
Safe installation for indoor gas appliances
New appliances need proper gas connections to operate safely and efficiently. Whether you're replacing a water heater, installing a gas dryer, or upgrading to a gas range, our technicians ensure correct sizing, flexible connector installation, and proper venting for combustion appliances.
Appliance Hookup Services
- Water heater connections (tank and tankless)
- Gas range and cooktop hookups
- Gas dryer connections
- Furnace and HVAC gas supply
- Gas fireplace installations
- Generator fuel connections
- Gas line extensions for kitchen remodels
Important: All gas appliances should be installed with approved flexible connectors (not rigid pipe) to allow for movement and reduce earthquake damage risk. We use only connectors listed by the American Gas Association (AGA).
Gas Line Repairs
Older homes may have corroded, undersized, or improperly installed gas lines that need attention. We can repair or replace:
- Corroded black iron pipe connections
- Leaking threaded joints and fittings
- Damaged or kinked flexible connectors
