A jet pump has an impeller with a magnet that can be rotated by a shaft having a magnetic drive plate and wherein the impeller and the magnetic drive plate are separated from one another by at least one solid wall surface. The impeller can be located in a pump housing having a base and a cover. The base can have a surface bearing so that the impeller can contact therewith and rotated against the surface of the surface bearing.

Methods and apparatus for washing systems, both industrial and residential. Some embodiments pertain to face washing systems that provide a gentle upward flow of water for washing a person's face, but which can be easily reconfigured to provide a downward flow of aerated water for washing of the user's hands. Other embodiments pertain to visual indicators to help a user in a dark environment in the use of an emergency eyewash system. Yet other embodiments pertain to eyewashing systems incorporating filters that are automatically flushed of debris. Still further embodiments pertain to emergency eyewashing systems in which a mixing chamber is located downstream of a thermostatically controlled valve to reduce the possibility of a hot temperature spike being provided to the eyewashing outlet apertures, which could be harmful to users.

Fluid therapy, for example including spray water at along a user's body, have been found to provide various advantages both as a medical therapeutic technique for treating various physical ailments as well as to improve comfort of a user generally. Embodiments provide therapeutic fluid apparatus(es) and methods of using said therapeutic fluid apparatus(es). One example therapeutic fluid apparatus includes fluid outlets at particular positions of the apparatus to enable spraying of a fluid drawn from the environment around the apparatus at particular points along a user. Some embodiment therapeutic fluid apparatus(es) are removable from the environment(s) from which they draw fluid for use, such that the therapeutic fluid apparatus(es) can be positioned within such environment(s) without permanently altering the environment and/or otherwise affixing the therapeutic fluid apparatus within the environment. Some such therapeutic fluid apparatus(es) are similarly constructed of lightweight materials to facilitate portability of the therapeutic fluid apparatus(es).

Spa systems may be used all year round and in colder weather provide an enjoyable experience for users through the cold ambient outdoor temperature and the heated water of the spa. However, failures in respect of the water circulating pump and/or heater of the spa system either mechanically, electrically or through overall power outages mean the water in the spa system and its pipework can easily freeze if ambient conditions are cold enough leading to cracks in the spa system or pipes and hence leaks when the water thaws requiring costly repair or replacement of components or entire systems. Accordingly, a freeze protection system is provided that uses a backup thermal management system discretely or in combination with other backup systems. These freeze protection systems offering backup when mechanical failures, electrical failures etc. arise by providing thermal input to the spa system through alternate thermal paths and providing alarms.

A spa is provided including a frame, a shell mounted to the frame defining a basin for holding water, at least one sensor for monitoring a spa component or water condition, a communications interface including a cellular transceiver, and a battery for providing power to the at least one sensor and to the communications interface when the spa is not connected to a power source. The spa also includes a controller in electrical communication with the at least one sensor and the communications interface. The controller is configured to, while the spa is not connected to the power source, receive information from the at least one sensor, process the received information, and cause the communications interface to wirelessly transmit the processed information to a remote source or central server.

A bath massage chair includes a pillow, a back support configured to support a torso of the user when the user is seated in the bath massage chair, and a seat coupled to the lower portion of the back support. The pillow includes a pillow massage system and a pillow heating element configured to heat the pillow. The back support includes an upper portion coupled to the pillow and a lower portion opposite the upper portion, a back massage system configured to massage the torso of the user, and a back heating element configured to heat the back support. The seat is configured to support a lower body of the user when the user is seated in the bath massage chair. The pillow massage system, pillow heating element, back massage system, and back heating element are operably coupled to a controller.

A spa has an insulated cabinet with an uninsulated shell disposed therein. A filter assembly is downstream of a water intake. A heater is downstream of the filter assembly and a pump is downstream of the heater. A diversion line is in fluid line connection with an outlet of the pump. An ozonizor is in fluid communication with the diversion line. The filter assembly is coupled to the diversion line. A data processing system is coupled to the heater, pump, a control panel and a temperature sensor, wherein the data processing system responsive to when the actual temperature of an amount of water in the shell is a magnitude in degrees below a set temperature 1) turns the heater off if it is on or does not turn the heater on if it is already off and 2) turns the pump on if it is off or if it is already running does not turn the pump off.

A whirlpool bathtub system includes a basin having a plurality of nozzles, a water feed line connected to the plurality of nozzles, an air feed line connected to the plurality of nozzles, a pump configured to circulate water to the basin through the water feed line, and a blower having an off condition and an on condition, the blower being configured to provide air to the basin through the air feed line. When the blower is in the off condition, the blower is configured to allow air to flow into the air feed line. When the blower is in the on condition, the blower is configured to increase the flow of air flowing into the air feed line.

A pool apparatus for users to do activities in the pool apparatus. The pool apparatus includes a pool main body, one or more than one reaction deices and a control circuit. The control circuit is connected to the reaction device and controls the reaction device according to a setting to increase additional functions of the pool apparatus. When the control circuit is connected to an external device via at least one wireless network, a user may use the external device to adjust the setting. The external device does not need to be paired with the control circuit in advance. Instead, the external device interacts with the control circuit via a protocol to access and adjust the setting.

A pool or spa system includes networked pool or spa devices that can be dynamically configured with network address by a controller. The controller can transmit a device discovery request on a network and can receive a discovery response from pool or spa devices that require a network address. The system determines and assigns the network addresses for the pool or spa devices based on unique device identifiers associated with the responding pool or spa devices. The network addresses assigned to the pool or spa device are transmitted to the pool or spa device to be used by the pool or spa devices to communicate with the controller over the network. The system can be used to discover and assign addresses to various types of pool or spa devices, such as pumps, underwater lights, chlorinators, water feature controllers, remote controllers, and/or other types of devices.
