Gas line upgrades

What to expect during installation
A licensed plumber will first assess your existing setup and obtain the required permit. The job typically takes 3–6 hours for a standard tank replacement, longer for tankless or if gas line work is needed. After installation, the plumber will test the system and schedule a city inspection to ensure code compliance.
