I was given a 1999 Morgan Daytona hot tub. Its 7 foot by 7 foot and the pack was just changed out a few years ago and still working great. The problem is the entire wood frame and skirt has rot damage. I have it flipped over and building the frame. While pulling the foam off to get the frame to fit I broke a barb off of a air manifold. Is there anyway to repair it without replacing both manifolds and check valve? Also what size is the pipe 1"? If I have to replace both manifolds does it glue straight onto the flex pipe and will normal pvc cleaner, primer and glue work?
