Inside the City of Manassas, City of Manassas Water & Sewer supplies water treated from Lake Manassas. When the buried line on your property leaks or breaks, a plumber can locate the damage and repair or replace the line. Call the number on this page to be connected with a local plumber in Manassas.

What happens when you call
Plumber Washington DC Pros is a referral service, not a plumbing company. Your call is connected with an independent local plumber who works in Manassas. You'll be asked where the water is showing up, whether pressure has dropped and whether you're inside city limits or in a Manassas-addressed part of Prince William County. The plumber will then find the leak, explain what failed and walk you through the choice between repairing a section and running a new line.
Cost factors
- Distance and depth. Longer and deeper runs take more digging and pipe.
- The failure itself. A cracked fitting is a smaller job than a corroded line.
- Surface work. Sidewalk edges, driveways and landscaping add restoration time.
- Where the line enters. A finished basement or slab entry takes more care.
- Permits. City of Manassas Development Services issues building permits for work regulated by the state building code; Manassas-addressed homes outside city limits go to Prince William County.
Manassas conditions
Manassas is an independent city, separate from Prince William County, and it runs its own water, sewer and electric utilities. Its water comes mainly from Lake Manassas on Broad Run, treated at the City's plant, with supplemental water from Prince William Water during peak demand. The City's water is relatively soft, about 47 ppm total hardness, so scale inside the service line is not usually what causes trouble here. Worn fittings, older pipe, shifting soil and accidental damage are more likely.
The median home was built in 1985, with older houses around Old Town and the historic district. The City has completed a service line material inventory and published it online, and Water & Sewer keeps a Lead Pipes page; checking your address there is a good first step on an older house. For a leak at the meter or in the street, call the City's after-hours emergency line, 703-257-8353, or Water & Sewer customer service at 703-257-8219 on weekdays, and ask where the City's responsibility ends at your property.
