I am still fairly new to pools and just moved my 2hp hayward pump/cartridge filter onto my deck around the 18' Intex pool. The plumbing is slightly up hill and then turns into about a 12" 90 deg up then into the pump and I have to manually prime the pump everytime to keep the water flowing. I understand gravity and all, but I figured with the 2hp pump it would pull the water through easily. Is this simply not going to work and I just need to move the pump back downhill, or is there a type of in line primer I can install or something? Sorry for the lack of pictures.
