Local conditions in Triangle

Triangle sits in southeastern Prince William County, wedged between Dumfries, Prince William Forest Park and Marine Corps Base Quantico. Its housing is fairly new, with a median build year of 1999, so emergencies here tend to involve water heaters, supply hoses, valves and clogged drains rather than corroded old pipe.

Prince William Water names Triangle among the eastern county communities it supplies with Occoquan Reservoir water, treated at Fairfax Water's Griffith plant. Virginia American Water also runs a separate Prince William system nearby, so if you're unsure, your bill confirms it. Prince William Water's emergency dispatch line, 703-335-7990, takes main breaks and outages, and it also provides sewer service. The utility locates its lines from the main through the meter box; lines and connections on private property are the owner's responsibility.

Columbia Gas of Virginia and Washington Gas both operate in Prince William County, and your gas bill shows which one serves your home.

Seasonal notes

Cold snaps can split pipes in garages and exterior walls, and heavy summer rain can overwhelm yard drains and basements. Prince William Water uses chloramine most of the year and switches to free chlorine in spring, which can briefly change the taste of tap water; that's normal. Prince William County issues gas and plumbing permits if a repair becomes a replacement. Night and weekend calls usually cost more, and no arrival time is promised.

Emergency Plumber questions in Triangle

Water is gushing from the street or the meter box. Who handles that?

Call Prince William Water's emergency dispatch at 703-335-7990. The utility handles the main and the meter box; lines on private property are yours.

I smell gas near the furnace or water heater. What should I do?

Leave without touching switches. From outside, call 911 and the gas utility on your bill, either Columbia Gas of Virginia or Washington Gas. Propane homes call 911 and their supplier.

How do I find the main water shutoff and close it fast?

In most Triangle homes the main valve is where the supply line enters the house, often in a utility room, basement or garage. Turn it clockwise until it stops.

Does a night or weekend plumbing call cost more?

Usually, yes. Evening, weekend and holiday visits typically carry a higher service charge, so ask before the plumber is sent.
