We are in the process of opening in ground salt pool 16 x 32 (shock stage) overnight we lost 3/4 of our water through the black vinyl drain hose while the filter was running.
Can anyone shine some light on this. New vinyl, new sta-rite multi port module, new dyna pro centrifugal pump all last year.
I'm leaning towards gasket on module but I have no idea. Thank you in advance.

Is the multiport set to filter or waste?
