Standby Generator Gas Line Installation in Western Washington
Your standby generator is only as reliable as its fuel supply. We size and install dedicated gas lines to ensure your generator starts and runs at full capacity — every time the power goes out.
Call (425) 343-5566 for a Free EstimateWhy Proper Sizing Matters
A standby generator that’s undersupplied with gas will run poorly or fail entirely — the one time you need it most. We calculate the exact BTU load of your generator and size the gas line correctly from the meter to the unit.
- ✦Proper pipe sizing — calculated for the generator’s BTU demand plus all other appliances on the line
- ✦Dedicated shutoff valve — installed at the generator connection point
- ✦Pressure tested — every line we install is pressure tested before the generator is connected
- ✦Fully permitted — we pull the mechanical permit and pass final inspection

Common Questions
How do I know what size gas line I need?
We calculate this based on your generator’s kW rating (which translates to BTU demand), the distance from your meter, and the total load of all appliances on your gas system. We handle the math — you just tell us the generator model.
Can I use propane instead of natural gas?
Yes. Many standby generators run on LP propane, especially in areas without natural gas service. We install propane supply lines and connect to your generator’s regulator and fuel inlet.
How far can you run the gas line?
There’s no fixed maximum — it depends on pipe diameter and the BTU demand. Longer runs require larger pipe to maintain adequate pressure. We size the pipe correctly regardless of the distance involved.
Do you coordinate with the generator installer?
Yes. We regularly work alongside electricians and generator dealers. We can coordinate timing so the gas line is ready when the generator is in place, and we attend the final inspection together if required.
