Inventors:

Mark A. Porter - Phoenix AZ

International Classification:

B01D 2446

US Classification:

210 95

Abstract:

A swimming pool backwash filter which separates backwash contaminates from the backwash water so that the may be discarded separately, for connecting to a standard pool filtration system, having a pump with a pump inlet and a pump outlet, a sand filter having a sand filter inlet and a sand filter outlet, and having a pool return and a pool skimmer connected to the pump inlet, comprising: a backwash valve and a backwash filtering system. The backwash filtering system having an inlet and an outlet and a filter element disposed between the inlet and outlet, the outlet connected to the pump inlet. The backwash valve having a normal position and a backwash position. When in the normal position, the backwash valve connects the pump outlet and sand filter inlet, and connects the sand filter outlet and pool return. When in the backwash position, the backwash valve connects the pump outlet and sand filter outlet, and connects the sand filter inlet and backwash filtering system inlet.
