The Hayward PowerFlo is a popular above ground swimming pool pump. The design of the Hayward PowerFlo is a sleek design with one flaw. The current design of the Hayward PowerFlo is a “top mount” discharge that can only be connected to a sand filter. If you have a cartridge or d.e. filter, you would typically need a new pump. The housing on the Hayward PowerFlo pump can be rotated to a “side-mount” discharge, which can be used on a cartridge or d.e. filter. This guide will show how to do this in no time.
