Completed Job

50-Gallon Electric Water Heater Replacement

Kingscup Court, Ellicott City, Maryland · Howard County · Water Heater Replacement

A 9-year-old Rheem electric water heater was experiencing electrical issues and had reached the end of its service life. Several code violations were present — the expansion tank was not strapped to code and the T&P discharge line was improperly terminated directly into the sump pump.

Replaced with a new Bradford White 50-gallon electric water heater. Installation included a new expansion tank properly strapped to code, a drain pan with 1" PVC drain line routed to the sump pump, and a 3/4" copper T&P relief valve terminated 6 inches above the floor per code. Hot side piping insulated to code. Corroded full port ball valve also replaced as a courtesy.

Permitted and inspected by Howard County. Work completed clean, to code, and passed inspection.
