Grayson is one of the youngest cities in Gwinnett, with a median home built in 2012, so many water heaters are originals now nearing replacement age. Gas for city residents comes through City of Lawrenceville Utilities, which matters for any gas water heater swap. Call the number on this page to be connected with a local plumber in Grayson.

Are Grayson water heaters really wearing out already?
Some are. Grayson grew from 765 residents in 2000 to 4,730 in 2020, and only about 3.9% of homes predate 1980. Builder-grade tanks installed during that growth are now well into their second decade, and units that were never flushed may already be rumbling or leaking. A tank that leaks from its body, gives rusty hot water or runs out early is ready to be replaced.
Which gas utility handles a Grayson heater swap?
Grayson's New Resident page says gas for city residents comes through the City of Lawrenceville Utilities. If you smell gas, leave first, then call 911 and the City of Lawrenceville gas emergency line at 770-963-3332 from a safe place. Confirm the utility on your gas bill, since some addresses near the city may be served differently. When a gas heater is replaced, the installer shuts off the supply at the appliance, reconnects with a new connector and checks for leaks.
Who issues the permit, and what about the water?
The City of Grayson takes building permit applications through its own online portal, and City Hall is at 475 Grayson Parkway, 770-963-8017. The city does not say whether plumbing-only or water heater permits use the same portal, so ask the plumber to check with City Hall.
Gwinnett County is the water utility, with Lake Lanier water treated at the Shoal Creek and Lanier plants. Gwinnett lists total hardness around 1.05 to 1.87 grains per gallon, which is soft, so scale is not a big local issue. Gwinnett is responsible for the pipes to the meter; the homeowner owns everything from the meter to the house.
One Grayson note
Because so many homes are newer, heaters often sit in attics. A pan and drain line under the new tank, and a relief line routed to code, are worth confirming in the quote. Have the heater's size, fuel and age ready when you call, and ask whether the price includes hauling away the old tank. If you are open to a tankless or heat pump model, ask for those prices on the same visit.
