Gas Piping

THE SHORT ANSWER
If you smell gas, get everyone out and call your gas utility first, then call us for the line. For everything else, gas piping is a permit-and-pressure-test job: new lines for a range, water heater, central heater, outdoor kitchen, pool heater or generator, plus repairs, replacements and CSST testing. Hargrave’s sizes the line for the full appliance load, pressure tests it and pulls the permit, to Louisiana code.

How a gas line is done properly

What every gas job includes

Gas work is the one place where there is no shortcut worth taking. This is the procedure on every line we run.
Full appliance load calculated, including anything you plan to add later
Meter and regulator capacity checked, with 2 pound systems used where the run demands it
Pipe material and diameter sized to the run length, not to what is on the truck
Routing planned around structure and grade, with sleeving and boring under drives where needed
CSST bonded and inspected, because lightning pinholes are a real risk in Acadiana
Full pressure test and leak check on the whole system before anything is lit
Permit pulled and inspection coordinated with the city or parish
Every appliance lit, checked and left working before we leave
Every gas line run is priced in person: length, pipe size and access set the number, and boring under concrete is priced per job.

Pressure tested and permitted · 24/7 emergency response.

Why gas piping is different here

Lightning and CSST
Corrugated stainless tubing is common in newer Acadiana homes and it can develop pinholes from a nearby lightning strike if it was never bonded properly. We test for it and we offer the correction.
Generators changed the math
A standby generator can double the gas demand on a house. Lines that were correct in 2010 are undersized once a generator is added, and that is why some units drop out under load.
Wet ground and buried line
Buried gas line in soil that stays wet corrodes from the outside. We check the condition rather than assuming an old line is fine.

How a gas piping job goes

  1. You book
    Online or by phone, 24/7. For any gas odor, leave the building and call your gas utility first.
  2. We size the whole system
    Every appliance, existing and planned, against the meter and the run length. This is where undersized lines get caught.
  3. You see the price, then we start
    Priced in person, permit included in the plan. The price you approve is the price you pay.
  4. Tested, inspected, lit
    Full pressure test, inspection, then every appliance lit and checked with you before we go.
24/7 EMERGENCY · EVERY CALL ANSWERED

Gas smell at 2am? Leave, call the utility, then call us.

Life safety first: get everyone out and let your gas utility shut it off. Then call us at any hour, your call is answered, and we handle the line repair and the pressure test.

Gas questions we get every week in Lafayette and Youngsville

I smell gas. What do I do first?
Get everyone out, do not flip switches or light anything, and call your gas utility so they can shut it off at the meter. Once it is safe, call us for the leak location and the repair.
What does a new gas line cost?
It depends on length, pipe size and access, and boring under concrete is priced per job. We price it in person before any work begins, so the number is accurate.
What is CSST and why does bonding matter?
CSST is the flexible corrugated stainless tubing used in a lot of newer homes. If it was not bonded to the electrical ground, a nearby lightning strike can arc to it and leave a pinhole. In a lightning-heavy place like Acadiana that is worth testing for.
Do I need a permit?
Yes for new lines and most alterations, and we pull it. Permitted, pressure tested and inspected is the only way gas work should be signed off.
Assurance Plan members go first.
Annual water heater flush, priority scheduling, and two inspections a year.
