Morning. My Polaris booster pump needs to be replaced and I am trying to find info about which is the best for the booster pump replacement? There is so much info here about the most energy efficient pool pumps…almost too much on that topic…but I am not finding much about the booster pumps. So, my question is: What would be the best booster pump for my Polaris? And please help me consider the cost of the pump as well as energy efficiency. Thanks.
