Fairfax Station conditions

Fairfax Station began in 1851 as a stop on the Orange and Alexandria Railroad and is now a mostly residential, car-dependent community of larger lots in southern Fairfax County. The median home dates to 1982, so most houses have replaced their original water heater, and larger homes may run an oversized tank, two heaters or a recirculation pump. Each adds parts that can fail, so it helps to know which heater serves which part of the house before the plumber arrives.

Fairfax County lists Fairfax Water as the water provider for county residents, supplied from the Occoquan Reservoir and the Potomac River. Fairfax Water's tests show total hardness of roughly 70 to 185 mg/L at its Potomac plant and about 77 to 147 mg/L at its Occoquan plant, both moderately hard, so tanks here collect sediment over the years. Fairfax Water owns the meter, and the line from the meter to the house is the homeowner's. If your property has its own well, mention it on the call, since well water changes the maintenance advice.

Washington Gas serves most of the county, though gas may not reach every street; some homes are all-electric. If you smell gas, leave the house first, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1. Fairfax County Land Development Services requires a permit for gas water heater replacement even when like-for-like, but many part repairs are smaller jobs.

Water Heater Repair questions in Fairfax Station

Does my water heater need an expansion tank?

Homes with a pressure reducing valve or check valve on the main often need an expansion tank so heated water has room to expand. A dripping relief valve is a common clue.

Does water heater work here need a permit?

Fairfax County requires a permit for gas water heater replacement, even like-for-like, through Land Development Services. Many part repairs do not need one; the plumber can confirm.

Why does my hot water run out faster in winter?

Colder incoming water means every gallon needs more heat, so a tank delivers less hot water in January than in July. A worn element or sediment makes the gap wider.

How often should the tank be drained and flushed?

Once a year is a reasonable starting point with moderately hard water. Large tanks and homes with heavy use may benefit from more frequent draining.
