Water Heater Repair in Rockville, MD

Who handles a water heater permit in Rockville?

It depends on who supplies your water. The City of Rockville runs its own water system for about 70% of the city, and WSSC Water serves the rest. Rockville's Express Water Heater Permit Guide says City-water addresses apply to the City's Department of Community Planning and Development Services online through MGO Connect, while WSSC-water addresses get the permit from WSSC Water. The City publishes a Water Service Provider Map, and your water bill also shows which utility you have. Simple repairs such as a new element or thermostat generally don't involve either office; a replacement does.

Does Rockville's water affect how long a heater lasts?

City water is drawn from the Potomac River, treated at the City's own plant and disinfected with chlorine; the plant switched from chlorine gas to liquid sodium hypochlorite. The City buys water from WSSC, which is also Potomac-sourced, when its plant is offline. WSSC-served streets get WSSC's own treated water. Neither difference changes how a tank works, but Potomac water carries enough minerals that sediment builds up on the tank floor over the years, which is why plumbers suggest a periodic flush and an anode check.

Is my heater worth fixing at this age?

Rockville's median home was built around 1980, per census-based figures, which means a mix of postwar subdivisions such as Twinbrook and much newer development near Town Center. Most houses are well past their original heater. The useful question is how old the current tank is and whether it is dry. A dry tank with a failed thermocouple, igniter, element or thermostat is usually a repair. Rust at the base, water seeping from the jacket or a string of repairs on an older unit usually points to replacement, which is when the permit question above comes in.

One local note

Washington Gas is the main gas utility across Montgomery County. If you smell gas near the heater, leave the house first and don't touch switches or try to relight the pilot. From outside, call 911 and Washington Gas at 844-WASHGAS (927-4427), option 1. In Montgomery County, gas water heater replacements also have to be done by a plumber or gasfitter holding the required license for gas work, so this is not a weekend project for a homeowner.
