Ecomatic Salt System..

do I dare ask for opinions on the quietest 1.5 hp pump to install

Quiet 1.5 hp pump? What kind/size filter do you have? I like the NorthStar pumps by Hayward. They are strong, effecient and pretty darn quiet as well . . . if you do consider a NorthStar pump, keep in mind that they are full or max rated so their gpm output is much greater than another pump of the same hp. You may want to post this over in the equipment section of the forum for more helpful advice about pumps . . .

Hope this is helping you.

Another thing, you may want to read this before deciding on a pump/filter combo (see link below). . . you need to be especially careful about your pump's water turnover rate when adding a salt cell. You need to run those things at least 6 hours a day to generate enough chlorine and there really isn't any need in turning your water over 3 times in 6-8 hours . . . not saying your oversizing your pump(you're at 21k, right?), but just something to consider . . . a flow rate of 50gpm would turn your water over in a little under 8 hours . . . The general rule for a energy effecient system with good filtration is to oversize your filter and not oversize your pump, don't undersize it either . . . there is a nice balance that can be reached here . . .
