Gas Water Heater Repair & Installation in Doraville, GA

Replacing a gas water heater is a sequence of steps that each have to happen in the right order, and knowing them makes it easier for Doraville homeowners to plan the day. When Alpha Plumbing and Sewer replaces one gas tank with another, the job unfolds in a predictable way, from the first phone call to the first hot shower.

Before the visit

• Find the rating plate on the old heater and note its capacity, its gas type and whether it vents through a metal pipe on top or through plastic pipe with a blower.
• Clear a path from the door to the heater wide enough for a tank on a hand truck.
• Move stored items well away from the heater and its shutoff valves.
• Plan for the household to go without hot water for part of the day.

The paperwork in Doraville

Doraville asks for a notarized affidavit with every permit, signed by the owner, and the city's residential permit checklist lists new plumbing lines and fixture work that changes piping among the jobs that need one. Whether a straight swap needs a permit is worth confirming with the city; if it does, getting the affidavit notarized early keeps the schedule moving.

Shutting down and removing the old heater

1. Turn the gas control to off and close the gas shutoff valve on the supply line.
2. Close the cold water supply to the heater and open a hot tap to relieve pressure.
3. Drain the tank through its drain valve with a hose run to a floor drain or outdoors; a tank full of sediment can drain slowly.
4. Disconnect the gas connector, the water lines and the vent connector, then carry the old heater out.

Setting and connecting the new heater

1. Set the new heater level, in its pan if one is used, keeping the clearances printed on the label.
2. Connect the gas supply with a sediment trap and a new connector, then leak-test every gas joint.
3. Connect the cold and hot water lines, often with new flexible connectors, and with dielectric fittings where copper meets steel.
4. Run the relief valve discharge pipe to an approved termination.
5. Fit the vent connector to the draft hood or blower with proper slope, support and joints.

Filling, lighting and checking

The tank is filled with a hot tap open until water runs steadily without sputtering air, because firing an empty tank can damage it. Only then is the pilot lit or the electronic ignition started, following the manufacturer's lighting instructions. We watch the burner through a full heating cycle, confirm that exhaust drafts up the vent, set the thermostat with you and recheck every connection for drips. Removal of the old heater is listed in the estimate, and you receive the model and serial numbers for registering the manufacturer's warranty.

When the day takes longer

A straight swap is the simplest case. Corroded shutoffs that will not close, a vent that does not suit the new heater, an undersized gas line or a new model too tall for the space can each add work, so we look for those issues while preparing the estimate. A stuck cold water shutoff can be replaced as part of valve repair before the heater goes in. Picking a tankless water heater or an electric water heater instead changes several of these steps; our Georgia water heater overview describes what differs.

Installation day questions in Doraville

How long will we be without hot water?

Plan on several hours for a straightforward replacement, counting from draining the old tank to the new one reaching temperature. Most of that time goes to draining, connecting and waiting for the new tank to heat. Complications such as a stuck valve or vent changes add time, and we tell you before work starts if we expect any.

Do I need to be home during the installation?

Someone should be there at the start to give access and point out the shutoffs, and again at the end to see the heater running, learn how to adjust the temperature and confirm where the gas and water shutoffs are. In between, the work can usually carry on without you, as long as the path to the heater stays clear.

What happens to my old water heater?

Taking the old tank away is normally part of a replacement, and the estimate should say so plainly. It is drained before it leaves the house so it can be carried out without spilling. If you want to keep it for any reason, tell us beforehand, since it can stay heavy with sediment even after draining.
