Prince William Water provides public water and sewer service in eastern Prince William County, including Triangle, and lines and connections on private property belong to the owner. A sewer camera inspection films the drain line from your house to the public sewer to find what is causing backups. Call the number on this page to be connected with a local plumber in Triangle.

Local conditions in Triangle
Triangle is a southeastern Prince William County community wedged between Dumfries, Prince William Forest Park and Marine Corps Base Quantico, and home to the National Museum of the Marine Corps. Housing is mostly newer, with a median year built of 1999, so most laterals are plastic. On camera, plastic lines of that age tend to show bellies where trench backfill settled, joints that shifted, roots slipping into a loose fitting near wooded edges, or damage from later fence and patio work. Older homes in the area may still have earlier pipe materials.
Prince William Water owns the meter and the public system, and the owner is responsible for lines and connections on private property. The utility's Emergency Dispatch at 703-335-7990 handles main breaks and outages, and it also takes requests about sewer cleanout cap replacement. Customer service is 703-335-7950. Virginia American Water runs a separate system elsewhere in the county, so if you are unsure who serves you, check your bill.
Inspection approaches compared
| Approach | When it fits | Trade-off |
|---|---|---|
| Camera from the outside cleanout | Most homes with an accessible cleanout | A full line must be cleared first |
| Camera through a toilet | No usable cleanout | Toilet is pulled and reset |
| Jetting, then camera | Grease or wipes coating the pipe | More time, clearer picture |
| Follow-up camera after a repair | Checking a new section or liner | A second visit, but a solid record |
Signs to look for
- Slow drains in more than one room
- Toilets gurgling while the washer drains
- Water backing up into a tub or floor drain on the lowest level
- A sewer odor near the cleanout outside
- Clogs that come back after cleaning
Timing notes
Heavy summer storms can push groundwater into a cracked or separated joint and overload a weak line, so a backup right after a downpour is worth a camera look. If sewage is coming up, stop using water and get help promptly. If drains are only slow, a planned inspection is easier than an emergency visit. Repairs that replace pipe need a permit from Prince William County's Building Development Division. When you call, you are connected with an independent plumber who works in Triangle.
