Installled Zurn PEX water supply in a new home single fam residental, The home is a ranch with a long 3/4 run from one end to the other. My installation of my mains were perfectly straight initially, But during the final inspection I ran the hot for a long time to fill the jet tub on the far end of the house. By the time the inspector and I made it to the basement the hot was completely serpentine from one end to the other. I anticipated some heat expansion but not to this extent! Well, the inspector intially approved the job then called me the next day and left a message indicating I needed to take some corrective measure's, but did not specify. I will try to talk to him on Monday. In the meantime, called my local Zurn representitve who could not offer any real solution other than an expansion loop. He also said I was the first to call with this kind of problem. The expansion loop may be the best idea for all I know, but I thought I would post and see if anyone has had this issue before and what they did to take care of it.
Thanks in advance,
K.
