I have a 21 foot above ground pool that sits in a 24x24 3 foot deep drop down in my back yard. I have always had the pool filter beside the pool and when I need to clean it (cartridge filter) it drains water out of the drop down and into the alley and the city threatens to give me a fine. Is it possible to place the filter on the ground above where the excess water would drain onto my yard. I have a waterway 150 sq foot cartridge filter and I need a new pump, but before I purchase a pump I wanted to know if I had to buy a specific kind to use if I was to move pump and filter. The place where I would move it would be no further than 4 foot from where it is now.
