Plumber in Nolensville, TN

What does Nolensville's hard water do to a water heater?

The town lists the Nolensville/College Grove Utility District as its water utility. The district buys its water from three suppliers. Its latest water quality report names the Town of Smyrna, Metro Nashville and the Mallory Valley Utility District. Hardness comes from natural calcium and magnesium in that water, the district says.

Hard water leaves spots on dishes and scale in pipes and water heaters. To help, the district suggests setting a water heater at 130 degrees or below. White specks in the water are another clue. In vinegar, calcium specks fizz, while bits of a worn water heater dip tube float.

When scale settles in the bottom of a tank, a flush clears it out. We do that as part of water heater repair. A tank that leaks from its body has rusted through, and a new water heater is the fix.

Irrigation, backflow and the May test in Nolensville

Irrigation drives the district's peak water demand, its own letter on watering days says. Under its address-based schedule, odd-numbered addresses may irrigate on Monday, Wednesday and Friday. Even-numbered addresses get Tuesday, Thursday and Saturday. The schedule covers automatic systems, and hand watering falls outside it.

Every irrigation system on district water needs backflow protection, and so do drip and misting systems. The district's rule calls for a reduced pressure backflow assembly at the meter or just past it. Its relief port must sit at least 12 inches, plus the port's size, above the ground or mulch.

The district tests each device every year, starting May 1, through a contracted tester. You get a call at least 24 hours ahead, and the water must be on to the device's second shutoff. A device that fails must be repaired within 30 days of the notice. We handle backflow preventer repair and replacement when that notice comes.

Old Nolensville Road, new subdivisions and town code

Nolensville has grown fast. When the town re-incorporated in 1996, it covered about three square miles and around 1,800 people. The 2020 Census counted 13,829 residents, more than double the 5,861 of 2010. A town special census in late 2023 raised the official count to 16,836.

The old town center sits along Nolensville Road. From north of Oldham Drive to York and Williams Roads, many 1800s buildings still serve as homes and stores. Subdivisions such as Bent Creek and Winterset Woods came with the growth.

The town enforces the 2024 International Plumbing Code. Its local amendments call for fire sprinklers in new houses, with a 1-inch water meter and service line. The town sets the freeze depth for piping in trenches at 12 inches. Crawl spaces need a positive drain.

Mill Creek runs through town, and it has flooded before. The town's history records a Mill Creek flood in 1979. In 1984, floodwaters closed Nolensville Road. Where water collects under a house, a sump pump is one fix.

Who handles sewer and gas in Nolensville?

Sewer is not the water district's job: Metro Nashville serves the Nolensville area, on its own bill. Some addresses in the district use City of Brentwood sewer, and the district office can say which serves yours. A clogged drain or a broken sewer line at the house is plumbing work we handle.

For gas, the town's utility list names Atmos Energy. The same Census survey shows about seven in ten homes here heat with utility gas. The town has also adopted the 2024 International Fuel Gas Code. Adding a gas range or an outdoor grill takes gas line installation, and we do that work.
