What's the best method for removing debris? In my case, sand. In my Polaris 380, AKA Jeeves. I have tried searching the archives, taking the unit completely apart, clearing the jets by pushing the debris into unit via a stiff piece of wire, and lastly, a shop vac on the hose just below the backup valve while hitting the jets with compressed air. I really thought the shop vac trick would do it...
Thanks!
