Frequently asked questions
How do I know if I have a gas leak?

Do I need a permit for gas line work in San Marcos?
Yes, most gas line installations, repairs, and alterations in San Marcos require a permit from the city's development services department to ensure compliance with safety codes.
What is CSST and is it safe?
CSST (Corrugated Stainless Steel Tubing) is a flexible gas piping material often used for its ease of installation. It is safe when properly installed and bonded/grounded to protect against lightning strikes.
