Abstract: A filter system includes a conduit for fluidly interfacing to a pump and a shroud adapted to be in fluid communication with a body of water in a spa/tub. A stand pipe has a first end structurally affixed to a bottom surface of the shroud. The first end of the stand pipe is fluidly interfaced to the conduit for transference of water to a pump. A distal second end of the stand pipe has a bypass valve and the stand pipe is sized and positioned within the shroud for holding and supporting a filter media.

Abstract: An accessory for installation in an orifice of a wall of a molded product has a base portion that has an interface area. The orifice of the molded product has side(s) protruding into the molded product inwardly away from the wall of the molded product. A cross-sectional shape of the interface area is substantially the same as a cross sectional shape of the orifice. The cross-sectional dimensions of the interface area is substantially the same as the cross-sectional dimension of the orifice, thereby the interface area of the base portion fits into the orifice (either loosely or tightly fitting). There is at least one seat circumscribing the interface area and each seat contains a closed-loop elastomer seal. A feature portion (e.g. a spa-jet face) interfaces to the base portion and the feature portion holds the interface area within the orifice.

Abstract: A method and apparatus for forming a tubular orifice formed/added to a wall of a molded product such as a tub, spa, hot tub, boat hull, tank, vat, trough, etc. The resulting tubular orifice has a smooth, regular, tubular inner wall that seals well with accessories that have tubular interface sections that fit within the tubular orifice and seal using one or more o-rings. The orifice is formed around an insert that is removably held to an inside wall of a mold by, for example, magnets during rotational molding, thereby enabling extraction of the molded product from the mold as the inserts separate from the inside wall as the molded product is extracted.

Abstract: A spa/tub jet is disclosed including a jet base portion and a face portion and having a channel extending through the jet base portion and through the face portion at a fluid exit. A plurality of side-directed fluid orifices is included. Each of the side-directed fluid orifices is in fluid communications with the channel. To reduce pain to a user who moves their body too close to the spa/tub jet, as the user's body impedes a flow of water out of the fluid exit orifice, water pressure is directed out of the side-directed fluid orifices.

Abstract: A system for removably connecting plumbing to a device includes a flange, one end of which is configured to bond to the plumbing. An insertion area at a distal end of the flange is sized and shaped to fit within a port of the device. An o-ring seat is cut/formed across a perimeter (e.g. outer circumference) of the insertion area of the flange. An o-ring is positioned around/in the o-ring seat such that, after insertion of the insertion area of the flange into the port, the o-ring provides a seal between the insertion area and an inner surface of the port. A retention device such as a retention nut holds the insertion area within the port.
