Abstract
A pump and filtration system for a pond or pool. The filtration mechanism has a filter member in which water with suspended solids in it is forced through the filter member to clean the water. The filter member is positioned in a housing and separated from the walls of the housing by a screen-type separation member. A water jet member increases the flow of the water entering the housing. The filter member is cleaned and solids are flushed from the housing in a backflush procedure.
