We have a Hayward Perflex EC50C90 filter. Bought it 2 years ago, sat in the box in the shed for one year - had new pool and this filter installed last April, 2015. Went to turn on this year and it is leaking alot around the main area where you lift up the filter head to see the filter "fingers". The gasket seems fine, but one of the 12 screws was not screwed right. Could this be causing all our leaking??
