A tub has a wall mounted spout from which mixed hot/cold water flows into the tub below the max fill level of the tub. The spout preferably does not extend significantly into the tub and can be provided with a check valve and/or vent external to the volume of the tub.

A clearance gage that includes an elongated shaft having a first end and a second end, a gage element connected to the first end of the elongated shaft, where the gage element defines a first width and a second width measured perpendicular to the elongated shaft, where the first width is larger than the second width, where a thickness of the elongated shaft is not more than the second width, where the first width defines a size of the gage element to assess a gap clearance between two components, and a marker connected to the elongated shaft, where the marker is positioned at a predetermined distance from the gage element along the elongated shaft, where the marker defines a marker width measured in a direction perpendicular to the elongated shaft that is greater than the second width of the gage element.

The invention relates to auxiliary devices for a liquid supply means. The adapter with a liquid supply single channel consists of the upper component provided with the connection element and the portion of the single channel located in the upper component, and the lower component, which is provided with the ascending and the descending longitudinal pass-through portions of the single channel, the throttling means and the air gap. The portion of the single channel of the upper component is formed by assembling the connection element of the upper component to the lower component. A part of the single channel consists of the ascending longitudinal channel portion and the portion of the single channel located in the upper component and allows for the throughput of liquid to the throttling means at a uniform rate. The ascending longitudinal channel portion and the channel portion of the upper component which are in fluid communication with each other have a preferably identical cross-section. The connection element of the upper component is made in the form of an arc-shaped recess located inside the upper component. The external upper surface of the lower component has a protrusion which follows the shape of the recess, with the groove along the entire length of the protrusion, that follows the shape of the protrusion and limited by two side walls. The portion of the single channel located in the upper component is formed by connecting the upper and the lower components by internal free space of the upper component recess and the groove of the lower component protrusion and is predominantly arc-shaped.

A backflow prevention device including a tank inside of and moveable relative to a housing. A cap coupled to the housing and including inlet and outlet chambers fluidly connected through an inlet, the outlet chamber communicating with the tank. A shell is connected to the cap and includes a shell inlet chamber, which communicates with a first outlet hole of the inlet chamber, and a second outlet hole, which communicates with the tank. An inlet sealing member opens/closes the inlet to fluidly connect/disconnect the inlet chamber and the outlet chamber; and an outlet hole sealing member is moveable with the tank to open/close the second outlet hole. Closing the second outlet hole prevents water from flowing through the second outlet hole and switches the inlet from open to closed. Opening the second outlet hole allows water to flow through the second outlet hole and switches the inlet to open.

A vacuum breaker includes a main body, a bushing, an elastic member, a braking member, a water stop gasket, a water inlet disk and a washer. The interior of the main body is provided with a positioning groove. The bushing is made of metallic material and has an exterior provided with a positioning protrusion secured in and combined integrally with the positioning groove of the main body. The bushing is extruded outward by an oil pressure to form the positioning protrusion. Thus, the bushing is combined with the main body integrally and will not be detached from the main body.

A system separation device with at least one pressure-proof tank for containing a liquid that forms a predetermined liquid level in the tank, above which level there is a gas cushion. The device contains an inlet in the upper region of the tank for fluidly feeding the tank from a first fluid system, and an outlet in the lower region of the tank for forwarding the liquid to a second fluid system. To prevent the germ-infestation of the inlet, at least one germicide material is arranged in the region of a gas cushion above the liquid level

A vacuum breaker having a supporting rib and a skirted section is disclosed. The supporting rib is configured to be axially aligned with air slots in an outlet tube and provide a more robust vacuum breaker sleeve under extreme operating conditions. The skirted section can prevent leakage through air slots during high back pressure operating conditions.

A backflow inhibitor has a jet nozzle connectable to a flow entrance and has a capture part which captures the liquid jet that passes over a free jet path from the jet nozzle. The capture part is connectable or connected to a flow exit and to an outlet arranged below the free jet path. The outlet discharges a partial amount of liquid not captured by the capture part. The backflow inhibitor includes an insert cartridge which carries the jet nozzle and the capture part. In use, the insert cartridge is held such that the jet nozzle is connected to the flow entrance and the capture part is connected to the flow exit. The insert cartridge, in the cartridge section which is arranged between jet nozzle and capture part and which forms or delimits the free jet path, has at least one cartridge opening that can be connected to the outlet.

An anti-siphon system for use with an irrigation system, such as lawn sprinkling system is disclosed. The system includes a backflow prevention valve with a bonnet- and poppet valve system with a conical spring that biases a lower poppet valve head, and engages the valve body. The use of the conical spring simplifies the mechanism, while providing reliable backflow prevention.

A flushometer valve assembly comprises a flushometer valve body including an outlet, an outlet tube including a conduit extending along a longitudinal axis, and a flushometer valve tube-to-body coupling that directly fastens the outlet tube to the flushometer valve body.
