The manual says that a diverter valve can be installed for vacuuming to waste during heavy spring clean up or pulling rain water out of the pool. Where would it be installed? Do you sell this valve?

Yes we do carry this diverter valve which you may view or purchase through this link http://www.inyopools.com/Products/07501352023400.htm This valve has 3 ports on it, the valve would screw into the disharge side of your pump and you can have the handle turned so the return water goes through your filter or you can turn the valve in the opposite direction so the dirty water goes to waste and bypasses your filter, this is very helpful when vacuuming or for heavy spring clean up.

Why buy a more expensive Hayward de pool Filter if this one says in ground all types all sizes EC40a or ex 50a

Warren, You would have to match the filter size with your pump GPM. That's how you determine what size filter to get, the bigger the filter the better.
