The backyards around Keller have gotten serious. Built-in grills, pizza ovens, gas fire pits, pool heaters, and standby generators that click on before the neighbors’ lights even flicker. Every one of those runs on natural gas, and every one of them means a new line, a permit, and a question almost nobody asks first: can your meter even feed it?
That last question is the whole ballgame, and it is the reason we lead with an assessment instead of a price. You can run beautiful pipe to a gorgeous outdoor kitchen. If the meter and the line back to it cannot deliver the fuel, you get a grill that starves the moment the pool heater kicks on. This is not a project where the pretty part is the hard part. The pretty part is easy. The gas math is the job.
This guide covers what these projects actually involve, why the meter matters more than the pipe, what each appliance demands, how the permit and Atmos coordination work, and the one safety rule that never bends. In June alone we ran several thousand dollars of this exact work around Keller, including a fire pit line, so this is our busy season talking.
Why Your Gas Meter Decides the Whole Project
Here is the thing the cost-per-foot articles skip entirely. Your home’s gas system is not bottomless. The meter has a rated capacity, and every gas appliance in the house, the furnace, the water heater, the range, the dryer, draws against that same budget at once.
Add a built-in grill, a fire pit, and a pool heater to a system sized years ago for just a furnace and a water heater, and you may simply run out of gas, literally. The symptom is not a dramatic failure. It is a fire pit that will not reach full flame while the furnace runs, or a generator that struggles the moment the AC and the water heater are both going. Everything is installed perfectly. There is just not enough fuel to go around.
So the first move on any of these jobs is measuring the demand you are adding against the capacity you have. Sometimes the existing line and meter have plenty of headroom, and the job is a clean extension. Sometimes the line from the meter needs upsizing. And sometimes the meter itself is the bottleneck, which means coordinating an upgrade with Atmos Energy, the gas utility here. We handle that coordination as part of the project. This is the same capacity math that makes or breaks a tankless conversion, which our tankless water heater cost guide covers, and it is why a real quote follows an assessment, never a phone call.
What Each Backyard Appliance Actually Demands
Not all gas projects are equal. The appliance sets the difficulty, because the appliance sets the fuel demand.
Gas fire pit. Usually the friendliest of the bunch. A fire pit’s burner is real but modest, so if the meter has headroom, this is often a clean extension to a nearby point with a proper shutoff. The fire pit we ran in June was exactly this kind of job.
Built-in grill or full outdoor kitchen. A single built-in grill is manageable. A full outdoor kitchen, grill plus side burner plus maybe a pizza oven, stacks demand and usually needs a properly sized run, sometimes back to the meter. The more burners, the more the capacity question matters.
Pool heater. A quiet giant. Pool heaters have some of the largest gas appetites in the backyard, often more than everything else combined, and they are the appliance most likely to reveal that a meter is undersized. Never assume a pool heater drops onto an existing line.
Standby generator. The special case. A whole-home generator does not just add demand, it demands fuel at the worst possible moment, during an outage when it may be running alongside the furnace or AC. Sizing has to account for the generator plus household load running together, and larger units need a substantial supply line. This is the appliance where cutting the pipe size to save money guarantees a generator that stalls exactly when you needed it.
The pattern: fire pits and single grills are often extensions, while pool heaters, generators, and full kitchens are capacity projects. The assessment tells you which one you have.
Permits, Inspection, and Why This Is Never DIY
Every one of these projects needs a permit and an inspection, full stop. A permanent gas line tied into your home’s supply is licensed work in Texas, performed by a licensed plumber or gas fitter and inspected before it is ever used. A portable propane tank on a freestanding grill is the only version that skips this, because it is movable equipment, not a hard connection.
This is not red tape for its own sake. The reasons are real money and real safety. Unpermitted gas work commonly voids your homeowners insurance, so a fire traced to a line you ran yourself can turn a claim into a denial. It surfaces at resale too. A buyer’s inspector flags the unpermitted line, and the sale stalls until it is opened up, inspected, and re-permitted, on your dime. And most seriously, a gas leak is not a drip that stains a ceiling. It is a fire and explosion risk. Our gas line repair guide for Keller TX covers the repair side of that same principle.
The permit also protects you from the installer. A permitted job gets a city inspector’s second set of eyes on the work, which is exactly the accountability you want on a system that can level a house.
How We Build One, Step by Step
The sequence is the same whether it is a fire pit or a generator, and it is built around never guessing on gas.
First, the assessment: we measure your meter’s capacity and total the demand of everything on the system plus what you are adding. That tells us whether the job is an extension, a line upsize, or a meter upgrade with Atmos. Second, the route and materials: we plan the path, size the pipe to the load and distance, and choose the right material. Outdoor runs get buried to proper depth, and every appliance gets its own accessible shutoff valve. Third, the permit, pulled before we start. Fourth, the install and the pressure test, because every joint gets tested and checked before gas ever flows, no exceptions. And fifth, the city inspection and your written summary, so you have proof the work is right and safe.
Texas 811 comes first on any digging, always, to locate existing utilities before a shovel moves. And where a meter upgrade is needed, the Atmos coordination is ours to manage, not a homework assignment we hand back to you.
Polly Plumbing is a locally owned shop on Keller Parkway. We install, extend, and pressure-test gas lines across Keller and Tarrant County, and every quote follows an assessment, never a guess.
What It Costs, the Short Honest Version
We keep pricing in broad strokes because the meter answer changes everything. A simple extension to a nearby fire pit, on a system with headroom, is one of the friendlier gas jobs there is. A full outdoor kitchen, a pool heater, or a generator that forces a line upsize climbs from there. And a job that requires an Atmos meter upgrade is a bigger project with a utility timeline attached.
The national sites love a tidy per-foot number. It is misleading here, because it prices the easy part, the pipe, and ignores the part that actually determines your bill, whether your meter can feed the appliance. Two identical fire pits, one on a system with headroom and one that forces a meter upgrade, are completely different projects. The written quote is the invoice, the $89 dispatch fee is waived for PollyCare members, there is no emergency surcharge, and how we think about pricing generally lives in our plumber cost guide for Keller TX.
The One Rule That Never Bends: Utility First, Plumber Second
If you ever smell gas, that rotten-egg odor, or hear hissing near a gas line or appliance, this is the sequence, in this order.
Get everyone out of the house. Do not flip switches, do not light anything, do not even use your phone until you are well away, because a spark is the one thing that turns a leak into a disaster. From a safe distance, call the gas utility first. Atmos Energy’s emergency line is 1-866-322-8667, and they will come shut off and make the area safe. Then call us.
That order is not negotiable, and it is worth saying plainly even in an article about installing gas lines: the utility handles the immediate danger, the plumber handles the repair. Utility first, plumber second, every time. Program that Atmos number into your phone now, while nothing is wrong, so it is there if something ever is.
Natural Gas or Propane in Keller
Most of Keller and its neighbors run on natural gas piped in by Atmos, which is why these projects are usually extensions of an existing meter. Some outlying and rural properties, more common toward the edges of the area, run on propane instead, with a tank on the property. The appliances are similar but the systems differ. Propane runs at a different pressure and needs the right regulators and fittings, and a propane project answers to the tank and its regulator rather than a utility meter. We work with both. The assessment simply starts by confirming which one feeds your house, because everything downstream depends on it.
Around the Area
The backyard boom is not evenly spread, and neither is the capacity problem. Southlake and Colleyville lead the area on full outdoor kitchens, pool heaters, and standby generators, exactly the high-demand appliances most likely to outrun an existing meter, which makes the capacity assessment non-negotiable there. Newer construction across Flower Mound and north Keller often has a little more headroom to work with, though a pool heater can still tip it. North Richland Hills’ older homes carry the area’s smallest original gas systems, so even a modest addition there deserves the meter check first. Flower Mound permits through the Town, which we handle like Keller’s. Wherever you are, the meter answer comes before the pipe.

Frequently Asked Questions About Outdoor Gas Line Installation
How much does it cost to run a gas line for a fire pit or outdoor kitchen in Keller?
It depends far more on your gas meter than on the length of pipe. A simple extension to a nearby fire pit, on a system that already has capacity to spare, is one of the friendlier gas jobs. A full outdoor kitchen, a pool heater, or a generator that forces a line upsize costs more, and a job needing an Atmos meter upgrade is bigger still with a utility timeline. The national per-foot numbers mislead, because they price the pipe and ignore the meter. Polly Plumbing quotes after an assessment, and the written quote is the invoice. Call (817) 286-3446.
Do I need a permit to run a gas line for a fire pit or grill?
For a permanent gas line tied into your home’s supply, yes, always, with an inspection to follow. Texas requires this work be done by a licensed plumber or gas fitter. The only version that skips the permit is a portable propane tank on a freestanding grill, because that is movable equipment rather than a hard connection. Skipping the permit on a hard line risks voiding your homeowners insurance, creates problems at resale when an inspector flags it, and removes the safety check on a system that can cause a fire. Call Polly Plumbing at (817) 286-3446.
Can my existing gas meter handle a new outdoor appliance?
Maybe, and that is exactly what has to be checked first. Your meter has a rated capacity, and every gas appliance in the house draws against it at once. A new fire pit might fit easily on a system with headroom, while a pool heater or generator can exceed what the meter delivers, starving appliances when several run together. The fix is either upsizing the line or coordinating a meter upgrade with Atmos Energy. Polly Plumbing measures capacity against demand before quoting anything. Call (817) 286-3446.
Why does a generator need a bigger gas line than a grill?
Because a standby generator has a large fuel appetite and demands it at the worst moment, during an outage when it may run alongside the furnace or AC. Sizing must account for the generator plus household load at the same time, and larger units need a substantial supply line. Undersize that line to save money and the generator stalls exactly when the power is out and you needed it most. This is the appliance where the gas math matters most, which is why it always starts with a capacity assessment. Call Polly Plumbing at (817) 286-3446.
What should I do if I smell gas?
Follow one order, every time: utility first, plumber second. Get everyone out of the house immediately. Do not flip any switch, light anything, or use your phone until you are well away, because a spark can ignite the leak. From a safe distance, call Atmos Energy’s emergency line at 1-866-322-8667 and let them shut off and secure the area. Then call a plumber for the repair. The utility handles the immediate danger, the plumber handles the fix. Program that Atmos number now. For repairs after the area is safe, call Polly Plumbing at (817) 286-3446.
Is running a gas line a DIY project?
No. A permanent gas line is licensed work in Texas for good reason: a mistake is not a leak that stains a ceiling, it is a fire and explosion risk, and it must be pressure-tested and inspected. Beyond safety, unpermitted gas work commonly voids insurance and creates resale problems. The only homeowner-safe gas option is a portable propane tank on a freestanding grill. Anything hard-piped into your home’s supply belongs to a licensed plumber with a permit and an inspection. Call Polly Plumbing at (817) 286-3446.
Does a pool heater need its own gas line?
Often, effectively yes, because pool heaters have some of the largest gas demands in a backyard, sometimes exceeding everything else combined. Dropping one onto an existing line without checking capacity is how you end up with a heater that will not fire fully while the furnace or water heater runs. The right approach measures the pool heater’s demand against your meter’s capacity, then sizes the supply, upsizes the line, or coordinates a meter upgrade as needed. Never assume a pool heater fits the line you have. Call Polly Plumbing at (817) 286-3446 for an assessment.
