Gas Line Upgrades for Water Heaters in Marietta, GA
Upgrading to a larger or tankless gas water heater may require more gas flow. We calculate total BTU demand and pipe length to size the line correctly. We install black iron or CSST piping and bond it where required. A properly sized line prevents low flame and weak performance. We pressure test new lines before service.

Atmospheric Vent Gas Water Heater Installation in Marietta
Atmospheric vent water heaters rely on natural draft to move exhaust through a metal flue. They are common in older homes and are often the most affordable gas option. We inspect the existing vent for damage, proper slope and clearance. If the vent is undersized or corroded, we replace it. Proper draft is critical for safety.

We also confirm correct pressure relief valve installation and seismic strapping where local code requires it for safety.

Installing a new gas water heater usually requires a permit and an inspection by local authorities.

We perform installations that meet or exceed all local building and plumbing codes, making sure your new gas water heater passes inspection without issue.
