I do work at this condo complex which has two 2" pumps on it's swimming pool. THe weirdest thing happens. I recently installed new piping with new ball valves and also Jandy check valves both before and after the pumps. Twice since I installed everything, the pvc union nut on the outlet of one pump will deform. There is a short piece of 2" pvc between that and the check valve which also deforms(bulges outward) and then pops out of the nut. It looks like it's melted....but it could be presssure related also. Does anyone have any ideas or has anyone encountered this before? Thanks.
