I have a 20x48 proseries pool we will be getting rid of the black motor and exchanging it for an intex sand filter. I bought all the items to vacumm the pool but cant find the right size skimmer vacumm adaptor/plate to hook the hose to. The one I recently bought was a vacumm plate that fits jed, olp, wp but was to big for mine. I don't know what model my skimmer is so its hard to match it to the right skimmer plate.
