Broad Run sits at the foot of Thoroughfare Gap in the Bull Run Mountains, the easternmost mountains in Virginia, and its ZIP spills over the county line. The Census puts 571 of its 690 homes in Fauquier and 119 in Prince William. Neither county’s water reaches the village. Broad Run isn’t one of Fauquier’s service districts, and on Prince William’s map not one of the 178 Broad Run single-family addresses is within 200 feet of a Prince William Water line. Only at the south edge of the ZIP, north of Lee Highway, does FCWSA’s New Baltimore district reach in.
So for almost everyone here, the well is the water. The houses in the rural historic district sit on the high ground of each property, with the fields, woods and spring-fed hollows below, which often means a long run of buried pipe from the well head up to the house and a pressure tank at the end of it. A leak or a crushed line on that run looks a lot like a tired pump, and we rule it out before we pull anything.
This is an older housing stock than most of the area. Every owner home in the ZIP is a detached house, the median was built in 1979, and more than half went up before 1980. A well drilled for a 1970s house has been working for decades, and the wire and drop pipe from that era are often as tired as the motor. That’s why we test the wire from the house: a pump alone on sound wire is $2,781 to $4,000, and with new wire and pipe it’s $4,900 to $6,500.
The rock under the village is Harpers phyllite, a layered, slatey stone. Fauquier’s household water clinics found low pH in close to half the wells they tested, and acidic water eats at brass and copper once it’s inside. On a well that’s been running thirty years, pinhole leaks at the tank tee or a corroded pressure switch fitting are worth checking while we’re there.
