Water Heater Repair in Great Falls, VA

What happens when you call

You are connected with an independent plumber who works in Great Falls. Mention whether your home is on a private well or public water, whether the heater is gas or electric, and roughly how old it is. On the visit, the plumber checks the energy supply, the controls and elements or burner, the relief valve, the drain valve and the connections, and drains a little water to see how much sediment is in the tank. Well homes often show more grit, which changes the advice on flushing.

What affects the cost

• The part involved. An element or thermocouple is simpler than a gas valve or control board.
• Sediment. Tanks on well water can need a longer flush.
• Size and setup. Large homes may have two heaters or a recirculation pump.
• Water treatment. Filters or softeners ahead of the heater may need attention too.
• Timing. Nights and weekends cost more.

Local conditions in Great Falls

Great Falls is partly rural, with large lots near the Potomac, and its utilities reflect that. The Great Falls Citizens Association notes that many homes rely on private wells, while some neighborhoods are on Fairfax Water, and many homes are not on public sewer and use a private onsite wastewater system instead. Well water can carry sand, sediment, iron or other minerals that end up in the bottom of a water heater, and the association recommends testing well water every year, or sooner if smell, taste or appearance changes. A sudden rotten-egg smell from hot taps only is usually a tank issue, but a change in the cold water too points to the well.

For homes on Fairfax Water, tests at its Potomac plant show total hardness of about 70 to 185 mg/L, moderately hard. The median home in Great Falls was built in 1985. Washington Gas runs pipelines throughout the area, though not every house is connected, so some heaters are 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.
