Installed a new 80 gallon electric Bradford white hot water. I isolated the old hot water heater and drained it out. Once the system was drained I disconnected the wiring and cut the copper lines. Installed a new 80 gallon electric hot water heater and used 3/4 copper pro press fittings. I made sure all the wiring was wired properly. I opened the cold water side and checked my fittings for leaks. Once the system was filled I powered the system up. I let the homeowner know it will take a couple of hours for the water to heat properly. The system is operating properly at this time. Model #Sle280t6-1sevv, serial #Yl50525329.
