Why Choose HGR Plumbing for Gas Water Heater Replacement in Marietta, GA?
Homes farther south often draw from deep limestone aquifers, so more mineral-heavy water and the occasional sulfur smell are common complaints there. Sediment that settles in the bottom of gas tanks overheats the steel and cuts tank life. We set up each new heater so sediment can be flushed and the anode rod can be checked.
- Code Upgrades, We bring straps, venting, drain pans and relief lines up to current code during the swap.
- Quality Brands, We partner with leading manufacturers like Rheem, Bradford White and A. O. Smith, so you receive a durable and efficient gas water heater.
- Safety First, Gas appliances require careful handling, and our technicians are thoroughly trained in all safety protocols and code requirements for gas water heater installation.

Standard Vent Gas Water Heater Replacement in Marietta
Many homes in Marietta use standard atmospheric vent gas water heaters. When these units reach the end of their lifespan, typically 10 to 12 years, we provide professional replacement. Our service includes safely disconnecting the old unit, installing a new, energy-efficient model, and connecting it properly to your existing natural gas line and flue venting system. We also check for adequate combustion air and perform a thorough leak test for safety and efficiency.

A. O. Smith Gas Water Heater Services in Marietta
HGR Plumbing provides expert installation and replacement of A. O. Smith gas water heaters throughout Marietta. A. O. Smith is a respected brand known for innovative features and robust construction. We handle all aspects of the replacement, including correct sizing, gas line connections and exhaust venting. Our goal is to provide you with a long-lasting, efficient hot water solution matched to your home.
Power Vent Water Heater Replacement in Marietta
Power vent gas water heaters use an electric blower to push exhaust through PVC pipe, which lets them sit far from a chimney or roof flue. When the blower motor or pressure switch fails again and again, replacing the whole unit can be the better choice. We install new power vent models and confirm a dedicated outlet is available. Venting length and number of elbows must stay within the manufacturer's limits. Power vent tanks cost more but solve difficult placement problems.
Large Capacity 75 Gallon Gas Heaters in Marietta, GA
Big families, soaking tubs and multiple showers running at once often need a 75 gallon tank or a high-recovery 50 gallon model. These heaters use larger burners, sometimes 75,000 BTU, and may need a bigger gas line and flue. We check your meter and pipe size to make sure the larger tank gets the gas it needs. A high-recovery unit can be a good middle ground when space is tight. We walk you through recovery rates so you choose the right fit.
Rheem and A.O. Smith Gas Water Heater Replacement in Marietta, GA
We install and replace Rheem and A.O. Smith gas water heaters throughout Marietta, GA. These brands are industry leaders, offering a wide selection of efficient and long-lasting models. Our technicians are factory-trained on the latest technologies from Rheem and A.O. Smith. You get a proper setup that maximizes your new water heater's performance and lifespan.
Power Vent Gas Water Heater Installation in Marietta, GA
For homes in Marietta, GA where traditional venting is not possible, or for those wanting higher efficiency, power vent gas water heaters are an excellent choice. These units use a powered fan to exhaust combustion gases, offering more flexibility in installation location. Our technicians are skilled in installing these more complex systems. That includes running new PVC vent piping and making proper electrical connections for the blower motor, all while following local codes.
Atmospheric Vent Tank Upgrades in Marietta, GA
Most older homes have atmospheric vent water heaters that rely on natural draft up a metal flue. We inspect the flue pipe for rust, proper slope and correct connector size during replacement. A loose or undersized vent can leak exhaust into the garage or closet. We replace damaged vent sections and draft hoods as needed. Then we test draft with the burner running before leaving.
