Triangle's housing is mostly newer, with a median build year of 1999, and the original water heaters in many homes are now old enough to leak or fall short, which makes replacement the usual fix. Prince William County Development Services handles gas, plumbing and electrical permits for Triangle. Call the number on this page to be connected with a local plumber in Triangle.

Triangle conditions to know
Triangle sits in southeastern Prince William County between Dumfries, Prince William Forest Park and Marine Corps Base Quantico. Prince William Water supplies the area with Occoquan Reservoir water treated at Fairfax Water's Griffith plant. The utility describes its water as moderately hard, which it defines as 61 to 120 mg/L, so sediment does settle in a tank over the years. It uses chloramine most of the year and switches to free chlorine in spring, which can briefly change taste and smell at every tap. Virginia American Water also runs a separate Prince William system, so your bill confirms the provider.
Both Columbia Gas of Virginia and Washington Gas operate in Prince William County, so check your gas bill to see which serves your home. If you smell gas, leave the house first, then call 911 and that utility from outside. All-electric homes skip that concern but may need circuit work for a larger or heat pump heater.
Replacement options compared
| Option | Best when | What to weigh |
|---|---|---|
| Matching tank | The current heater met demand | Simplest swap with existing lines and vent |
| Larger tank | The household has grown | Space, venting and fuel supply |
| Gas tankless | Steady demand and limited space | County gas permit; plumbing permit if water piping is extended over 10 feet or changes material |
| Heat pump electric | All-electric homes with room for airflow | Higher upfront cost; needs open space |
Signs it's time
- A leak from the tank itself
- Discolored or odd-smelling hot water
- Popping or rumbling as it heats
- Hot water that runs out sooner than it used to
Seasonal and timing notes
Winter pushes a heater hardest, as colder incoming water means longer heating cycles, so a tank that was struggling in fall often fails in January or February. If your heater is original to a late-1990s or early-2000s home, pricing a replacement ahead of the cold months leaves room to compare a straight match against an upgrade. In spring, if the water smells more of chlorine, that's Prince William Water's seasonal switch rather than a sign your heater is failing.
Households change over the years, so it's worth sizing the new heater for how the home is used now rather than simply copying the old label.
