I am having a house built and the plumbing rough-in is complete. The water lines are PEX and there is a relatively long straight run (60') in the basement ceiling that supplies water to all the rooms above. I also have a return line for recirculating hot water because of the distance of the master bath from the water heater. All three lines (2-3/4" supply lines and 1-1/2" return line) are in the same set of holes in the joists running the length of the house. I have a feeling that since the hot water lines will always be hot due to the recirculation feature the cold water supply line will become warm. I have the plumber coming back tomorrow to discuss this issue and would like to know if there is a standard practice to separate the cold water supply line from the hot water line to avoid heat transfer. Is this a problem or just my imagination?
Thanx,
