Most Cumming homes date from the 1990s and later, so a dripping or temperamental shower usually has a worn cartridge in a single-lever valve. A plumber can replace it through the trim. Inside city limits, the City of Cumming issues plumbing permits. Call the number on this page to be connected with a local plumber in Cumming.
What's usually wrong with a Cumming shower valve?
Census survey figures put Cumming's median year built at 1998, with about 17% of homes from before 1980. Most showers have pressure-balancing single-lever valves from major brands. After 20 to 25 years, cartridges and seals wear, causing drips, stiff handles or temperature jumps. A new cartridge usually fixes it.
Who supplies water in and around Cumming?
Cumming Utilities, run by the City of Cumming, pumps Lake Lanier water to its own treatment plant and also runs sewer. Its 2026 report lists chlorine disinfection, added fluoride and no lead service line material found in its system to date.
Cumming is the Forsyth County seat, and some nearby addresses are served by Forsyth County instead. The city's service area map shows which is which, so check your water bill.
Does the city require a permit?
Inside city limits, the City of Cumming Planning and Zoning office handles building permits and inspections, including plumbing permits, using a downloadable application. Inspections are requested by phone. A cartridge swap is usually repair work; ask the plumber whether a full valve replacement needs one. Addresses outside city limits go to Forsyth County.
On a typical visit, the plumber shuts off the water, removes the trim and pulls the cartridge. Common brands are usually on hand. If the valve body is cracked or leaking inside the wall, the plumber looks for access from behind the shower before cutting into tile. Larger homes with multi-head showers have more parts that can wear, so describing the setup on the call helps the plumber come prepared. If you're not sure whether your home is on Cumming Utilities or Forsyth County water, the bill will say. It doesn't change the valve repair, but it matters if the plumber finds a leak at the meter. Cumming's report also notes fluoride is added, which has no effect on shower valve parts.
A local note
Cumming grew from a small rural town into a GA-400 commuter suburb, and many homes went up in the same years. Their shower valves are aging together, so if one bathroom's valve has started to drip, the others may not be far behind.
