Gas line installation
A new gas line is sized, run, tested and inspected before an appliance is ever connected. Here is what that involves in a Seattle home, from the meter to the shut-off valve.
What a gas line install includes
Step by step
- Load calculationEvery appliance on the system, now and planned, decides the pipe size from the meter.
- Meter checkIf the meter cannot deliver the new load, we arrange the upgrade with Puget Sound Energy before install day.
- RoutingThe shortest safe route, through basements, crawl spaces or garages, supported and protected where it passes through framing.
- MaterialsBlack iron pipe, or approved CSST where it suits the run, bonded as required.
- Test and inspectionPressure test held, permit inspected, then gas on and the appliance fired and checked.
Typical Seattle jobs
A line from the meter to a new tankless water heater in the garage. A branch to a kitchen island range during a remodel in Wallingford. A gas fireplace insert in a Magnolia rambler. A dryer line in a Ballard townhouse. In older homes with original galvanized and cast iron, the gas run is sometimes the easiest part.

Installation questions
How much gas pressure does a house have?
Residential gas in Seattle is delivered at low pressure after the meter regulator. Line size, not pressure, is what we design for.
Can a gas line run outside?
Yes, with the right material and protection. Outdoor appliance runs are confirmed during the estimate.
