What Is Gas Line Rerouting & Upsizing?
Gas line rerouting and upsizing is the modification of existing gas supply to serve new or relocated appliances. When remodels add BTU demand, we recalculate, reroute pipes, and upsize the supply line as needed. In Las Vegas, kitchen and outdoor living remodels often require this.
About Gas Line Rerouting & Upsizing in Las Vegas Valley
When Las Vegas homeowners in Green Valley, Sovana, or along State Streets undertake kitchen expansions or outdoor living upgrades, gas line rerouting becomes a technical necessity-not an afterthought. Nevada's caliche-heavy soil complicates trenching for underground runs, while Clark County building codes require licensed contractors to pull permits and submit load calculations before any gas line modification. Active Plumbing recalculates total BTU demand for every project, accounting for added appliances like 48-inch commercial-style ranges, tankless water heaters, or outdoor fire features.
We size pipe to IFGC and NFPA 54 standards, using Schedule 40 black iron or CSST (Gastite or TracPipe) where flexibility is needed. After installation, we conduct thorough pressure testing per NV Energy requirements before requesting final inspection. Customers across Henderson and North Las Vegas frequently combine this work with our Gas Leak Detection & Repair service when aging supply lines show wear.
Our broader Gas Line Services handle everything from meter sets to appliance connections. If your remodel also affects drains, our Drain Cleaning specialists are available. Call Active Plumbing at (702) 438-3357 to schedule your gas line rerouting assessment today.

Gas Line Rerouting & Upsizing - Frequently Asked Questions
Gas line rerouting in Las Vegas typically runs $500-$2,500 depending on pipe length, access difficulty, and permit fees. Upsizing to larger diameter lines for added appliances costs more. Active Plumbing provides upfront quotes before any work begins, with no surprise charges.
Active Plumbing usually schedules gas line rerouting within 1-3 business days in Las Vegas. For urgent situations, our Gas Line Services team handles priority calls across the valley, including Henderson and North Las Vegas, minimizing disruption to your household's gas supply.
We primarily use CSST and black iron pipe, both approved under Nevada codes. Older Las Vegas homes often have undersized half-inch lines that can't support added appliances. Upsizing to three-quarter-inch or one-inch lines resolves pressure drops and safely supports ranges, dryers, and outdoor grills. If we're already working in your walls, we may also recommend Whole-House Repipe to address aging water lines simultaneously.
Active Plumbing is licensed, bonded, and fully permitted for gas work throughout Las Vegas and Sunrise Manor. Our plumbers handle everything from Tank Water Heater Installation to full gas line upsizing under one roof, saving you the hassle of coordinating multiple contractors for related projects.
