A Triangle water heater that runs cold or leaks usually needs a single part, a valve or a flush, and a plumber can generally tell on the first visit whether it is worth repairing. A tank that leaks from its body must be replaced. Call the number on this page to be connected with a local plumber in Triangle.

Local conditions in Triangle
Triangle sits in southeastern Prince William County between Dumfries, Prince William Forest Park and Marine Corps Base Quantico, and its housing is mostly newer, with a median year built of 1999. Many heaters here are original to houses that are now more than two decades old, or are first replacements, and they are reaching the age when anode rods, igniters, elements and gas valves start to give out.
Prince William Water names Triangle among the eastern county communities it supplies from the Occoquan Reservoir, treated at Fairfax Water's Griffith plant. Its report lists ozone as the primary disinfectant with chlorine added, and the utility says it uses chloramine most of the year and switches to free chlorine in the spring. Prince William Water describes its East and West systems as moderately hard (61 to 120 mg/L), so scale builds slowly but still collects in a tank that is never drained. Virginia American Water also runs a separate Prince William system in the county, so check your bill if you are unsure which utility serves you.
Both Columbia Gas of Virginia and Washington Gas operate in Prince William County, so the name on your gas bill tells you who to call. If you smell gas, leave the house first, then call 911 and your gas utility from outside. Prince William County Development Services issues the permits here.
Repair or replace
| Problem | Usually | Why |
|---|---|---|
| No heat on a dry, mid-age tank | Repair | Elements, thermostats and igniters are routine |
| Leak at the drain valve or a fitting | Repair | The tank itself is intact |
| Sulfur smell from hot taps | Flush and check anode | Usually an anode reaction |
| Water from the tank shell | Replace | The tank has failed |
| Converting to tankless | New install | Needs a county gas permit and possibly a plumbing permit |
Signs to watch for
- Hot water running out sooner than it used to
- Popping or crackling during heating
- Moisture under the heater
- A burner that will not stay lit
Timing notes
Households tied to nearby Marine Corps Base Quantico may move on a set schedule, so it is worth having a heater checked before a move-out inspection or soon after moving in, when you do not yet know the unit's history. Winter is when weak heaters fail, so a fall check is a sensible habit.
