Many Great Falls homes rely on private wells, while some neighborhoods are served by Fairfax Water, so the line feeding your house runs either from a meter or from your own well. Either way, a buried line that leaks or breaks is a plumbing repair. Call the number on this page to be connected with a local plumber in Great Falls.

When you call
Plumber Washington DC Pros is a referral service, not a plumbing company, so your call goes to an independent local plumber who works in Great Falls. Start by telling them whether your water comes from a well or Fairfax Water, because that changes the job. On a well, the plumber looks at the line from the wellhead to the pressure tank and into the house, and may check whether the pump is running constantly to keep up with a leak. On public water, the work starts at the meter and follows the line to the main shutoff.
What shapes the cost
- Distance. Large lots mean long runs from the street or the well.
- Terrain. Wooded, rocky or sloped ground slows digging.
- Repair scope. One fitting versus a full new line.
- Well components. A leak may also stress the pump, pressure switch or tank.
- Restoration. Long driveways, stone walls and landscaping over the line.
Great Falls conditions
Great Falls is an unincorporated, partly rural community on the Potomac River, about 16 miles from Washington, known for large lots and nearby Great Falls Park. The local citizens association notes that many homes rely on private wells and that some neighborhoods are served by Fairfax Water. Many homes are also not on public sewer and use private onsite wastewater systems, so the plumber will want to know where that system sits before digging near it. The median home was built in 1985.
For Fairfax Water customers, the utility owns the meter and its setting, and the homeowner owns all pipes on the property, including the line from the meter to the house. A leak at the meter goes to Fairfax Water at 703-698-5800. For well homes, everything from the well to the faucets is the owner's. Fairfax County Land Development Services issues residential plumbing permits through PLUS.
