A rough-in assembly for mounting a free-standing faucet on a floor is revealed. The rough-in assembly includes a mounting base, a connection tube set having cold-water and hot-water connection tubes, a fixing plate, and a plurality of nuts. The mounting base consists of a bottom plate fixed on a laminated wood, a tube-fixing portion positioned on the bottom plate and provided with two locking slots, and a plurality of bolts projecting from the bottom plate and inserted through a mounting hole on the floor. The cold-water and hot-water connection tubes are locked in the two locking slots of the tube-fixing portion. The fixing plate allows the bolts of the mounting base to pass therethrough. The nuts are threaded on the bolts for fastening the fixing plate on the floor. Thereby the free-standing faucet is secured on the floor firmly and production cost is dramatically reduced.

An on-basin installation device of a faucet is provided, wherein a basin surface is disposed with an installation hole. The device includes an installation seat, for installing the faucet above the basin surface and disposed with a limiting hole; a fastener, disposed with a first connection hole and a second connection hole; a driving member, disposed with a driving part at one end thereof, wherein the driving part abuts to a top surface of the installation seat, another end thereof passes through the limiting hole and the installation hole to extend below the basin surface, and a portion thereof extending below the basin surface penetrates the first connection hole and is screwed with the first connection hole; and an anti-rotation member, with one end thereof fixed to the installation seat and another end thereof penetrating the second connection hole and abutting to a side wall of the second connection hole.

A faucet mounting structure includes a threaded pipe and a threaded lock nut. The quick tighten and release adjustable lock nut includes a separate upper main body and a lower main which snap fit together. The upper main body includes downward extending lugs with inward facing threads which are urged against the outward facing threads of a faucet pipe to hold the pipe and thus, hold the faucet in a fixed position on a counter top. The downward extending lugs are captured in canted arcuate recesses in the lower main body. The canted arcuate wedge shaped side wall ramps biases the threaded lugs outward decreasing the diameter of the inner bore and pressing against the pipe threads as the lower main body is rotated clockwise with respect to the upper main body enabling the lock nut to slide upward over the threaded shank of the faucet until abutting the top portion of the threaded faucet pipe whereby rotating the lock nut causes cooperative engagement between the threaded lugs of the lock nut and the threaded faucet pipe tightening the lock nut threads around the threaded pipe.

A faucet assembly and related mounting method is disclosed. The faucet assembly requires only a single fastening mechanism to secure the faucet assembly to a mounting deck. Locating members positioned in alignment with fluid source pipes and their corresponding valves ensure proper placement of the faucet assembly relative to the mounting deck.

A rough-in assembly for free-standing faucets is revealed. The rough-in assembly having at least a part thereof fixed under a floor includes a base, a first water-contact member and a second water-contact member separated from each other and disposed on the base, and a sleeve mounting seat connected to the base and provided with a top plate portion extending across the first and second water-contact members. Two first hollow-out holes are arranged at the top plate portion and corresponding to control valve sets of the water-contact members respectively. The top plate portion is also for installation and positioning of the free-standing faucet. The position and the direction of least one of the water-contact members can be adjusted so that the rough-in assembly is adapted to use in different water supply pipe arrangements. The disposition of the sleeve mounting seat ensures stability and aesthetics of the free-standing faucet.

A tool and method for a faucet installation is disclosed. Both sides of the T-shaped flange are provided with screw holes, guide grooves, a first step, and a second step. A tightening screw is arranged in the screw hole, and the tightening screw is threadedly connected with the tightening component. The tightening screw controls the tightening part in the T-flange to rotate and unfold from the first step, and then fit in the guide groove and tighten upward, tighten and fix the T-flange in the faucet fixing hole of the sink, and then connect and fix the faucet with the fixing device to realize the operation and installation of the faucet on the front of the sink. The fixing device can be installed and fixed by rotating the two tightening screws in the positive direction.

Provided is a liquid dispensing device. The liquid dispensing device includes an internal member coupled to a sink and a nozzle. A liquid processing module is installed separately from the dispenser and may include components to generate, for example, a heated liquid, a cooled liquid, or a liquid having a sterilizing agent. Piping coupling the liquid processing module to the nozzle may extend through the internal member, and one or more components may couple the internal member under the sink. One or more valves may be positioned on the piping to direct fluid from the liquid processing module to the nozzle or to discharge fluid.

A faucet apparatus and method of implementing a faucet apparatus are disclosed herein. In an example embodiment, the apparatus includes a body integrated or coupled to a base, where the body includes surfaces within which are formed first and second orifices that respectively extend inward into the body along first and second axes, respectively. A first cross-section of the first orifice taken perpendicular to the first axis has a first size and a first shape that are, respectively, substantially identical to a second size and a second shape of a second cross-section of the second orifice taken perpendicular to the second axis. The apparatus also includes a spout having a first end supported within the first orifice, and a sensor structure having a cross-sectional surface supported within the second orifice, where each of the first end and cross-sectional surface is configured to fit complementarily within either of the orifices.

A faucet trim assembly includes faucet body subassembly and a base subassembly removably coupled to the faucet body subassembly. The faucet body subassembly includes a spout, an escutcheon coupled to the spout, and a handle coupled to the escutcheon. The spout includes a first internal passageway. The base subassembly includes a valve cartridge that is removably coupled to the base subassembly. The valve cartridge is configured to control a flow of water through the spout. The base subassembly is configured to removably couple to a sink deck independently from the faucet body subassembly.

An on-basin installation device of a faucet is provided, wherein a basin surface is disposed with an installation hole. The device includes an installation seat, for installing the faucet above the basin surface and disposed with a limiting hole; a fastener, disposed with a first connection hole and a second connection hole; a driving member, disposed with a driving part at one end thereof, wherein the driving part abuts to a top surface of the installation seat, another end thereof passes through the limiting hole and the installation hole to extend below the basin surface, and a portion thereof extending below the basin surface penetrates the first connection hole and is screwed with the first connection hole; and an anti-rotation member, with one end thereof fixed to the installation seat and another end thereof penetrating the second connection hole and abutting to a side wall of the second connection hole.
