If your Bristow water heater has gone cold or started leaking, a few quick steps limit the damage, and a plumber can usually trace the problem to one part or a valve. A tank leaking from its body must be replaced. Call the number on this page to be connected with a local plumber in Bristow.
Bristow in brief
Bristow is mostly HOA-managed subdivisions built since 2000, and the median home in the Linton Hall area that includes it dates to 2004. That makes many heaters here original equipment that has now been running a long time, and newer homes are more likely than older ones to have power-vent gas units or tankless heaters, which carry more electronics than a basic tank. Water comes from Prince William Water, whose West System blends Potomac River water treated by Fairfax Water with Lake Manassas water treated by the City of Manassas. Its report lists ozone as the main disinfectant with chlorine added; hardness for your address is in that annual report.
Where a heater sits in a garage or an unfinished basement, location matters. Garage units are exposed to cold in winter, which makes the burner work harder, and basement units are often next to finished space where a leak spreads quickly. Either way, knowing where your shutoff valve is before something goes wrong saves a lot of mopping.
What to do now
- Smell gas? Leave the house, then call 911 and your gas utility from outside. Both Columbia Gas of Virginia and Washington Gas operate in Prince William County; your bill shows which serves you.
- Stop a leak. Close the cold-water valve feeding the heater.
- Shut off energy. Turn off the breaker for an electric unit, or set the gas control to off.
- Look for a code. Many newer units flash a status light or show an error code. Write it down.
- Protect the area. Move boxes and put towels down.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Power-vent unit will not start | Blower motor, pressure switch or blocked vent |
| Tankless shows an error and shuts down | Ignition fault, flow sensor or scale |
| Hot water runs short | Sediment, dip tube or a failed element |
| Relief valve dripping | High pressure, overheating or a worn valve |
| Water on the floor | Fitting, drain valve or a failed tank |
Cost factors
- Electronic parts on power-vent and tankless units versus simple tank parts
- Whether the unit needs flushing or descaling
- Garage, attic or basement location
- Whether the venting has to be cleared or a condensate line repaired
- Permits if the job grows: Prince William County requires a gas permit for gas piping and venting, plus a plumbing permit if water piping is extended more than 10 feet
