Frequently Asked Questions

Can a plumber install gas lines?
In most states, licensed plumbers are authorized to install gas lines. Some states require a separate gas fitter license.
Is CSST better than black iron pipe?
CSST (flexible gas tubing) is faster to install and costs less for long runs. Black iron is more durable but labor-intensive.
How is the line tested?
After installation, the line is pressure-tested with air or nitrogen and checked for leaks before the gas is turned on.
Can I extend an existing gas line myself?
No. Gas line work is dangerous and requires professional installation, permits, and inspection in all jurisdictions.
