Gas Water Heater and Tankless Line Upgrades in Hattiesburg, MS
Tankless water heaters often need up to 199,000 BTU, far more than the 40,000 BTU a typical tank heater uses.

This upgrade is one of the most important steps in a successful tankless conversion.

Enhance your outdoor living space with a new gas line for a grill, fire pit or patio heater.

Frequently Asked Questions About Gas Line Installation in Hattiesburg
The cost of gas line installation in Hattiesburg, MS varies widely depending on the length of the line, the piping material, routing complexity and the number of appliances. A simple appliance hookup might range from $400 to $800, while a whole-home installation could be several thousand dollars. We provide a clear estimate after an on-site assessment.
Yes, a permit is almost always required for any new gas line installation or significant change to an existing gas system. This confirms the work is performed to code and inspected for safety. We handle the permitting process in Hattiesburg on your behalf to ensure compliance.
Most residential gas line installations for a single appliance can be completed in a few hours to one day. More complex projects, such as extending lines for outdoor kitchens or multiple appliances, might take one to two days. This timeline does not include permitting and inspections, which can add several days to the overall process.
The most common sign of a gas leak is the smell of rotten eggs, which comes from an additive called mercaptan. Other signs include a hissing sound near a gas line, dead vegetation over an underground gas line or an unexplained increase in your gas bill. If you suspect a leak, get out immediately and call 911 and your gas company.
We use respected brands for gas line components, including Gastite and TracPipe for CSST, and high-quality black iron pipe from reputable manufacturers. We also install reliable shutoff valves and fittings from brands like Mueller and Nibco for durability and safety.
Yes, we install propane lines from the tank regulator to your appliances. Propane appliances need the correct orifices and regulators, which we confirm during installation.
Gas lines generally do not need frequent inspections once installed correctly, but it is good practice to have them checked during routine plumbing inspections or if you notice unusual smells or sounds. Newer houses and manufactured homes typically rely on PEX or CPVC supply lines with PVC drains. For older homes in Hattiesburg, an inspection every 5 to 10 years can help identify potential issues.
We mainly install black iron pipe and corrugated stainless steel tubing, or CSST. Black iron is a traditional, rigid option, while CSST offers flexibility and faster installation. Both are safe and code-compliant when installed by licensed professionals, and the choice usually depends on the application and property layout.
