Abstract
A helical drain for a toilet is disclosed. The present invention relates to a novel toilet drain configuration. Specifically, the novel toilet drain configuration comprises a helical loop trapway. The drain of the present invention exits the toilet bowl and forms a substantially vertical tubular loop running generally parallel to the width of the bowl or stool, or perpendicular to the longitudinal axis of the bowl or stool, before being connected to a sewer. The drain of the present invention functions like a P-trap syphon in removing the contents of the bowl. The diameter of the looped tubular portion of the drain may vary by approximately 20 percent or less in the direction of the sewer connection. Sensors may be placed on the drain to monitor drain contents, fluid levels, and drain performance. The drain may be fitted with valves to control the flow of fluids and gases through the drain.
