Plumbing Guys Take the lazy way out

Hot and Cold bundled together? Gee do you think maybe the hot may get a little chilly on its route to the faucet?
Not to mention different rates of expansion and contraction!

This is the ALMOSTcorrect way to run throughout the house. Line should be run in SMALL bundles allowing for expansion and contraction and to compensate for the weight of th water when full. It is likely that if all were filled this would detach fron the SMALL SINGLE clip (in center) holding all of these. DO YOU THINK? Apparently not!
