Systems, apparatus and methods for providing air and water to hot tub jets. The present teachings include jet assemblies, manifold assemblies, and related components, as well as methods of assembling hot tubs involving these components. In some cases, the present teachings describe the use of dual extrusion tubing to route air and water through adjacent, connected fluid conduits. In some cases, the present teachings describe a press-and-click method of connecting various components.

A hot tub plumbing system including a plurality of water pumps respectively provided at different sides of a hot tub having a plurality of jets, and a plurality of manifolds each having an intake port coupled to one of the water pumps, and each configured to have a plurality of output ports respectively connected by tubing to one of the jets of the hot tub.

An apparatus and method for providing therapeutic bubbling massage of a person's body. The apparatus may be adapted to float on, for example, a pond, lake or pool. The apparatus may be formed of an inflatable bladder having an interior volume that is pressurized with air. The weight of a user disposed on the upper surfaces of the inflatable bladder may force a portion of the bladder below the surface of the fluid in which the apparatus is floating, such that bubbles are formed when the pressurized gas is allowed to escape the bladder through openings impacting the body of the user. The gas may be heated or may be infused with an aroma.

A hybrid spa has a power adapter connected to a 120 V outlet, a battery connected to the power adapter, and a plurality of spa components connected to the power adapter and the battery. The plurality of components includes a jet pump, a circulation pump, a main heater, and a controller. The battery powers at least some of the plurality of spa components and the power adapter powers the rest. The hybrid spa can further include a secondary heater connected to the battery and a power outlet. The secondary heater can assist the main heater when water needs to be heated by more than 5? F.

A device for securing a discharge end of a gas discharge apparatus inside a gas delivery conduit of a fluid impermeable liner covering a liquid-receiving basin features a first portion configured to be supported on the basin so as to engage an outer face of the liner which normally engages the basin and a second portion of the device configured to be movable relative to the first portion to selectively engage an inner face of the liner in opposite relation to the first portion in a working position. The inner face of the liner delimits the interior of the liner-covered basin. The first and second portions are configured to cooperatively form a generally tubular cavity substantially encompassing the gas delivery conduit in the working position, to clamp the gas delivery conduit over the discharge end of the gas discharge apparatus to substantially form a fluidic seal therebetween.

This disclosure relates generally to jets for spas and, more specifically, to jets that can be adjusted laterally along a width of the proximal end of the jet housing. The angular adjustment of the proximal outlet of the jet may be at least 30?. In some embodiments, the jet assembly includes a housing with a distal inlet at a distal end of the housing and a proximal outlet at a proximal end of the housing, the proximal outlet laterally adjustable along a width of the proximal end of the housing, with the proximal outlet maintaining a constant depth with respect to the proximal end of the housing as the proximal outlet is laterally adjusted along the width of the proximal end of the housing.

An inflation system, a massage pool air supply system, and an inflation method. The inflation system includes: a first gas channel (20) and a second gas channel (30); the first gas channel (20) has a gas inlet port and a gas outlet port; the gas inlet port is used for being connected to a gas supply apparatus (10), and the gas outlet port is used for communicating with a gas chamber (51) of the inflated object (50); the first gas channel (20) can be switched between a first state and a second state; the second gas channel (30) is arranged in parallel to the first gas channel (20); the second gas channel (30) is used for communicating with the gas chamber (51); a gas pressure sensor (40) is provided on the second gas channel (30); in the first state, a gas pressure in the gas chamber (51) measured by the gas pressure sensor (40) does not reach a set value, and the first gas channel (20) can inflate the gas chamber (51); in the second state, the gas pressure in the gas chamber (51) measured by the gas pressure sensor (40) reaches the set value, and the first gas channel (20) can stop inflating the gas chamber (51). The inflation system can prevent over inflation and can effectively protect the inflated object.

An air pump for dispensing air massage therapy to a basin is provided. It may be used and with a disposal liner. The air pump includes a motor, an air generator, a mounting housing member, a gasket or seal, and an air nozzle. The air pump assembly includes the air pump and the air dispenser. The air pump preferably also includes a printed circuit board (PCB), a PCB cover, an LED light, an infrared light, and a contactless fluid sensor. The present invention is also directed to a pump apparatus that includes an air pump as described, a power source, and/or a control apparatus.
