Water Heater Replacement in Waldorf, MD

Who handles the permit for a Waldorf replacement?

Charles County's Department of Planning and Growth Management runs Codes, Permits and Inspection Services out of La Plata (301-645-0692). The county building code adopts the International Plumbing Code and the International Fuel Gas Code, which set the rules for relief valves, venting and gas connections on a new heater. Ask the plumber you hire whether your swap needs a permit and who pulls it. A plumber who works in Charles County regularly will know the routine, and it's worth getting that answer in writing with the quote.

What is Waldorf water like for a new tank?

The Charles County Department of Public Works runs the Waldorf Community water system. Most of its supply is groundwater from 18 deep wells in the Patapsco and Magothy aquifers, blended with surface water the county buys from WSSC Water, and it's disinfected with chlorine. Well water and river water carry different mineral loads, so the county's annual water quality report is the place to check before you decide on a softener or a tankless unit. Either way, flushing sediment from the tank once a year helps any heater last.

Is my Waldorf house likely to need extra work?

Usually less than in the older inner suburbs. In ZIP 20603 only about 6 percent of homes date from before 1980, and most were built between 1980 and 1999. That means many heaters failing now are second or third replacements in a garage, utility closet or basement that already meets most modern layouts. Even so, a newer code can call for an expansion tank, a drain pan or a longer relief line, and a gas unit's venting has to be checked against the new model's requirements.

Washington Gas supplies natural gas in Charles County. If you smell gas near the heater, get everyone out of the house first. Then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1, from outside.

A local note

Charles County also requires a reduced pressure zone backflow assembly on lawn irrigation systems, tested every year. That doesn't affect the heater itself, but if your irrigation tie-in sits near the water heater in a utility room, it's a good time to have the plumber look at both. For water service questions, the county's Utilities Division is at 301-609-7400.
