I currently have an older Letro Jet Vac with booster pump. If I were to replace it with a Polaris 360 can I turn off my booster pump and just connect sweep to a return line? I currently have two return lines, plus the existing return line that was connected to the booster pump, plus two returns in each set of steps (2 steps). Since my booster pump needs replacement I am wondering if I can just go this route and save the cost of a booster pump...... Thanks..
