Safety Alert: Installation Restrictions Regarding Masonry Chimneys

Why does WSSC Water Inspect Gas?

WSSC Water is charged by the State of Maryland with permitting and the inspection of all Natural and LP gas installations within Montgomery and Prince George’s counties of Maryland.

WSSC Water is also charged with the enforcement of gas related regulations found in the WSSC Water Plumbing and Fuel Gas Code. WSSC Water was given the authority under provisions of the Annotated Code of Maryland and provisions found in the Maryland Public Utilities Articles. Gas appliances can release deadly carbon monoxide (CO) if not properly installed or due to malfunction. For over 40 years, WSSC has taken great pride in protecting our customers.

For your safety, WSSC Water permits and inspection are required for these new/replaced gas appliances:

  • Furnaces and boilers
  • Water heaters (Tank type or Tankless)
  • Gas logs
  • Dryers
  • Ranges and cook tops
  • Outside gas grills (if attached to natural or propane gas)
  • Gas lights
  • Fireplaces
  • Room heaters and generators.

NOTE: Be certain that only WSSC Water-licensed individuals perform installations and have the required WSSC Water​ permits. An important WSSC Water inspection must be performed within 10 days for the safety of your family and home.
