Inside city limits, the City of Manassas runs its own water and sewer utility, so the public mains are a City matter while the lines on your property are yours. A plumber can clear the clog and tell you where it was. Call the number on this page to be connected with a local plumber in Manassas.

How the call works
When you call, you are connected with an independent plumber who serves Manassas. A few quick questions come first: which drains are slow, whether sewage reached the floor, and whether the house has a basement. On site, the plumber runs fixtures to see how the system behaves, locates the nearest cleanout and picks a tool. A sink or tub clog is usually cleared at the fixture. A main line blockage is usually cleared through a cleanout in the basement or yard. If clogs keep coming back, a camera inspection can show why.
What the price depends on
- Whether one fixture or the whole house is affected
- How easy it is to reach and open the cleanout
- Cabling only, or jetting and camera work as well
- What turns up, such as roots, a sag or a cracked joint
- Day and hour of the visit
Ask for the price before work starts and what could change it.
Local conditions in Manassas
Manassas is an independent city and the Prince William County seat, with a historic Old Town and neighborhoods built over many decades; the median home dates to 1985. Houses in and around Old Town are where older cast iron and clay lines are most likely, while newer neighborhoods tend to clog from grease, wipes and hair.
The City of Manassas Water and Sewer utility serves addresses inside city limits, and its after-hours emergency line, 703-257-8353, covers City water and sewer problems. Manassas mailing addresses also reach into Prince William County, where service is different, so check your bill. City water comes mainly from Lake Manassas and is relatively soft, about 47 ppm total hardness, so mineral scale plays a smaller part in drain buildup here than in neighboring systems.
Checklist before the plumber arrives
- Stop using water if more than one drain is backing up
- Call the City's after-hours line if sewage is coming from a manhole
- Find the cleanout, often a capped pipe near the foundation or in the basement
- Clear a path to the affected fixtures
- Skip chemical drain openers
Clearing a clog is service work. Pipe replacement inside city limits goes through City of Manassas Development Services; addresses outside the city go to Prince William County.
