Hi everyone – we are looking to build our first pool. It’s 20x40 and 7’ deep. We have a PB we like who has been building pools for 35 years, one at time, and is not big on up-selling believe it or not. His normal pool install is a Hayward single speed pump with 1.5” piping. Our power rates are low, ~$0.08/kWH, and I’m interested in what I read about the 2 speed and variable speed pumps (EcoStar) as well as 2” piping. This is all new to us…would love some feedback on recommendations for single/2/variable speed by Hayward and piping. Thanks!
