Upon arrival, clients water heater was leaking from shark bite flex supply lines. Unit is from 2015. Went over different options from repair to replacement. Client authorized me to just repair for now. Shut water off to water heater, drained it down some. Removed hot and cold shark bite flex lines. Installed new stainless flex lines, soldered in. Had to loop cold supply because of lack of space. Turned water on, purged air from system at all points of use. Tested and everything working properly. 1 year warranty parts and labor. Emailed estimates to client for replacement in future.
