Copper pipes in Column/how to Attach?
Posted by casman on March 29, 19101 at 13:37:10:
I replaced the galv pipes in this hollow column with copper, do I need to worry about bellying of the copper pipes because they are only secured at basement level and second floor level; I can't get inside the column, its around 9 feelt vertically that is not secure...Also a new pvc drain line runs through,,,sounds like I may be in for a noise problem and I had the idea of filling up the entire column with expanding foam to serve 2 purposes, 1)securing the pipe and 2)dampning the noise. Sound like a plan?
