Bristow is unincorporated Prince William County, so Prince William Water handles water and sewer and the county's Building Development Division issues plumbing and gas permits. Gas varies by address because both Columbia Gas of Virginia and Washington Gas operate in the county. Plumber Washington DC Pros is a free referral line, not a plumbing company; call the number on this page to be connected with a local plumber in Bristow.

Plumbing services in Bristow
Subdivisions between Manassas and Gainesville
Bristow is an unincorporated community inside the Linton Hall census-designated place, which counted 41,754 residents in 2020. It sits about 31 miles from downtown Washington between Manassas and Gainesville, and it is mostly HOA-managed subdivisions such as Braemar, Victory Lakes and Kingsbrooke, built largely since 2000. Linton Hall Road, Nokesville Road (Route 28) and Bristow Road carry traffic, and Manassas Regional Airport and the Broad Run VRE station are next door.
New houses, typical first-generation repairs
The median home in the Linton Hall CDP was built in 2004. That makes Bristow a place for first-generation repairs rather than old-pipe replacement: builder-grade water heaters reaching the end of their service life, tankless conversions, PEX fittings and manifold leaks, toilet and faucet valve wear, sump pumps in finished basements and kitchen drain clogs. Frozen hose bibs and pipes in garages and bonus-room walls still show up in cold snaps.
Water and sewer from Prince William Water
Prince William Water runs several distribution systems, and western-county customers are on its West System, which blends Potomac River water treated by Fairfax Water at the Corbalis plant with Lake Manassas water treated by the City of Manassas. The utility uses ozone as the primary disinfectant for surface water, with chlorine added as a secondary disinfectant. For hardness at your address, check Prince William Water's annual water quality report. The utility says every distribution line and service line it owns is non-lead and publishes a service line inventory. Emergency dispatch for main breaks and outages is (703) 335-7990; customer service is (703) 335-7950.
Prince William Water also provides sewer service, with wastewater treated at the Upper Occoquan Service Authority plant and the H.L. Mooney Advanced Water Reclamation Facility. It runs a cross-connection control program for backflow devices, so homes with irrigation should keep their test paperwork current.
Permits for water heater changes
Prince William County's Department of Development Services, Building Development Division (5 County Complex Court, 703-792-6930), issues plumbing, gas and electrical permits. Converting a tank water heater to a gas tankless unit needs a gas permit for the piping and venting, plus a plumbing permit when water piping is extended more than 10 feet or the pipe material changes, and an electrical permit if a new circuit is required.
Gas: check your bill
Both Columbia Gas of Virginia and Washington Gas run distribution systems in Prince William County, so the utility on your bill is the one to call. If you smell gas, leave the house first, then call 911 and your gas utility's emergency number from outside.
Bristow compared with the District
DC's housing is much older and its utilities are DC Water and Washington Gas. Bristow homes are among the newest in the region, with Prince William Water and county permits. Call with your subdivision and the issue, and you will be connected with an independent plumber who sets price and timing with you.
