Haymarket's median home dates to 1997, so most houses have newer copper or PEX supply lines, while the small historic core holds much older homes where original pipe is more likely. A repipe makes sense when leaks keep returning in the same generation of pipe. Call the number on this page to be connected with a local plumber in Haymarket.

Does a Haymarket house this new really need a repipe?
Often it doesn't need a full one. Haymarket is a small historic crossroads town at the base of the Bull Run Mountains, with a largely unchanged 1880s core surrounded by newer growth along I-66. In the newer homes, problems usually trace to a fitting type that keeps failing, a run that froze in a garage ceiling or outside wall, or damage from a remodel, and a targeted or partial repipe is usually enough. In the older homes near the town center, original steel or early copper is more likely, and a whole-house repipe is a more common recommendation.
Who supplies the water, and what's mine?
The Town lists Prince William Water for water and sewer within town limits. Prince William Water says that all of the distribution systems and service lines it owns and maintains are non-lead, and that customers remain responsible for their home plumbing. Most of its water is treated at Fairfax Water facilities, while some western county customers receive water treated at the City of Manassas plant from Lake Manassas. The Haymarket 20169 postal area also covers large unincorporated areas outside town, where service varies by address, so check your bill before work is scoped.
How do permits work in Haymarket?
All building permits in town, including plumbing, are issued by Prince William County Development Services, but applicants first get Zoning Approval from the Town of Haymarket. The plumber usually handles the County side; make sure the Town step is part of the plan. Homes with Haymarket addresses outside town limits go straight to the County.
A local note
Before the work starts, ask the plumber to walk through the route the new lines will take and which walls, closets or ceilings will be opened. In newer homes with finished basements, careful routing through utility rooms and closets can keep patching to a minimum.
Haymarket is on Columbia Gas of Virginia rather than Washington Gas, which matters if gas lines near the water heater are part of the work. Any gas piping changes need their own permit and should be handled carefully. If you ever smell gas, leave the house first, then call 911 and Columbia Gas of Virginia at 1-800-544-5606 from outside.
