After performing leak detecting I was able to locate leak in between the kitchen and dinning room. Gave customer two option. Performing a direct access repair. Or performing a re route for an additional 2400. Performed re route of customers hot line that was leaking. Ended up being half inch copper line that manifold behind water heater and came up between the two bathroom sinks. Eliminated this line and ran new water line above head. While working on customer water lines I noticed several different issues. Customer had several issues at manifolds behind water heater to include lot of corrosion on water line and old repairs that where not done properly. Also noticed both customers shower valves where leaking. Strongly recommend performing a full house repipe to prevent future leaks. Also while in the attic above the kitchen it appeared customer had a slight roof leak. There was a section of wet insulation which I believe to be from the rains that occurred yesterday
