A Great Falls slab leak is a pipe leaking inside or under a concrete floor, usually a basement slab, a garage or an addition. Many Great Falls homes rely on private wells while some neighborhoods are on Fairfax Water, and either way the plumbing on the property is the owner's. Call the number on this page to be connected with a local plumber in Great Falls.
What happens when you call
The call connects you with an independent plumber who serves Great Falls. Tell them first whether the home is on a private well or on Fairfax Water, because that changes how the leak is confirmed. On public water, the plumber starts with the meter. On a well there is no meter, so the clues are a pump that cycles or a pressure tank that refills when nobody is using water, along with any dampness or warmth on the floor. Pressure testing and acoustic or thermal locating then pinpoint the leak.
Cost factors
- Detection, especially on well systems where the leak has to be isolated without a meter
- A direct repair through the slab versus rerouting through walls or ceilings
- Stone, tile or radiant flooring over the leak
- Water damage to finished basement spaces
- Fairfax County Land Development Services permits through PLUS when the repair calls for one
Great Falls conditions
Great Falls is a mostly residential community along the Potomac with large lots and a partly rural character, and its median home was built around 1985. Many houses are big, with finished basements, additions and stone floors, which makes reaching a buried pipe more involved than in a typical suburb.
Water service varies by address. The local citizens association notes that many homes rely on private wells and that some neighborhoods are served by Fairfax Water. On a well, a hidden leak forces the pump to run more often, which wears the pump and pressure switch as well as damaging the floor. On Fairfax Water, the utility owns the meter, and the homeowner owns everything after it, including the line to the house. Many homes are also not on public sewer and use private onsite wastewater systems, so the drains under a slab lead to that onsite system rather than a county main, and a plumber traces a drain leak on the house side of it.
Checklist
- Confirm whether the house is on a well or Fairfax Water
- On a well, listen for the pump starting when no water is in use
- On public water, run the meter test and record the readings
- Find the main shutoff, which on a well is usually near the pressure tank
- Photograph damage and clear access to the basement and mechanical room
