Abstract
A pool filter for use in pool piping or other fluid conveyance system. The pool filter may include a housing defining a fluid chamber for receiving one or more filters. Multiple openings may be defined in the housing for receiving and removing fluid from the fluid chamber. The openings may be approximately the same size and may be located on the housing at similar elevations and/or radial sectors. One or more footings may be joined to the housing. Each footing may include a base portion for receiving anchor members to anchor the housing to a support surface. The footings may be designed to transfer to the support surface predetermined lateral or other forces imposed upon the pool filter by events such as earthquakes and hurricanes. The footings may be separate components joined to the housing by tabs and/or mechanical fasteners.
