ABSTRACT:
The Strainer has a pipe with a multiplicity of holes, and surrounded by a mass of stones or marbles, confined within a double nylon netting. The pipe confines a one-way check valve. The mass of stones or marbles serves a dual purpose: weighting of the Strainer, and ancillary filtering of the fluid. The stones or marbles are of approximately three-quarters of an inch in diameter and, consequently, they have a multitudinous number of interstices which are not less than three-sixteenth of an inch in width, length and depth. These present virtually unlimited pathways, of gross dimensions, for the extraction of water.
