Water Heater Repair in Washington, DC

Common symptoms and likely causes

How DC water plays in

DC Water describes its water as moderately hard, typically about 70 to 120 ppm (3 to 9 grains per gallon), varying by location and season. That is not extreme, but over years some calcium and magnesium will settle in a tank or coat electric elements. Flushing the tank through its drain valve now and then helps. The water is also treated with chloramine and orthophosphate for disinfection and corrosion control, which is worth mentioning to a plumber if you see unusual wear on fittings or anode rods.

Safe checks before calling

• For electric heaters, look for a tripped breaker in the panel.
• For gas heaters, confirm the gas valve is on and other gas appliances work.
• If the pilot is out, relight it only by following the instructions printed on the heater.
• Never cap or plug a relief valve that is releasing water. It is warning you about pressure or temperature.

Basement and closet installs

Most DC water heaters sit in basements, utility closets or under stairs in rowhouses and condos. Tight spaces make access slower, and a leak can go unnoticed until it reaches a finished floor or the unit below. A drain pan and a quick look at the base every few months catch trouble early.

Fix it or replace it

A heater with a dry, sound tank and one failed part is usually a good repair candidate. When the tank is rusting or weeping, or when the repair is costly on an older unit, replacement is often the better spend. The plumber can show you the age on the data plate and talk through the choice.

What affects the price

• The part that failed and whether it is in stock
• Gas versus electric
• Access in a cramped basement or closet
• Visits outside regular hours
