Do You Need a New Gas Line or an Upgrade?
Gas line installation is not only for new builds. Homeowners in Lafayette, Broussard, Youngsville, Carencro, and beyond often need new lines or upgrades during remodels & equipment changes.
Common reasons to install or upgrade a gas line:
- Switching from electric to gas cooking for better control and faster heat
- Adding outdoor living features such as a permanent grill, fire pit, pool heater, or summer kitchen
- Installing a tankless water heater or high efficiency furnace that needs larger capacity piping
- Building an addition or moving appliances during a renovation
- Powering a standby generator or gas lanterns for curb appeal
- Replacing aging or corroded piping to improve safety and reliability
Warning Signs of a Gas Line Problem
Although uncommon, gas leaks are serious and knowing how to detect a gas leak will help you respond as quickly as possible.
Watch out for these indicators:
- A rotten egg odor created by an additive called mercaptan
- Hissing or whistling near a gas appliance or exposed piping
- Dead or discolored grass along a buried line
- Bubbles in standing water above a suspected underground line
- Yellow or sooty burner flames instead of steady blue flames
- An unexplained spike in your gas bill
Safety first: If you smell gas or suspect a leak, do not use electrical switches or phones indoors. Get everyone out, leave doors open, move a safe distance away, then call your gas utility and Hargrave’s Plumbing.
