ABSTRACT:
A diverter valve, particularly adapted for use in septic systems, for controlling the flow of effluent from a septic tank to a plurality of leach beds, comprising a thick-walled valve body of cast urethane having a deep circular groove in the upper surface to receive a section of a capped pipe to afford access to the valve control from ground level, and having a centrally and vertically disposed valve chamber provided with an inlet port and a plurality of outlet ports, rigid integrally cast webs extending from the top to the bottom walls of the valve body dividing the same into separate inlet and outlet chambers communicating with the central valve chamber, oppositely disposed circular openings in the top and and bottom walls of the valve body, the walls of the openings providing bearing surfaces for a tapered valve plug of cast urethane having top and bottom circular sections and having a cut-away central section providing a passageway for alternatingly connecting the inlet port with one of the outlet ports. The valve plug has at its upper end an integrally cast short shaft extending above the top surface of the valve body, a cast urethane cap having a central opening to receive the valve plug shaft, the cap being removably attached to the valve body to maintain the valve plug in position, and a knob cast into the valve plug shaft, cooperating with a groove in the cap to limit the rotation of the valve plug and insure proper alignment of the passageway in the valve plug with the inlet and outlet ports in the valve body.
