A Haymarket plumbing inspection is a plumber's check of the water heater, supply and drain piping, fixtures, shutoffs and gas connections, with a sewer camera run if you want one. Gas here is Columbia Gas, and permits involve both the Town and Prince William County. Call the number on this page to be connected with a local plumber in Haymarket.

What will a plumber focus on in a Haymarket house?
Haymarket is a small historic crossroads town at the base of the Bull Run Mountains, with an 1880s core surrounded by newer growth along I-66. The median home was built around 1997, so in most houses the piping is modern and the attention goes to equipment: water heaters, pressure regulators, sump pumps, washing machine hoses and shower valves that came with the house. In the older homes near the center of town, drain lines and valves get a closer look.
Who supplies water and sewer, and what about the wider 20169 area?
The Town lists Prince William Water for water and sewer within town limits. Prince William Water's West System blends Potomac River water treated at Fairfax Water's Corbalis plant with Lake Manassas water treated by the City of Manassas, and its Bull Run Mountain and Evergreen systems run on public groundwater wells. The 20169 mailing area also covers large unincorporated stretches outside town, and service there varies by address, so check the bill or ask the seller. Prince William Water says all the lines it owns are non-lead; the pipe on your side is yours, and a plumber can identify it.
Which offices handle gas and permits?
Gas in Haymarket is Columbia Gas of Virginia, not Washington Gas. If you smell gas, get outside, call 911, then Columbia Gas at 1-800-544-5606. Building and trade permits in town, including plumbing, are issued by Prince William County Development Services, but only after Zoning Approval from the Town; Town Hall is at 703-753-2600. A plumber can tell you which findings will need a permit so you can factor in the extra step.
Prince William Water also runs a cross-connection control program, so let the plumber know about any irrigation system and its backflow device.
A local note
Book early in the inspection period, especially if a camera run or a gas appliance check is part of the visit. Ask for the findings in writing, with urgent items such as an active leak or a gas connector problem listed apart from things to budget for, like an aging water heater. That makes the conversation with a seller simpler. For a water main break or outage, Prince William Water's emergency dispatch is 703-335-7990, any time of day.
