Question on pumps. We are using a Tristar 0.5hp pump for our pool, but only have 1.5 inch line. The issue, I am told, is that the Tristar pump cannot draw enough water through an 1 1/2" to completely fill the basket, it needs 2" plumbing for that. It just so happens that this was an afterthought and the pool does not have a 2" suction line. I am also told that if we had a 1 HP Superpump installed there would be no air and there should be no air in your initial pump. Despite all of this, I am also told that the air in the pump does not cause any issues, the heater and salt system will still work with more than enough pressure . Thoughts from the brilliant minds in this group?
