About two-thirds of Johns Creek homes were built between 1980 and 1999, so many original tank water heaters and gas lines are due for a look. A tankless conversion here needs a city Trade Permit for the plumbing and gas work. Call the number on this page to be connected with a local plumber in Johns Creek.
Why are so many Johns Creek homes switching heaters now?
Age. The median Johns Creek home was built in 1995, and about 67% went up between 1980 and 1999. A water heater in those subdivisions is often on its second or third tank, and owners replacing one frequently consider tankless for the endless hot water and the floor space. The usual locations, a garage, basement or attic platform, each affect the plan. Garage and basement units can vent out a nearby wall; attic installs bring their own access and drainage questions. Large homes with four or more bathrooms sometimes need two units linked together, or one unit plus recirculation, to keep steady temperatures when several showers run at once.
What permit does the city require?
Johns Creek requires a Trade Permit for any electrical, gas, mechanical, plumbing or low-voltage system work. A tankless conversion touches several of those at once, since it involves water connections, gas piping, venting and an electrical outlet. Applications go through the city's Customer Self-Service portal, and the permit technicians can be reached at 678-512-3250. The installing plumber typically files and schedules the inspection.
How does Fulton County water affect a tankless unit?
Johns Creek is served by Fulton County Water Services, which treats Chattahoochee River water at the Tom Lowe plant, located in Johns Creek. The water is disinfected with chlorine and fluoridated, and the county report does not list hardness. A home test is the best way to decide how often to flush the heat exchanger. Fulton also offers a service line lookup at fcpwleadcopper.com. Many Johns Creek homes also have an irrigation system; that is a separate line from the water heater and does not change the tankless install.
Gas pipe sized for a 1990s tank and furnace is the most common surprise. A tankless burner draws much more at full fire, so the plumber may run a larger line from the Atlanta Gas Light meter.
Local note
If you smell gas near any appliance, leave the house first, then call 911 and Atlanta Gas Light at 877.427.4321 from a safe place.
