Last year I had a small Intex Easy Set and knowing I would be upgrading this year, I purchased and hooked up a Hayward 1HP 16" Sand Filter. The filter was winterized and is already loaded with sand.
On to this year we have set up an Intex Ultraframe 18' x 48" pool. I have made all of the modifications to use the sand filter again. I am just not sure of the process of opening a sand filter that already has sand in it. Am I supposed to take the top valve off again and fill it with water like I did when I added sand? Am I just supposed to let gravity prime the pump/filter then backwash and rinse before I set it to filter setting?
Any advice is greatly appreciated.
