Johns Creek water heater failures usually trace to one part, such as an element, a thermostat, an igniter or a valve, and a plumber can generally replace it in one trip. A tank leaking through its shell must be replaced. Call the number on this page to be connected with a local plumber in Johns Creek.

My house is from the 1990s. Is the heater on borrowed time?
If it's the original, almost certainly. About 67% of Johns Creek homes were built between 1980 and 1999, and census estimates put the median build year at 1995. Most of those houses are now on their second or third heater, and a replacement installed in the 2000s or early 2010s may itself be near the end. Larger homes here sometimes have two heaters or a big tank in the attic or basement. A single failed part on a younger unit is a reasonable repair; a leaking or rusting tank in its teens is usually better replaced. In an attic install, a leak can do real damage before anyone notices, so a drain pan with a working drain line is worth confirming during any visit.
What about the water itself?
Johns Creek doesn't run its own water or sewer. Fulton County Public Works supplies both, and the water treatment plant that serves north Fulton, the Tom Lowe Atlanta-Fulton County plant, is located in Johns Creek. It treats Chattahoochee River water and disinfects with chlorine, which is relatively easy on the rubber seals in heater valves. Fulton County's report doesn't state hardness, so sediment is best judged by draining the tank. The county is responsible for the line from the main to the meter; the owner, from the meter to the house.
Does the city require a permit?
Yes, for work on the plumbing or gas system. Johns Creek requires a city Trade Permit for any electrical, gas, mechanical or plumbing work, applied for through the city's Customer Self-Service portal. A heater replacement falls under that. A simple part swap usually doesn't, and the plumber can confirm.
Local note
Atlanta Gas Light maintains north Fulton's natural gas infrastructure. If you smell gas near the heater, leave first, then call 911 and Atlanta Gas Light at 877.427.4321 from outside. For a drinking water emergency on the county side, Fulton's north Fulton line is 770-640-3040. Fulton County also keeps a lead service line inventory at fcpwleadcopper.com where you can check your line's material.
