Inside town limits, Haymarket homes get water and sewer from Prince William Water, so they have no well pump. The 20169 mailing area spreads into rural western Prince William County, where it depends on the address. If your home has a well, pressure tank or booster pump, or pressure has dropped, call the number on this page to be connected with a local plumber in Haymarket.

Do Haymarket homes have well pumps?
Inside the town, no: the Town lists Prince William Water for water and sewer. Prince William Water runs several systems, including one serving Bull Run Mountain and Evergreen customers from public groundwater wells; those wells belong to the utility, so homes on that system still have no pump of their own. Outside the town, in the rural parts of the 20169 area, a property may be on its own supply. Your bill is the quickest way to tell. If there is no water bill and the house has a pressure tank, it has a private well.
What usually goes wrong?
On public water, weak pressure is most often a regulator that has started to stick, a main valve that is not fully open or a leak on the owner's line. Haymarket's housing has a median build year of 1997, so many regulators are reaching that age. On a private well, the common failures are a pressure tank that has lost its air charge, a worn pressure switch, a bad check valve, damaged wiring or a pump at the end of its life. A plumber tests the above-ground parts first before pulling anything from the well.
Who issues permits and who do I call for outages?
Building permits and inspections come from Prince William County's Department of Development Services, after Town of Haymarket zoning approval for projects inside the town. For water outages or main breaks on Prince William Water, its emergency dispatch line is 703-335-7990, and customer service is 703-335-7950 on weekdays.
A local note
Haymarket's older core along Route 55 dates to the 1880s, surrounded by newer growth along I-66 and toward Bull Run Mountain Estates, Silver Lake Regional Park and James S. Long Regional Park. On rural properties, protect the pressure tank and any exposed piping from freezing nights, and remember that a well pump stops in a power outage. If you are on a well, ask the plumber about testing the water while they are there. Before the visit, read the pressure tank gauge, check the pump breaker once and clear a path to the tank and the well cap. In town, check with a neighbor first; if they are also short on water, the problem is likely on the utility's side.
