Coats buys treated Cape Fear River water from Harnett Regional Water and sends it to about 970 town customers, so those homes don't own a pump. The 27521 ZIP reaches well past town limits, and rural homes there may be on Harnett Regional Water or a private well; on a well, lost water usually means the pump, switch or tank. Call the number on this page to be connected with a local plumber in Coats.

Am I on Coats water or a private well?
The Town of Coats Public Works runs about 29 miles of water lines and two elevated storage tanks, fed through metered connections from Harnett Regional Water. That serves roughly 970 residential, commercial and industrial accounts in town. The 27521 ZIP is much bigger, with about 6,500 people, and outlying addresses may be on Harnett Regional Water or on private wells. No one has published how many rural homes still pump their own water.
The easy check is your bill. A Town of Coats or Harnett Regional Water statement means public water. No statement, plus a pressure tank in a closet, crawl space or pump house, means a well.
Why does an older well system act up?
About 55% of homes in Coats were built before 1980, and the median home dates to 1978. Rural houses of that age often still have their original well setup or one that's been patched over the years. Common trouble spots on older systems include:
- Small steel pressure tanks without bladders, which lose air and waterlog
- Pressure switches with pitted contacts from decades of starts
- Galvanized drop pipe that corrodes and leaks inside the well
- Check valves that no longer seal, so water drains back between uses
Any of these can show up as weak pressure, rapid cycling or a pump that runs too long.
What should I do before calling?
If the pump is running nonstop, turn off its breaker. Check that the breaker hasn't tripped, and if it trips again after one reset, leave it off. Note the reading on the pressure gauge and whether there's water around the tank or soft ground between the well and the house. A plumber can use those details to narrow the problem down before arriving.
Some jobs, like pulling a deep submersible, may involve a well contractor. The plumber will tell you if that's the case.
Local note on permits
Harnett County Inspections provides building inspection services for Coats, including plumbing systems, but the county won't issue a building permit until the town grants a zoning permit. For rural 27521 homes outside town, Harnett County's Central Permitting office is the starting point.
