CSST Gas Line Installation in Longmont, CO
Corrugated stainless steel tubing offers flexibility and can be installed with fewer fittings, often reducing installation time. Our team is certified in CSST installation, including the bonding and grounding code requires. CSST is a common choice for new gas lines or extensions because it routes easily and tolerates building movement, making it a practical option for many Longmont, CO homes.
CSST Flexible Gas Piping in Longmont, CO
Corrugated stainless steel tubing installs faster than black iron and routes easily through attics and finished walls with fewer joints. It is a smart option for remodels and additions where opening walls is costly. Sudden summer thunderstorms bring flash flooding and hail, and heavy runoff can back up storm drains and sewer lines. CSST must be bonded to the home's grounding system to reduce lightning damage risk. We use brands with fittings our plumbers are certified to install and follow the manufacturer's instructions.
