    Welcome!

    What you describe makes no sense. Unless the plumbing was hooked up wrong. Could you upload a picture of the plumbing?

    Welcome to the forum.

    When you set the multiport to "recirculate" you get 10 psi and water flowing throuvgh the pump, right?
    Are their any bubbles in the pump basket at that time? The pump basket should be full of water and flowing...is it?

    Did this start just after you hooked up the brand new sand filter?

    maybe check the spider gasket in your multiport valve?
