Sizing the line
We add up the generator and every gas appliance in the house, measure the run from the meter or tank, and pick the pipe size that keeps the generator fed under full load.

What we do
From the meter to the generator
Running the line
To the generator pad with the right pipe for the job, a shutoff at the unit, a sediment trap and a proper connector.
Test, permit, inspect
Every line is pressure-tested and holds before we call it done. You get a written quote before we start and an itemized invoice with the test and inspection results at the end. We pull the permit, meet the inspector and work with your generator dealer and electrician on timing.
Getting ready for winter too? See our freeze protection tips and all of our gas line services. Backup power for a restaurant or shop? We run commercial gas lines too.
Master-licensed gas work
Getting a generator? Call us before install day.
We'll size the line, handle the permit and have it run, tested and inspected at the pad.
FAQ
Generator gas line questions
Why does a generator need its own gas line sizing?
A standby generator pulls a lot of gas the moment the power goes out, often while your furnace and water heater are running too. If the line is too small, the generator can stall or fail to carry the house right when you need it. We size the line for the generator plus everything else on the system.
Do you install the generator?
We handle the gas side: the line from the meter or tank, the shutoff, sediment trap and connector, the pressure test and the hookup. The generator dealer and a licensed electrician handle the unit, the pad and the transfer switch. We work with them so the gas side is ready for install day.
Natural gas or propane?
Either. In town most homes use natural gas. Around Marble Falls and the Highland Lakes many homes are on propane, and we check the tank size and regulator against the generator's demand. If the tank is too small, we'll tell you what to ask your propane supplier.
Will my gas meter need to be upgraded?
Sometimes. If the meter can't supply the generator and the house at the same time, the gas utility may need to upgrade it. We check during the visit and tell you up front.
Does this need a permit?
Yes, in most of our area. Where a permit is required, we pull it, do the work to code and meet the inspector.
When should I do it?
Before the next storm or freeze, not during it. When a big outage hits, everyone calls at once. Getting the line in ahead of time means the gas side is done, tested and inspected before storm season.

“Just scroll through the reviews and you'll see for yourself that their service is nothing short of pure excellence. A couple of days ago I called for a clog in my dual vanity sink that me and my wife tried to remedy ourselves using various methods (auger, plunger method, etc.) To no avail, we gave up and gave Economy Plumbing Services a call through Groupon because their prices fit our budget. I spoke to Michael, and he showed up at the exact time that was scheduled today. Not only did Michael solve our issue and go above and beyond, but he OVER educated us on the THE CAUSE of the issue, the SOLUTION, and PREVENTATIVE MAINTENANCE to do ourselves to ensure that our plumbing stays in the best running condition possible. We video recorded all the information he provided us for our own educational purposes. He also did a free water heater check for us! This was all a display of showmanship of utmost integrity - and we WILL be signing up for their VIP service. I would highly recommend this company to anyone in the Austin and surrounding areas. Michael, thanks again for everything. 👍”
