Yes the Hayward Pro Grid DE Filter 60 Sq Ft is a complete filter, including the grids, but you will need a backwash valve. The Hayward 2" Slide Valve for DE Filter is the correct valve that connects to the Pro Grid Series of Hayward D.E. Filters. You would not need anything additional for a complete installation, with the exception of possible re-plumbing of your existing pipe work.
