    Abstract: A flush toilet according to the embodiment includes a main water guide channel, a downstream-side water guide channel, and a convex part. Through the main water guide channel, flush water supplied from a water supply source flows. The downstream-side water guide channel on a downstream side of the main water guide channel spouts the flush water from a water spout port of the downstream-side water guide channel. The convex part is formed in the downstream-side water guide channel. The convex part includes a first guide part that guides upward the flush water flowing through the downstream-side water guide channel, and a second guide part on a downstream side of the first guide part which guides downward the flush water.

    Abstract: A siphonic flush toilet system and method of priming the same having a toilet bowl assembly comprising at least one jet flush valve assembly and at least one rim valve; and bowl having a rim and a jet defining at least one jet channel. The bowl has a closed jet pathway to maintain the jet channel in a primed state with fluid from the jet flush valve assembly to prevent air from entering the closed jet pathway. Flush valves may have back-flow preventer mechanisms and/or at least partly flexible valve covers, including specific valve cover structures. Flush activation assemblies may have a flush activation bar connected to the pivot rod and/or an adjustable flush connector located between the pivot rod and the flush activation bar. A kit providing one or more flush activation elements is included. The kit elements may be usable with the toilet systems and methods described.

    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.
