Our plumbers have not returned our calls to move some lines in our house so that we can finish our basement. They did the original installation and put in the Pex line that expands over the fittings. Soo.. we decided to move these on our own. Bought the tool, all fittings and line, watched an online video to see how the tool worked. When we were done, we turned on the water and at almost every connection there is a slow drip. I did not expect this at all after the research I have done on this. Is there something I am missing? Should we wait a certain amount of time for the line to shrink down? Does heat need to be applied? Unfortunately, there is only one plumber in our area that works with this. There are no supply stores in the area so I feel as though I am at a loss here. Any help would be extremely appreciated. Very frustrated right now.
