Inside city limits, City of Manassas Water & Sewer runs the public sewer system, so the mains are the City's. The line from your house to that main is private plumbing, and a plumber repairs it when it fails. Call the number on this page to be connected with a local plumber in Manassas.

What happens when you call
You'll be connected with an independent plumber who works in Manassas. Expect a few questions first: which drains are affected, whether water has come up in a basement or tub, and whether this has happened before. On site, the plumber normally clears the blockage so the house can drain, then runs a camera from a cleanout to see what caused it. The camera picks out roots, cracked or offset joints, sags and debris, and a locator marks the spot and its depth. You'll get repair options once the problem is identified.
What affects cost
- How far the defect is from the house and how deep the line runs
- Whether the pipe can be lined or must be dug up and replaced
- Surfaces over the line: grass, walkways, a driveway or a patio
- Pipe material and how much of the run is damaged
- A building permit through City of Manassas Development Services
Manassas conditions
Manassas is an independent city about 27 miles from Washington, separate from Prince William County though it serves as the county seat. Its Old Town grew up around the railroad, and the median home today was built in 1985. Homes near the historic district are the most likely to have older clay or cast iron laterals; neighborhoods built later generally have plastic pipe that fails through settling, root entry at fittings or damage during later yard work.
The City runs its own water, sewer and electric utilities. Water & Sewer customer service is 703-257-8219 on weekdays, and the City's after-hours emergency number for its utilities is 703-257-8353. If sewage is coming from a manhole or the street, call the City. Permits for regulated work come from City of Manassas Development Services at City Hall, 703-257-8200. Manassas mailing addresses also spread into Prince William County outside city limits; those properties go to the County for permits, and your bill shows who provides sewer.
Quick checklist before the plumber arrives
- Stop running water and hold off on laundry and dishes
- Find the cleanout cap and clear access to it
- Keep children and pets away from backed-up drains
- Write down when the problem started and which fixtures were involved
