Abstract: A bidet attachment system includes an attachment structure configured for removable attachment to a toilet bowl, a spray structure for spraying water, a rotatable dial located on a top side of the attachment structure, and a valve having an inlet section, a valve section downstream of the inlet section, the valve section regulating passage of water from the inlet section, an outlet section downstream of the valve section, wherein the outlet section includes a first outlet that allows for egress of water and a second outlet that allows for egress of water, wherein the valve section includes an adjustable control disc being mechanically coupled with the dial such that rotation of the dial rotates the control disc, the control disc having a first and a second channel bore, and a stationary disc downstream from the stationary disc having a first and a second channel bore.

Abstract: A fastener for fastening a bidet attachment to a toilet bowl is provided. The fastener has a base disc with a first elongated slot, and depressions on a top surface of the base disc. The base disc is configured for placement within a depression of the middle disc, which has a second elongated slot commensurate with the first elongated slot, a depression on a top surface of the middle disc, and protrusions on a bottom surface of the middle disc. Protrusions are configured to fit within the depressions when the middle disc is connected to the base disc. The fastener also has a top element configured to fit within the depression on the top surface of the middle disc, a third elongated slot commensurate with the first elongated slot, a portion of elastomeric material spanning the third elongated slot, and a slit located in the portion of elastomeric material.
