  • Patent number: 10437263
    Abstract: A fill valve for receiving a fluid flow includes a lower pipe and a flow restrictor cartridge. The flow restrictor cartridge is received in the lower pipe. The flow restrictor cartridge receives the fluid flow at a first fluid flow rate and provides the fluid flow as a second fluid flow rate lower than the first fluid flow rate. The flow restrictor cartridge includes a receiver and a compact flow restrictor. The compact flow restrictor is received by the receiver. The compact flow restrictor is configured to facilitate the reduction from the first fluid flow rate to the second fluid flow rate.

  • Publication number: 20170247871
    Abstract: A tankless toilet includes a bowl, a trapway, and a jet. The bowl includes a rim at an upper portion of the bowl and a sump at a lower portion of the bowl. The trapway extends from the sump to a drain. The jet includes a main channel configured to receive a supply of water from a supply conduit, and a plurality of distribution channels configured to introduce water received from the main channel to at least one of the sump and the trapway. The jet is configured to receive the supply of water from the supply conduit at a first flow rate and induce a flow from the supply of water into the trapway at a second flow rate greater than the first flow rate to prime a siphon within the trapway. The second flow rate is greater than the first flow rate prior to priming the siphon.
