Endless Fuel Supply

Expert Gas Line for Generator Installation in McKinney, TX

The biggest weakness of a portable generator is running out of fuel. Top Flow Plumbing Co. solves this problem permanently. We provide professional gas-line-for-generator installation, connecting your unit directly to your home's natural gas or propane supply for unlimited run time.

The Hassle of Gasoline Generators

Constant Refueling

A standard portable generator empties its tank every 6-8 hours. That means waking up at 3 AM in a storm just to keep the lights on.

Storage Safety

Storing gallons of gasoline in your garage is a major fire hazard and creates dangerous fumes that can enter your home.

Weather Exposure

You have to go outside in the freezing rain or wind to pour fuel, risking spills and personal injury during severe weather.

Unlimited Power

Never Refuel Again

By installing a dedicated gas-line-for-generator, you tap into the underground utility lines that already power your furnace and water heater. As long as the city gas is flowing, your generator keeps running. We size the pipes perfectly to ensure your generator gets the fuel pressure it needs without starving your other appliances. If you are ready to ditch the red gas cans forever, get started with a free plumbing consultation today.

Perfect Sizing

We calculate BTUs to prevent engine starvation.

Safety Valves

We install code-required shut-off valves

Our Process

Reliable Fuel in 4 Steps

Load Calculation

We total the BTU requirements of your home’s appliances and your generator to determine the correct pipe diameter.

Trenching & Piping

We neatly run the gas line (underground or along the exterior) from your meter to the generator location.

Connection

We install the sediment trap, shut-off valve, and flexible connection hose, ensuring a vibration-resistant hookup.

Pressure Test

We pump air into the new gas-line-for-generator and monitor the gauge to guarantee there are absolutely no leaks.

Why Switch to Natural Gas?

Infinite Run Time

During extended outages like the 2021 freeze, natural gas lines kept flowing while gas stations ran out of fuel.

Cleaner Burning

Natural gas burns cleaner than gasoline, resulting in less engine buildup and fewer exhaust fumes around your home.

Cost Effective

Natural gas is significantly cheaper per gallon equivalent than gasoline, saving you money during long blackouts.

Safety Warning

Don't Trust A DIY Gas Job

Natural gas is explosive. An undersized pipe can ruin your generator engine, and a loose fitting can destroy your home. Plumbing a gas-line-for-generator requires a license and a permit for a reason. Don't risk a gas leak to save a few dollars. If you smell rotten eggs or suspect a leak in your current setup, please visit our contact page immediately for emergency repairs.

FAQ About Generator Gas Lines

Got questions? We’ve answered the most common ones below to help you stay informed and confident in your next repair or replacement.

Can any portable generator run on natural gas?

Not out of the box. Most are gasoline-only. You need a "Tri-Fuel" generator or a conversion kit to use a gas-line-for-generator. We can help you identify if your unit is compatible.

Do I need a permit?

Yes. The City of McKinney requires a permit and inspection for any extension of your gas plumbing system. We handle all of this paperwork for you.

Will running the generator starve my furnace?

This is why professional sizing is critical. We perform a load calculation to ensure your gas meter supplies enough volume for your furnace, water heater, and generator to run simultaneously.

How much does it cost?

Cost depends on the length of the run and whether we need to trench underground. We provide flat-rate, upfront pricing. You can contact us for a free site evaluation.
