We are about to make our choice of PB and design. One guy uses a Hayward and the other Pentair equipment. In my youth, we had a pool- nothing like what is around today- but the pump, when new or old was a screamer- It was loud and if you were swimming you wanted it off because of the noise. How loud are the two above pumps? How far away do most of you place them? I checked my neighbors but his is quite some distance from the spa. Do I try to place the spa and pool pumps as far away as possible (costlier) or are they quiet ?
