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 massage pillow configured to be positioned over a fluid jet includes a cushion and a retaining assembly. The cushion includes a front surface, a rear surface, and side surfaces extending there between. The rear surface includes an annular edge defining an opening providing access to an interior of the cushion sized to at least partially cover the jet. The retainer assembly includes an opening configured to align with the jet and a peripheral edge configured to retain the annular edge of the cushion. The retainer assembly is configured to be removably fixed to a wall surrounding the jet with the jet aligned with the opening of the retainer assembly and the opening of the cushion, such that fluid expelled from the jet passes into the interior of the cushion, so that the pillow provides massage and/or warmth due to the expelled fluid.

A pumping system and method including a flow locking feature. A pump controller includes a user interface configured to initially receive and set a plurality of programmed flow rate settings, a maximum locked flow rate, and a minimum locked flow rate. The pump controller is also configured to disable resetting of the maximum flow rate and the minimum flow rate once they are initially received and set and to allow resetting of the plurality of programmed flow rate settings throughout operation of the pumping system. The pump controller is further configured to operate a pump motor in order to maintain a first flow rate set by one of the plurality of programmed flow rate settings as long as the first flow rate is between the minimum locked flow rate and the maximum locked flow rate.

A foot spa includes a body and an electrolysis device. The body has a receiving space for containing water. The electrolysis device is mounted on a bottom of the body and includes a case, a control module and two electrolyte plates. The control module is mounted inside the body. The two electrolyte plates are mounted on a top portion of the case and are electrically connected to the control module. When the foot spa is operated, salt water is added to the receiving space for the two electrolyte plates to be soaked into the salt water in generation of an electrolytic reaction, such that sodium hydroxide and hypochlorous acid can be generated from the salt water to sterilize and deodorize the feet of users and provide the hygienic advantage.

A water valve and a pool are provided. The water valve includes a valve body having a first channel; and a valve plate having a valve plate opening and configured to control opening or closing of the first channel by sliding; when the valve plate is in a first position, the valve plate opening is aligned with the first channel and water can flow through the first channel, the water valve is opened; when the valve plate is in a second position, the first channel is blocked by the valve plate, the water valve is closed. The pool includes a water inlet part connected with a pool wall and the water valve detachably connected with the water inlet part. The water valve is simple in operation, has good sealing performance and switch function of the water valve and disinfection function of the chemical dispenser, thereby improving the water valve's performance.

Embodiments of the present disclosure provide systems and methods for a pool hub. The pool hub may include a primary electrical system, a pump, a secondary electrical system that receives power from the primary electrical system; a converter; and an electrical outlet that receives power from the secondary electrical system; where the converter distributes power from the primary electrical system to the secondary electrical system. A number of sensors and/or devices associated with a pool may be powered via the secondary electrical system.
