My PB wants to give me 3 pumps for my pool. I'm wondering if they are all necessary. Info below.
95 perimeter ft in ground Gunite pool approx 17,000 gallons - 2 HP 2 speed pump
2, 18" water shears in a raised wall - 1 HP pump with wall switch
Polaris 280 - 3/4 HP booster pump
Are all of these necessary or will fewer pumps do the same jobs???
