I need to upgrade the pool equipment for a 40k gallon pool with spa (4 pool return lines, farthest return line at ~ 40-50 ft).
Former setup: 1 WhisperFlo 1.5hp , 1 pump (Century) for pool cleaner, 1 pump (Purex) for spa jets, 2 mechanical clocks, filter (DE, broken), missing heater
New equipment: 1 Intelliflo 4x160 (3050), EasyTouch 4 + IC40, Sta-Rite SR400NA Max-E-Therm heater, Hayward C425 filter
A pool guy recommended using 2.5 in PVC pipe ( not carried by Home Depot or Lowes) for plumbing (above ground) , even though underground it's only 2in PVC.
Will this actually help? Any thoughts will be appreciated.
