Commercial Plumbing in Triangle, VA

Triangle's utilities and rules

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 check the bill if you're unsure. The utility uses ozone at the plant and chloramine in the pipes most of the year, switching to free chlorine in spring, which can briefly change taste and odor. It classifies its water as moderately hard (61 to 120 mg/L), so commercial water heaters and kitchen equipment need periodic descaling.

Prince William Water locates lines from the main through the water meter box; lines and connections on private property are the owner's. Prince William Water also provides sewer service, though it's worth confirming for a specific address. Its cross-connection program calls for testable backflow devices to be tested by a certified company at installation or repair and every year after, with results sent to the Cross Connection Coordinator. Emergency Dispatch is (703) 335-7990 and Customer Service is (703) 335-7950.

Permits come from the Prince William County Building Development Division (703-792-6930). A gas tankless water heater in an existing building needs a gas permit, plus a plumbing permit if water piping is extended more than 10 feet or the material changes. Both Columbia Gas of Virginia and Washington Gas operate in the county; check the bill, and if anyone smells gas, leave and call 911 and that utility from outside.

Timing notes

Housing here is mostly newer, with a median home built in 1999, so many buildings are reaching the age when original heaters and valves give out. Plan replacements before the busiest visitor seasons and winterize outdoor lines before hard freezes.
