Gas Line Repair & Installation in St. Helens, Oregon
Gas line work requires a licensed plumber, proper permits, and pressure testing before gas goes back on. True Flow Plumbing handles gas line repair, new line runs, and appliance connections throughout St. Helens — safely, permitted, and inspected.
Gas Line Service in St. Helens
St. Helens' older homes have gas infrastructure that in some cases dates to when natural gas was first piped into Columbia County — aging black iron pipe with fittings and connectors that are well past their intended service life. Flexible connectors to ranges and dryers in older homes are a particular concern — these connectors have a 10–20 year service life and many in St. Helens' older housing stock have never been replaced. We repair, replace, and upgrade gas lines throughout St. Helens with permits and pressure testing on every job.
🔧 Gas Leak Repair
Smell gas? Leave and call NW Natural first. Once supply is off, we locate the leak, repair or replace the section, pressure-test, and coordinate the inspection.
🍳 New Gas Line Runs
New gas service to a range, dryer, fireplace, or outdoor appliance — we run the line, pull the permit, and schedule the inspection.
🔥 Appliance Connections
Connecting a new gas range, dryer, water heater, or fireplace to an existing supply — flexible connector and shutoff valve installation.
📈 Gas Supply Upgrades
Tankless water heaters and high-BTU ranges need more gas than older supply lines deliver. We upgrade the supply line to meet demand safely.
🏠 Aging Line Replacement
Corroded fittings, outdated flexible connectors, and undersized lines are worth addressing proactively in St. Helens's 1900s–1960s homes.
📋 Pressure Testing
All gas work is pressure-tested before re-pressurizing. Code-required and non-negotiable — we never skip this step.

Frequently Asked Questions
How do I know if I have a gas leak in my St. Helens home?
Natural gas has a rotten-egg smell added so leaks can be detected. If you smell gas, leave the house immediately — don't flip switches or use your phone inside. Call NW Natural's emergency line from outside. Once the supply is shut off, call us to locate and repair the leak.
Do you need a permit for gas line work in St. Helens?
Yes — any gas line work beyond connecting a flexible appliance connector requires a permit in St. Helens and throughout Oregon. We pull the permit, do the work, and schedule the inspection. All gas work is pressure-tested before gas is restored.
Can you add a gas line for a new appliance in St. Helens?
Yes. New gas lines for ranges, dryers, tankless water heaters, fireplaces, or outdoor grills are a common call in St. Helens. We assess your existing gas supply pressure and pipe size to confirm it can support the new load — tankless units in particular often require a supply line upgrade.
