Hi all, run into some issues with plumbing with my inground pool install. I thought I discussed and insisted on rigid underground plumbing pipes because of all the discussion on this forum. So on the install date( today), surprise, its flex spa PVC hose 1.5". It's not specified in the contract. The PB says that's what he has been been using for all his pools and he will pad and fill with gravel to protect it. What should I do now? We are texting back and forth with the PB right now. Any suggestions?
