Water heater repair in Savannah, GA

Floridan wells and Abercorn Creek

City of Savannah Water Resources has leaned on the Upper Floridan aquifer for well over a century, drawing from a network of deep wells spread around Chatham County. That limestone aquifer gives up water that is clear, cool and fairly mineral-rich. Pumping limits set by Georgia regulators to keep salt water from creeping into the aquifer near Hilton Head have pushed the region to use more surface water, and that comes from the city's Industrial and Domestic plant, which takes raw water from Abercorn Creek, a channel off the Savannah River north of Port Wentworth.

What arrives at your tap depends on where you live and how the system is blended that week. Neighborhoods fed straight from wells see moderately hard water with a steady temperature near 70 degrees, which is kind to heater recovery but leaves a gritty layer of calcium in the bottom of a tank. Areas that get more creek water see softer, more variable water that runs colder in January. Some Floridan wells also carry a whiff of hydrogen sulfide, and a heater can amplify that into a sulfur smell on the hot side only.

Squares, carriage houses and Southside slabs

Inside the Landmark Historic District, the homes around Chatham, Pulaski, Monterey and the other squares are mostly brick and stucco row houses and townhouses built over raised ground floors. Owners call that lower level the garden level, and it is where many water heaters ended up, often in a closet beneath the front stoop. Behind those houses, carriage houses on the lanes have been turned into rentals and short-term stays, each with its own small tank or a tankless unit hung on a wall.

South of Forsyth Park, the Victorian District, Thomas Square and Starland hold wood-frame houses on piers with heaters in back porches enclosed decades ago. Ardsley Park, Parkside and Baldwin Park are early twentieth-century neighborhoods of bungalows and revival homes, frequently with a tank in a hall closet or a detached garage. Farther out, Windsor Forest, Georgetown and the Southside subdivisions are slab ranches from the 1960s onward with heaters in garages and utility rooms.

Hurricanes, surge and Savannah power outages

Hurricane Matthew in 2016 and Irma a year later brought flooding to low parts of Chatham County, and Debby in 2024 stalled overhead and dumped enough rain to swamp streets on the Southside and in neighborhoods along the Casey Canal. Helene that same year knocked out power across much of coastal Georgia for days. A gas tank keeps heating through an outage if it has a standing pilot, while electric tanks and most tankless units sit idle until Georgia Power restores the line.

Garage and garden-level heaters are the ones most likely to sit in floodwater. Once a tank's burner chamber, gas valve or lower element has been underwater, leave it off until a plumber has looked at it, and expect the controls to be swapped. Owners on Wilmington Island, Isle of Hope and other marsh-edge areas sometimes raise the heater on a platform or move it up a floor during a replacement, which is worth pricing while the old one is coming out anyway.

The problems plumbers see most in Savannah

• Calcium grit from Floridan well water packed into the bottom of tanks, causing popping and slow recovery.
• Sulfur odor on the hot tap where a magnesium anode reacts with traces of hydrogen sulfide.
• Garden-level closets under stoops where a leaking tank soaks old brick and plaster before anyone notices.
• Storm-damaged controls on gas valves and elements after surge or street flooding.
• Carriage-house rentals with undersized tanks that guests drain in one long shower.
• Humid attic and porch installs where rust attacks fittings, flue pipes and the jacket.

Typical water heater prices in Savannah

Work inside the Historic District tends to land in the upper part of each range, mostly because of parking, narrow lanes and stairs down to the garden level. A plain garage swap on the Southside or in Pooler usually comes in lower.

Georgia licensing and Savannah permits

Georgia's State Construction Industry Licensing Board has a plumbing division that issues master and journeyman cards, and a Savannah homeowner can search a contractor's name in the Secretary of State's online lookup. Within the city, Savannah's Development Services office permits each heater swap, and its inspector looks over the relief line, the gas piping, the vent and any required pan. Unincorporated areas like Wilmington Island and Georgetown go through Chatham County instead.

If a replacement changes the outside of a building in the Landmark Historic District, for instance a new wall vent for a tankless unit or a condensing heater facing the street, the change may need review under the city's historic preservation rules. A good local contractor knows to route vents toward the lane or side yard where that is possible.

Taming the sulfur smell

When only the hot water smells like eggs, the source is nearly always inside the heater. Sulfate-reducing bacteria thrive in a warm tank, and the reaction with a magnesium anode turns small amounts of sulfur in Floridan water into hydrogen sulfide gas. Swapping to an aluminum-zinc anode or a powered anode usually solves it, and a flush with the heater briefly run hotter can clear the bacteria. Be careful raising the temperature in homes with small children, and set it back afterward.

If the cold side smells too, call Savannah Water Resources so they can check the line; that points to the water supply or the building's plumbing rather than the heater.

Short-term rentals and carriage houses

Savannah's vacation rental market fills carriage houses and garden apartments with guests who shower back to back after a long walk through the squares. Many of these units were plumbed with a 30 or 40 gallon electric tank tucked into a laundry nook. When reviews start mentioning cold showers, owners have a few options: a taller tank with faster elements, a compact gas tankless unit if gas runs down the lane, or a heat pump heater where there is enough room and air.

Whatever you choose, a drain pan piped outdoors and a leak sensor matter more in a unit that sits empty between bookings, because a slow drip can run for days before the next guest or cleaner walks in.

Repair or replace in a Savannah home

On Floridan well water, the steel of a tank lasts reasonably well, and many heaters reach ten to twelve years with an occasional flush. On a tank younger than eight, a bad igniter, thermocouple, element or relief valve is a quick, affordable fix. Once a tank is leaking from the shell, or rust shows in the hot water, replacement is the only real fix.

Georgia Power and the gas marketers that sell service over the Atlanta Gas Light system have offered rebates and efficiency programs at times; look up this year's offers first. A heat pump heater makes good sense in a large Southside garage, where Savannah's long warm season keeps it running efficiently and it dehumidifies the space as a bonus. Sizing and fuel choices are covered in the replacement guide.

Around Savannah

Pooler and Port Wentworth have grown quickly along I-95 and the port, and each runs its own building department. Richmond Hill in Bryan County and Rincon in Effingham County handle their own permits and water systems. Tybee Island has a city water system and an island's worth of salt air that corrodes outdoor heaters and vents. Garden City and Thunderbolt are separate cities as well, so the permit office changes when you cross their lines.
