Just learning there have been problems in PEX and Copper both for hot water circulating lines. Is it the hard water wearing out connections? Builder saying a timer will almost surely fix the future potential problems. That small doubt is concerning. We haven't designed the system yet but i'm thinking having a timer, and then run a larger diameter circulating loop (1.5") then branch off of it to every tap. The branches wont be hot but should be close enough to the loop that it wont take long for hot water to hit each tap.
