Abstract
Embodiments of the invention provide a pre-filter assembly for use with a pump. The assembly includes a housing having an intake channel and an outlet channel. The intake channel includes an intake flange around a first circumference and a ribbed surface to facilitate sealing. The outlet channel includes a bottom portion and an outlet flange around a second circumference. The intake flange and the outlet flange are on opposite sides of the housing. The assembly also includes a basket positioned in the housing. The basket has a bottom side and is positioned above the bottom portion of the outlet channel to form a chamber. The basket is positioned in closer proximity to the intake channel than to the outlet channel. In addition, the assembly includes a securing device with a lid having ridges and a clear top to permit the user to view the contents of the basket. The securing device also includes a locking ring with slots and openings to permit the user to view the contents of the basket.
