Gas Line Repair & Installation in Portland, Oregon
Gas line work requires a licensed plumber, proper permits, and pressure testing before the gas goes back on. True Flow Plumbing handles gas line repair, new line runs, and appliance connections throughout Portland — safely, permitted, and inspected.
Gas Line Service in Portland
Portland's older homes were built during the era when gas was the primary heating and cooking fuel — which means extensive gas line infrastructure that has been in the ground since the 1920s and 1930s. We handle gas line repairs for aging connections, new gas line runs for appliance additions (gas ranges, gas dryers, gas fireplaces), and the gas line upgrades required for whole-home tankless water heater installations. We're licensed to do gas work in Portland and pull all required permits.
🔧 Gas Leak Repair
If you smell gas, leave the house and call NW Natural first. Once the supply is shut off, we locate the source of the leak, repair or replace the affected section, pressure-test the system, and coordinate the gas-on inspection.
🍳 New Gas Line Runs
Adding gas service to a kitchen range, dryer, fireplace, or outdoor appliance where there's no existing line — we run the line, pull the permit, and schedule the inspection.
🔥 Appliance Connections
Connecting a new gas range, dryer, water heater, or fireplace insert to an existing gas supply — flexible connector installation and shutoff valve placement.
📈 Gas Supply Upgrades
Tankless water heaters and high-BTU ranges often require larger gas supply lines than what existing infrastructure can deliver. We upgrade the supply line to meet the demand safely.
🏠 Aging Line Replacement
Older Portland homes have gas lines that have been in the ground for decades — corroded fittings, outdated flexible connectors, and undersized supply lines are all worth addressing proactively.
📋 Pressure Testing
All gas line work is pressure-tested before the system is re-pressurized with gas — this is non-negotiable and required by code. We never skip this step.

Frequently Asked Questions
How do I know if I have a gas leak in my Portland home?
Natural gas has a sulfur (rotten egg) smell added specifically so leaks can be detected. If you smell gas, leave the house immediately — don't flip any switches or use your phone inside. Once outside, call your gas utility (NW Natural) to shut off the supply, then call us to locate and repair the leak. Never try to find or fix a gas leak yourself.
Do you need a permit for gas line work in Portland?
Yes — any gas line work beyond connecting a flexible appliance connector requires a permit in Portland and throughout Oregon. We pull the permit, do the work, and schedule the inspection. The permit process protects you — it ensures the work is pressure-tested and inspected by the city before gas is turned back on.
Can you add a gas line for a new appliance in Portland?
Yes. Running a new gas line for a range, dryer, tankless water heater, fireplace, generator, or outdoor grill is a common job we do in Portland. We assess your existing gas supply pressure and pipe size to confirm it can support the new load — some appliances, particularly whole-home tankless water heaters, require a supply line upgrade to meet the BTU demand.
