I purchased a house recently with an inground 22x40 oval pool (~32,000gal) in poor condition. I am having the liner replaced and am working on replacing all of the plumbing and pump myself. Currently, we have a cartridge filter (Jacuzzi Triclops), chlorine feeder (Hayward C500CF) and heater (Raypak RP2100). I'm replacing the dead Sta-Rite pump with an IntelliFlo 4x160 and eventually hope to replace the cartridge filter with a DE filter and install a solar heater.
The plumbing was all 1.5" spa-flex and had more joints and fittings than I would think are necessary. My current plan is to use 2" through the pump, filter, and heater. This means each 1.5" intake pipe (there are three) will be upsized and connected into the 2". And the 2" return side will split into two 1.5" reducers for the two return runs. Does that sound right?
Next question - my local Lowes and HD only seem to have 2" fittings in schedule 40 DWV - can this be used for my pool plumbing?
Any thoughts, suggestions, critiques are appreciated.
