In Triangle, a plumbing inspection is a plumber's walk-through of the water heater, supply and drain lines, fixtures, shutoffs and gas connections, with a sewer camera run if you want one. Most homes are newer, so original equipment is usually the main concern. Call the number on this page to be connected with a local plumber in Triangle.
Triangle conditions
Triangle sits in southeastern Prince William County between Dumfries, Prince William Forest Park and Marine Corps Base Quantico, and is home to the National Museum of the Marine Corps. Housing is mostly newer, with a median build year around 1999, so a plumber usually finds modern piping but builder-grade water heaters, regulators and valves that are 20-plus years old.
Prince William Water supplies Triangle with Occoquan Reservoir water treated at Fairfax Water's Griffith plant. Virginia American Water also runs a separate Prince William system, so the bill confirms the provider. Prince William Water uses chloramine most of the year with a spring switch to free chlorine, and describes its water as moderately hard. It states that the lines it owns and maintains are non-lead; customers are responsible for their own home plumbing.
Lines and connections on private property belong to the owner, and Prince William Water locates its lines only from the main through the meter box. A slow leak on the owner's side shows up on the bill, so the plumber will often watch the meter with every fixture off. Prince William Water also runs a cross-connection control program, so note any irrigation backflow device for the plumber.

Signs to schedule one

- Toilets that refill on their own
- A water bill that rose without explanation
- Rumbling or leaking from the water heater
Timing and permits
Book within the first days of the contract period so there's time to price repairs. Have outdoor spigots checked before freezing nights. Repairs are permitted by Prince William County Development Services; a gas tankless heater in an existing home needs a gas permit, plus a plumbing permit if water piping is extended more than 10 feet. If you smell gas, leave first, then call 911 and your gas utility. Prince William Water's emergency dispatch is 703-335-7990.
