This was an emergency dispatch. Upon arrival, customer informed me that his hot water heater was leaking from the top and it was dripping into the unit below. Customer had a 30 gallon 3800 W Rheem heater. I replaced the heater with a 28 gallon 3500 W Rheem heater. New heater provided with heater pan and all new piping. After piping the heater in with flex lines, I wired the electric and turned on the heater to make sure it was heating. Both elements were heating properly, and there were no leaks. Customer extremely satisfied.
