Also shown are the rainwater lines to feed our toilets and laundry rooms, as well as several outdoor spigots.
Routing the hot water lines from the collector to the tank won't be easy. The current plan is to locate the tank downstairs inside a wall separating the living room from the third bedroom, on the South side of the house. The lines must run downward continuously from the collectors to the tank. The only way is to go around the house, which will make the pipe run a little longer.
