In the Town of Dumfries, a hidden leak usually shows up as a higher Prince William Water bill, a meter that keeps moving, or a stain that won't stop spreading. A plumber can test the system in sections to find the source. Call the number on this page to be connected with a local plumber in Dumfries.

When you call
The number on this page connects you with an independent plumber who serves Dumfries. Expect questions about your bill, your meter and any damp areas. The plumber will confirm the leak at the meter, shut the house valve to see whether it's in the yard or indoors, then divide the indoor plumbing into hot and cold and use acoustic, thermal or moisture tools to find the exact spot. Walls and floors are opened only where the readings point. If the leak turns out to be on the utility's side of the meter, the plumber will tell you so, and Prince William Water takes it from there.
What affects the cost
- The time it takes to isolate the leak
- How hard the pipe is to reach
- The detection gear needed
- Repair size, and whether a Town permit and inspection are involved
Dumfries specifics
Chartered in 1749, Dumfries is often described as the oldest continuously chartered town in Virginia, and it has its own building and inspection department. Plumbing permits and inspections inside town limits, including domestic water service, go through the Town of Dumfries Building and Inspection Department at Town Hall, 17739 Main Street, (703) 221-3400, not Prince William County.
Water comes from Prince William Water, which supplies the town with Occoquan Reservoir water treated at Fairfax Water's Griffith plant; the utility's Route 1 water main work refers to a Dumfries pressure zone. It rates the water moderately hard, 61 to 120 mg/L. For billing and usage, customer service is (703) 335-7950 on weekdays. Main breaks and outages go to emergency dispatch at (703) 335-7990, and water quality questions to 703-331-4162.
Dumfries has a long history, but the age of individual houses varies widely, so ask the plumber about the age and material of your supply lines while they're on site. That helps decide whether a found leak is a one-time repair or a sign that more of the line is due.
Checklist before the plumber arrives
- Find the meter box and the main shutoff
