Problem solved.....(drum roll).....It was the adjustable flow restrictor valve on the in-side. Manual said it was set by the factory to be full open. When I tried to move the valve, it was stuck and needed slight help from a plyers. Bottom line is was only 3/4 open. Fixed

Thanks to all who commented here.
