In the City of Manassas, most toilet problems are a worn flapper or fill valve, a failed wax seal or a clog in the bowl. City water is relatively soft, so worn rubber is a more common culprit than scale. Call the number on this page to be connected with a local plumber in Manassas.

Here is how the call works
When you dial the number on this page, you are connected with an independent plumber who serves Manassas. Expect a few quick questions: is the toilet running, leaking, clogged or loose, is water on the floor, and is the bathroom upstairs, on the main level or in the basement. Share whether other drains are slow. With that, the plumber can tell you what the repair probably involves and set a time.
What affects the cost
- Type of repair: tank parts are a shorter job than pulling and resetting the toilet.
- Floor and flange: damaged subfloor or a broken flange adds time and parts.
- Valve and line: an old shutoff that won't close is usually replaced.
- Clog location: a blockage past the toilet takes more equipment.
- Repair or replace: a new toilet adds the fixture and haul-away.
- After hours: nights and weekends generally cost more.
Local conditions in Manassas
Manassas is an independent city with its own water, sewer and electric utilities. Its water comes mainly from Lake Manassas on Broad Run, treated at the City's plant and disinfected with chlorine, with supplemental Potomac River water from Prince William Water at peak times. The City's report lists total hardness of 47 ppm, softer than most of the region. Scale is less of a factor here, so a running toilet usually traces back to a flapper that has warped or a fill valve that has worn out rather than to mineral crust.
The typical home in the city was built in 1985, and Old Town Manassas holds older houses. Many toilets are on their second or third replacement, sometimes on a flange that has been reused each time.
For a utility emergency after hours, the City's line is 703-257-8353; customer service for Water and Sewer is 703-257-8219 on weekdays. Manassas mailing addresses also reach into Prince William County, where a different utility and the County's permit office apply. Inside the city, City of Manassas Development Services handles building permits.
Checklist before the plumber arrives
- Turn off the valve behind the toilet, or the house main if it sticks
- Don't flush again if the bowl is full
- Mop up and set towels where water keeps appearing
- Note whether the sink, tub or washer drain is also slow
- Have the City utility bill handy if you suspect a leak
