I don't understand the 1.5" either when looking at the posts here, but I talked to multiple builders and they all said the same thing. That is why I am questioning that maybe the fact that they were running separate lines makes up for it. It is hard to imagine they are building that many pools and don't know what they are doing -- these are companies that build 300-700 pools a year. I will push hard to upgrade to at least 2" everywhere.
I asked every pool builder I talked to about 2 speed pumps and they all glazed over. My thought on that was build it as they usually do and when I gain more knowledge, replace the pump if I understand it well enough and think the savings will outweigh the cost.
I've read about your pool build eljefe, your pool looks great. So can a 1 HP pump drive 8 spa jets? They wouldn't allow me more than 6 even with the 2.5.
Thanks for the answers.
