Licensed gas line work done right new installations, extensions, appliance hookups, and pressure testing. O5 Plumbing is your certified gas line contractor for scheduled residential and light commercial gas work in the San Antonio area.
In Texas, gas line installation and repair requires a licensed plumber or gas fitter. That's not a formality it's a safety standard. Natural gas and propane systems operate under pressure, and an improperly installed fitting or an untested connection can leak invisibly inside walls for months before creating a hazardous situation.

We pull permits where required and coordinate with CPS Energy inspections so your work is done by the book.
Every new gas line installation and repair is pressure tested before being placed into service. We verify zero pressure drop before we sign off on any gas work.

Straight answers about scheduled gas line work.
Yes. New gas line installations and extensions within the City of San Antonio require a permit and inspection. O5 Plumbing pulls the necessary permits on your behalf and coordinates the required city or CPS Energy inspection. Unpermitted gas work can create problems when you sell your home and may void your homeowner's insurance coverage.
Gas lines are run in black iron pipe, corrugated stainless steel tubing (CSST), or approved flexible connectors depending on application. CSST is now the most common choice for new residential work it's flexible, easy to route, and meets current code. Black iron is still used for exposed installations and certain commercial applications. The final connection to an appliance uses a listed flexible gas connector.
Yes this is one of our most common requests. We run a dedicated line from your existing gas supply to the outdoor location, install a manual shutoff valve at the outlet, and pressure test the completed run. Converting from propane tanks to a permanent natural gas line is a cost-effective upgrade for homeowners who use their outdoor cooking setup regularly.
We pressurize the isolated pipe section with air or inert gas to a level above normal operating pressure, then monitor it with a calibrated gauge for a set time period. Any pressure drop indicates a leak that must be located and repaired before the system is placed into service. We never skip this step a passed pressure test is required before we consider any gas job complete.
