Patent number: 8910662Abstract: A diverter valve may include a body portion and a lid portion. The lid and body portions may define a fluid chamber. The lid portion may include a first stop and a second stop. A closure member may at least partially be received within the fluid chamber. A movable member, such as a handle, may be operatively associated with closure member. The movable member may be selectively movable relative to the lid portion between the first and second stops. A stop member may be selectively positioned on the lid portion. When positioned between the first and second stops, the stop member may limit movement of the movable member to between the stop member and one of the first and second stops. The first stop, the second stop, or both, may also comprise a stop member.Type: GrantFiled: December 13, 2010Date of Patent: December 16, 2014Assignee: Zodiac Pool Systems, Inc.Inventors: Randy Tan, Chad Hamilton, James T.

Patent number: 8137545Abstract: 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.Type: GrantFiled: September 13, 2010Date of Patent: March 20, 2012Assignee: Zodiac Pool Systems, Inc.Inventors: David B.
