Sewage effluent distribution means

In a septic system including a distribution tank for distribution of effluent to a plurality of fingers in a drain field, the improvement comprising an effluent-operated valve in said distribution tank for controlling the distribution of effluent from the distribution tank, including a distributing valve element having a closed bottom, a side wall with a plurality of spaced openings, and an inlet-forming open top with a valve-forming flange surface;

• and
• a valve closure element having a peripheral seal-forming surface adapted to engage the valve-forming flange surface of the distributing valve element and to close its inlet-forming open top, a buoyant member connected with the valve closure element, and means carried by the distributing valve element and forming a guide rod in sliding engagement with the valve closure element, wherein said buoyant member can move in reaction to effluent in the distribution tank to raise the valve closure element and open the inlet-forming top of the distributing valve element, allowing effluent to enter the inlet-forming open top and flow simultaneously from the plurality of spaced openings in the distributing valve element and to lower the valve closure element, as effluent flows from the distribution tank, into sealing engagement with the valve-forming flange surface of the distributing valve element, said valve closure element being guided in said movement by said guide rod.

In a septic system including a distribution tank for distributing effluent to a plurality of fingers, the improvement comprising an effluent-operated valve in said distribution tank for controlling the distribution of effluent from said tank, comprising an outer outlet-forming element having an open inlet adjacent its bottom and a cylindrical sidewall with a plurality of spaced outlet openings;

• an inner valving element slidably and rotatably carried within said outer outlet-forming element, said inner valving element having an open bottom, a cylindrical side wall with a single opening, and a body of buoyant material connected with said inner valving element, the outside surface of the cylindrical side wall of the inner valving element having formed therein a sawtooth camming surface and the inside surface of the outer outlet-forming element carrying a camming protrusion engaged with the sawtooth camming surface of the inner valving element, wherein said buoyant material connected with said inner valving element can react to effluent in the distribution tank to raise the inner valving element and as a result of the engagement of the camming protrusion and sawtooth camming surface, rotate the inner valving element thereby locating the single opening of the inner valving element in alignment with one of the plurality of spaced outlet openings of the outer outlet-forming element to allow effluent to flow from the distribution tank through the open inlet of the outer outlet-forming element and the open bottom of the inner valving element and through said one of the plurality of spaced outlets, and wherein the flow of effluent from the distribution tank lowers the inner valving element while allowing effluent to flow from the distribution tank and positioning the sawtooth camming surface of the inner valving element with respect to the camming protrusion of the outer outlet-forming element so that subsequent upward motion of the inner-valving element in response effluent in the distribution tank will advance the single opening of the inner valve element into alignment with another one of the plurality of spaced outlet openings.

A system for disiributing the effluent of a septic system to a plurality of fingers in a drain field, comprising

• a distribution tank for receiving effluent to be distributed to the plurality of fingers,
• a first effluent-operated valve in said distribution tank;
• said first effluent-operated valve having a valve body with an inlet opening and an outlet opening, and a valve element connected with a buoyant element and operated by accumulated effluent in said distribution tank to allow effluent to flow through said inlet and outlet openings of said valve body, and upon the depletion of the effluent in said distribution tank to stop the flow of effluent through the inlet and outlet openings, and
• a second effluent-operated valve in said distribution tank having an inlet opening and a plurality of outlet openings, said inlet opening of the second effluent-operated valve being connected with the outlet opening of the first effluent-operated valve, each of the plurality of outlet openings being connectible with a different one of the plurality of fingers,
• said second effluent-operated valve having a valving member with a single opening driven by connected buoyant material, said valving member being operated by effluent in said distribution tank to lift and rotate the valving member and align its single opening with different ones of the plurality of outlet openings, thereby allowing effluent to flow from the distribution tank to a finger that may be connected to said different ones of the plurality of outlet openings.
