Inside city limits, Manassas homes are on the City of Manassas Water & Sewer system, which draws on Lake Manassas, so a private well pump is uncommon. Manassas mailing addresses also reach into Prince William County, where it depends on the address. For pump equipment or a pressure problem, call the number on this page to be connected with a local plumber in Manassas.

What happens when you call
The call connects you with an independent plumber who works in the Manassas area. Have a few answers ready: whether you pay the City for water, whether there is a pressure tank in the house, and when the trouble started. On public water, the plumber will check the regulator, main shutoff and fixtures. On a well or booster system, they test the power supply, pressure switch, tank charge and pump output.
Cost factors
- Replacing a switch, gauge or tank compared with pulling and replacing a pump
- How deep and how accessible the pump is on a real well
- Electrical repairs at the control or the circuit
- Leak repairs on the owner's line into the house
- Any permit required by the City's Development Services office
Local conditions in Manassas
The City runs its own water, sewer and electric utilities. Its water comes mainly from Lake Manassas, an impoundment on Broad Run, treated at the City's plant, with supplemental Potomac River water from Prince William Water during peak demand or emergencies. That makes Manassas different from its neighbors, and so does the hardness: the City reports about 47 ppm, softer than most of the region, so heavy scale in regulators is less of a factor here.
The median build year is 1985, with older homes around Old Town Manassas and newer areas toward the airport. Because the City also supplies electricity, a widespread power outage affects any booster or well pump at the same time as the lights. For water emergencies after hours, the City's line is 703-257-8353. Permits for city properties come from Development Services at City Hall.
Before the plumber arrives
- Check with a neighbor whether their water is normal
- Read the pressure tank gauge, if there is one
- Reset a tripped pump breaker once, and leave it off if it trips again
- Move stored items away from the tank, meter or well cap
- Note whether the problem started after a power flicker, a storm or nearby utility work
If your address is outside the city but carries a Manassas mailing name, your water may come from Prince William Water or another arrangement, and permits would go through Prince William County rather than City Hall. Your water bill settles which applies.
