Abstract

See full text

The double-tier drain filter system includes an elongate base having an upper section and a lower section. A drain cover with perforations couples to the upper section, and the lower section couples to a drain pipe. Threads are provided between the lower section and the drain pipe to form a threaded interlock. A recess inside the upper section receives a filter assembly which includes a removable, perforated drain basket and a filter element inside the drain basket. An annular mount flange with threads extends from the bottom of the drain cover to thread into the matching inner threads of the drain basket forming another threaded interlock. The drain cover and the filter assembly serves as a double-tier, two-pass filter ranging from coarse to fine filtering, respectively. Tools are provided to facilitate installation and cleaning.
