Newbie here, I just had my pool installed and today the electrician came and wired everything for me. I did all of the pvc piping. When I started my super pump, it seems to run hot and I get air bubbles coming out of the return line, everything I read seems to indicate it this is caused by air leaking in the suction lines, but it seems like I have good tight joints, any thoughts? My pump is about 30 feet away from the pool.
