I just replaced the ball and cock mechinism in my toilet tank with the new "modern" Korky quiet fill valve and flapper. Everything works fine except the water does not refill in the tank unless I manually move the fill valve after flushing. Is there something I should be checking in order to have this operation work automatically?

I don't think understand that statement. Could You elaborate?
