We are in the final stages of changing our 16 x 32 vinyl IG pool into a sport/play pool. Our current pump is a ¾ HP Hayward Superpump which is 11 years old, noisy, but working! We typically run it 24/7 during pool season (Memorial to Labor day). We have one skimmer 20 feet away from pump and our piping is all 1 ½”. We have a 24” sand filter and are going to add a salt gen to our set-up. My question is what should we do as far as pump size/type ? Does it make sense to look at a 2-speed pump or should we stay with a single speed? Is the 3/4HP single speed too much pump and if so any drawbacks to continuing to use it ? We have 230V at the pool pad so does anyone know anyone who make a ½ or ¾ HP two-speed that is 230V or would we have to go 115V if we go two speed and if so does that make sense ??. Thanks for helping us out - if you can’t tell we’re newbies !
