Rheem 50-Gallon Natural Gas Water Heater Replacement in Marietta

October 27, 2026

Rheem 50-gallon natural gas water heater replacement in Marietta

BF Plumbing & Drain, Inc. completed a water heater replacement at a home in Marietta, installing a Rheem 50-gallon natural gas unit and updating the associated water connections. The project called for removing the existing heater, furnishing the replacement, and completing the installation through startup and testing. Our crew also installed a supported thermal expansion tank, a new cold-water shutoff valve, and a drain pan. After filling the tank and purging air from the water lines, we ignited the burner, checked the water and gas connections for leaks, and verified operation. The finished job included disposal of the old unit and cleanup of the work area.

A Complete Water Heater Replacement for This Marietta Home

The customer's project was a replacement rather than a repair to the existing water heater. The documented scope covered both the new appliance and the installation materials needed to connect it to the home's plumbing. It also included equipment, labor, and removal of the old heater, keeping those tasks together as one job.

Marietta is the county seat of Cobb County, about 15 miles northwest of Atlanta. For this local project, the important installation details were specific to the home: the existing water connections, gas supply, exhaust venting, and relief-valve discharge piping all had a role in connecting the replacement unit.

Our water heater replacement services include the work around the tank as well as the tank itself. Here, the scope identified a 50-gallon natural gas model, hard copper water piping, a new expansion tank, and a new shutoff valve, giving the installation a clearly defined set of components.

Removing the Existing Heater and Connecting the Rheem Unit

Our crew removed the existing water heater and furnished and installed the new Rheem 50-gallon natural gas water heater. Disposal of the removed unit was part of the completed work, so the old appliance was not left at the property for the customer to handle separately.

The replacement used the home's existing gas supply and exhaust venting, with reconnection included as applicable. The scope also addressed reconnecting the temperature and pressure relief valve discharge piping. These connections serve different functions from the hot and cold water lines and were part of the overall replacement work.

This project can also be compared with our Rheem 40-gallon natural gas water heater replacement in Roswell. Both projects involved Rheem natural gas units, while this Marietta installation used a 50-gallon model. The capacity is a meaningful distinction between the two completed jobs, without implying that the same tank size suits every property.

New Expansion Tank, Support Bracket, and Cold-Water Valve

A new 2-gallon thermal expansion tank was included in the installation. Our crew installed it with a support bracket and pressurized it to match the home's water pressure. Matching that pressure was an installation step specific to the system, rather than simply fitting the tank and leaving its pressure unaddressed.

The expansion tank accommodates water expansion as the water heater heats its contents. Its role is separate from the main tank's storage capacity: the Rheem unit stores and heats water, while the smaller expansion tank handles that change in volume. The support bracket was another specified part of this assembly.

We also installed a new 3/4-inch brass ball valve on the cold-water supply. That valve provides a shutoff point for the incoming water at the heater. Including it in the replacement addressed an important service connection alongside the new tank and expansion components.

Hard Copper Connections and a New Drain Pan

The hot and cold water connections were addressed using hard copper piping, with reconfiguration as necessary for the replacement. This portion of the work connected the new water heater to the home's existing water lines. It was a defined part of the job rather than a separate whole-home piping project.

Pipe connections deserve attention during a water heater replacement because the appliance and the surrounding plumbing must work together. For customers with concerns elsewhere in their water lines, our pipe and leak services address that related category of work. This project's documented piping scope remained focused on the heater's hot and cold connections.

A new water heater drain pan was also installed. The pan was part of the replacement materials, distinct from the relief-valve discharge piping and the water-supply connections. Together, these details show why a water heater replacement involves more than exchanging one storage tank for another.

Filling, Burner Startup, and Connection Checks

Once the installation connections were complete, our crew filled the water heater and purged air from the water lines. These steps brought water into the replacement tank and cleared air introduced during the work. We then ignited the burner as part of putting the natural gas unit into operation.

The completion process included testing all water and gas connections for leaks and verifying proper operation. Those checks addressed the assembled installation, including the connections made during the replacement. The documented result was a new water heater placed into operation after startup and testing.

Our crew finished by cleaning the work area. Along with removal and proper disposal of the existing heater, this closed out the on-site scope. The customer was left with the replacement unit installed and the installation work completed.

Warranty Coverage and Related Plumbing Needs

The new water heater carries a 9-year manufacturer's limited tank warranty. This project also includes a 1-year BF Plumbing & Drain labor and workmanship warranty. These are separate coverage descriptions: the manufacturer's stated coverage concerns the tank, while the company's stated coverage concerns labor and workmanship.

For future service conversations, the useful project details are the Rheem brand, 50-gallon capacity, natural gas fuel type, and newly installed expansion tank and shutoff valve. Customers with separate needs at sinks, faucets, or other indoor fixtures can also review our fixture and indoor plumbing services; those services are distinct from the work recorded here.

This Marietta project brought the replacement tank, supporting components, startup, and cleanup into one completed installation. To connect with the business about a similar project, visit BF Plumbing & Drain, Inc. on Google or call 404-706-2958.
