Just finishing up a long and costly pool remodel. The person who is doing my electrical hookup is a Pentair factory rep, so he wants to use all Pentair products, which is fine by me.
Definitely doing the VS pump.
He says I need to use a cartridge filter (quad 188594) because a de filter has 12 to 15 additional 90 degree bends in it. Says these bends require more pump pressure which somewhat negates the advantage of a VS pump, because it needs to run a higher RPM. Truth?
My city requires a backwash line hooked into a p-trap in the sewer system, which has already been installed.
