I asked one PB some questions about the type and size of piping they are using for our potential pool build - a ~35,000 gallon, 20x40 foot pool with spa, grotto/waterfall, deep end, and in-floor popup's.
Q: Any use of “flexible” pipe?
Q: What size pipe do you use standardly?
A: vary by application generally main line 2" with 2" return line going to infloor, spa would use 2 1/2 inch suction, waterfall returns 1 1/2" return 2" suction, water leveler 3/4".
Does this answer seem ok? Seems to be a lot of discussions around this, and as usual, my head is spinning trying to figure out what is appropriate for us...thx for any help. I'm pretty anal, and expect to put this kind of detail in the actual contract. Amazing how little detail is in the bid they gave me.
