I just recently had the question asked of me of, when do you need to install a thermal expansion loop in CPVC piping? I searched all of the manufacturers that I could think of and they all appear to say basically the same thing, in long straight runs of pipe. No one specifically defines what that length would be and likewise I could not find an allowable expansion amount. For instance an expansion of ½" or 1" is acceptable or at 1" expansion you will need one. I can understand not defining a specific length of run since each geographic area has different temperature changes which would affect the expansion, but I would have thought that they would define an expansion threshold. Any guidance that can be given would be greatly appreciated.
