A Grayson disposal that hums, won't start or leaks usually has a jam, a tripped reset, a worn gasket or a dead motor. In homes this new, it's almost always the unit rather than the drain. Call the number on this page to be connected with a local plumber in Grayson.

Why would a disposal fail in such a new house?
Grayson grew remarkably fast, from 765 residents in 2000 to 4,730 in 2020, and its homes are among the newest in the metro. Census survey figures give a median build year of 2012, with under 4% of homes built before 1980. That means modern drain lines and, in most kitchens, the builder's original disposal. Builder units are light-duty, and in a busy household they often hum, leak from the housing or trip their reset within the first decade. The drain behind them is rarely the problem, so a sturdier replacement usually solves it.
Is my Grayson home on Gwinnett sewer?
Most likely, but check. The city states that Gwinnett County is its water utility, and the city's industrial park sewer connects to the Gwinnett system. No city page states the residential sewer provider outright, and some properties may not be on municipal sewer. If yours uses a private onsite system, a disposal adds solids to the tank and grease is a problem, so use it lightly. For problems in the public sewer, Gwinnett's 24-hour dispatch line is 678.376.7000.
Where do permits come from?
The City of Grayson takes building permit applications through its own online portal, and City Hall at 475 Grayson Parkway can be reached at 770-963-8017. The city doesn't spell out whether plumbing-only work uses the same process, so ask your plumber whether a disposal job needs a permit.
Before the plumber arrives, turn the disposal off and unplug it, clear the cabinet under the sink, and skip chemical drain cleaners. If you know whether your home is on Gwinnett sewer or a private system, mention it, along with how old the disposal is and whether the dishwasher drains through it. If you can see the label on the bottom, note the brand and model as well, since matching the mount can make a swap quicker.
Grayson note
With so many homes built in the same few years, disposals, dishwashers and faucets here tend to age together. When the plumber replaces one, ask about the dishwasher drain hose that connects to the disposal.
