In Chantilly, a disposal that stops is usually jammed or tripped, and a wet cabinet usually means a loose connection or a worn seal. A plumber can check the unit and the drain beyond it and tell you whether repair or replacement is the smarter spend. Call the number on this page to be connected with a local plumber in Chantilly.

Is my Chantilly disposal old enough to replace?
Possibly. Chantilly is an outer suburb built up largely in recent decades around the Route 50 and Route 28 interchange, and the median home dates to about 1987. A kitchen of that age has usually been through at least one disposal already, and many original units were basic models. If yours leaks from the housing, jams every week with ordinary use or grinds loudly with nothing in it, a new unit is usually the better value. A one-time jam, a tripped reset or a loose clamp are normal repairs.
Water here comes from Fairfax Water. Some customers get Fairfax Water's own treated Potomac and Occoquan water, and some get water through the Washington Aqueduct. At Fairfax Water's Potomac plant, total hardness runs about 70 to 185 mg/L, which leaves a modest mineral film on flanges and seals.
Will I need a permit?
Fairfax County Land Development Services lists like-for-like fixture replacement in the same location as exempt. New, repaired or relocated plumbing fixtures need a permit, applied for online through PLUS. A direct swap of an existing disposal usually stays simple, while adding one to a sink that never had it or moving the sink during a remodel may not. Your plumber can sort that out, and LDS answers questions at 703-222-0801.
What if the backup is bigger than the kitchen?
If toilets, tubs or a basement floor drain back up along with the sink, the clog is in the building sewer or the public main, not the disposal. Fairfax County says to call its 24-hour line, 703-323-1211, first when sewage backs up with no fixtures in use. If the county main is clear, the private lateral is the owner's responsibility, and a plumber clears it.
One local note
Many Chantilly kitchens have long drain runs from an island or peninsula sink to the main stack. Food paste tends to settle in those flat stretches of pipe, so a slow island sink is often a line issue rather than a failing disposal. Running cold water steadily while grinding, and for several seconds afterward, helps scraps make it all the way through.
