Abstract: A self-cleaning water filtration system includes a pre-filter to filter oils and relatively medium sized particles in a water flow, a multi-stage filter to purify and provide a second level of filtration to the water flow, and a self-cleaning filter to provide a third level of filtration to the water flow. Water flow through the filter media of the self-cleaning filter is redirected to flush waste to a containment-tank filter. The self-cleaning filter has a purge output, which may spray the pre-filter to substantially remove particles from the pre-filter for collection in the containment tank. The multi-stage filter may have at least two layers of filter media. The pre-filter may be disposable and comprised of a mineral sanitizer positioned between two layers of an oil absorbing fabric.

Abstract: This invention relates to a method for mounting micro jets on whirlpool bath surfaces. Micro jets are mounted in the bottom of cups. The cup containing the micro jet is mounted in an opening performed in the whirlpool bath shell. The proposed method is specially interesting for jets located on surfaces where fluid flows are obstructed such as the surface where a person's back rests when someone lies in a whirlpool bath. This method allows manufacturers to install micro jets those whirlpool bath surfaces without having a recessed part. Moreover, it allows to modify easily the fluid jet pattern depending on the consumer's needs. The present invention also concerns recessed micro jets for whirlpool baths and method for mounting the same.

The multi-stage filter may have at least two layers of filter media. The pre-filter may be disposable and comprised of a mineral sanitizer positioned between two layers of an oil absorbing fabric. The water flow through the filter media of the self-cleaning filter may be redirected in response to an occurrence of either a change in output water pressure or an indication from a timer occurring on a regular basis.

Abstract: The whirlpool tub includes a rigid tub shell inserted into the opening of a surrounding podium. The tub is to be filled with hot water. A first insulation membrane is installed spacedly around the tub inside the podium, defining a first closed air pocket between the tub and this first insulation membrane. A second insulation membrane is installed spacedly around the first insulation membrane, also inside the podium, defining a second closed air pocket between the first and the second membranes. The first membrane is punctured and hangs loosely from the podium structure, thus allowing limited air circulation between the first and second air pockets. Consequently, positive condensation control is accomplished, preventing same from occurring, in addition to providing thermal and acoustic insulation to the tub. The first membrane comprises an inner reflective metallic foil fixedly mounted on a synthetic felt backing. The second membrane is a mineral wool blanket.

Abstract: The bracket is to be installed to the inner face of the peripheral rim of a bathtub, to attach the latter to the inner peripheral edge portion of a fixed casing. The bracket has a rigid head portion which is fixedly attached to the inner rim of the bathtub, and a downwardly depending arcuate resilient foot which carries at its lower end a foot. When installing the bathtub inside the casing and more particularly inside the casing peripheral edge portion, the tub is downwardly displaced until its rim comes into downward abutment against the casing peripheral edge portion, the bracket slidingly abutting against the casing peripheral edge portion with a corresponding resilient foot deformation, allowing the foot to slide under the casing peripheral edge portion and to snap itself thereunder for preventing vertical displacement of the bathtub relative to the casing peripheral edge portion. Indeed, the casing peripheral edge portion is then wedged between the bracket foot and the bathtub rim.
