As a part of routine maintenance and testing, one must ensure that eye wash stations have access to clean water that flows appropriately and at the proper water pressure. Testing appropriate water flow and water pressure is messy. The inspection splash guards of the instant invention minimize water from splashing outside a wash basin area and are transparent to ensure proper visualization during eye wash station maintenance and testing.

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.

A method for treating water in a spa or a hot tub includes, for example, suspending a water treatment dispenser from an upper end of a filter cartridge disposed in a skimmer of the spa or the hot tub. The dispenser includes a water treatment material. A supply of water is passed from the spa or the hot tub into the skimmer and through the filter cartridge so that the dispenser suspended in the filtered water in the filter cartridge is operable to dispense the water treatment material from the dispenser, and a supply of treated filtered water from the filter cartridge is returned to the spa or the hot tub. A cover, for example, may be employed when the dispenser is not used.

A fluid pump assembly is provided. The pump has a pair of units magnetically coupled to each other. The first unit contains a drive motor and a magnetic assembly. The second unit contains a magnetic assembly and a blade of a propeller/impeller for imparting movement to a fluid. As the first unit is activated by the drive motor, a magnetic flux is created which in turn rotates the magnetic assembly in the second unit, driving the blade.

A walk-in bath comprising a sidewall and a door; wherein the door is configured to be in an open position or a closed position, the sidewall and closed door define a tub configured to hold bathing water, the door comprises a fin configured to be grasped by a bather, and the fin comprises a continuous projection positioned on a top edge of the door between a first end of the door and a second end of the door.

A leg care apparatus includes a main body configured to provide an action space in which a leg is accommodated, a bottom module which is placed on a bottom surface of the main body and in which a component for a foot bath is accommodated, and an action space adjustment module configured to adjust a size of the action space.

A control box of a massage pool is provided and includes: a filtering water pump unit, including a filtering pump body, a filtering water inlet pipe connected between the massage pool and the filtering pump body, and a filtering output pipe. The control box further includes a massage pump unit, including a massage pump body, a massage inlet pipe connected between the massage pool and the massage pump body, and a massage output pipe. The control box further includes a water outlet pipe configured to output water to the massage pool, and a three- way connecting pipe fitting. The three-way connecting pipe fitting includes: a first branch pipe having a distal end connected to the filtering output pipe, a second branch pipe having a distal end connected to the massage output pipe, and a third branch pipe having a distal end connected to the water outlet pipe At least one valve is configured to alternately open and close a first flow path from the filtering output pipe through the first branch pipe.
