A low profile spa jet having a structure allowing for the use of a jet housing for both threaded/nut and grommet installation, wherein the jet protrudes into the spa tub less than 0.5″. The low profile spa jet also can have a jet face/flange that is interchangeable between threaded and grommet jet bodies without changing the relationship to the spa wall, wherein the jet protrudes the same amount in the installed state for both styles of jet body. The low profile spa jet also can have a jet face/flange that is removable and/or interchangeable before and after the jet body and jet internal are installed in the spa.

A lane rope float having higher wave absorbing performance than before is provided. A lane rope float is one that is attached to a rope R via a tubular portion and divides lanes of a pool, and the lane rope float is characterized by: including a plurality of blades that protrude from a side surface of the tubular portion in parallel with the rope R, and a wall surface portion that is coupled to side end portions of the blades to cover the blades, in which in an outer end portion of the lane rope float from the center of the tubular portion to the wall surface portion, at least ½ of the range from the center of the tubular portion to the wall surface portion is formed along a vertical plane V2 perpendicular to the tubular portion.

Arrangements for mounting pool fittings and methods for mounting pool fittings, for example, return fittings, to pool walls are provided. The arrangements and methods facilitate the installation and maintenance of pool fittings by preventing the undesirable rotation of the fitting during installation or maintenance. Aspects of the invention are characterized by mounting plates having one or more projections or recesses that engage one or more projections or recesses on the pool fitting to restrict rotation of the fitting. Mounting plates having one or more restricting projections or recesses are also disclosed. Aspects of the invention are not limited to return fittings, but can be adapted for use with any structure mounted to a pool wall, for example, to an insulated pool wall.

A fountain apparatus may include a wall insert that can be threadably attached to a water inlet port in the wall of a pool. The wall insert may split water flow into two streams, one that passes through a jet nozzle ball and into the pool, and the other that flows into a reservoir that supplies water to a stream nozzle tip to form a water fountain. A water insert reservoir cap may be releasably engageable with the wall insert and include two fluid passageways, one corresponding to the flow path to the jet nozzle ball and the other corresponding to the reservoir and the flow path to the stream nozzle tip. A reservoir locking cap may be used to secure the wall insert reservoir cap to the wall insert. A jet nozzle cap may be used to secure the jet nozzle ball to the reservoir locking cap.

The present invention is directed to below grade fluid containment structures, which may include a foam floor and a foam wall extending upward from the floor, the foam wall being formed from foam panels and optionally a plurality of metal splines. A foam buttress is provided as part of or adjacent to the foam wall, for reducing pressure against an exterior face of the foam wall that would otherwise be exerted by the soil, in the absence of the foam buttress, which places a top portion of the soil at an angle of repose, to minimize inward pressure. A concrete footing can be provided below the foam wall, where the splines of the wall are vertically oriented in the foam wall, with a bottom of the splines anchored into the concrete footing. The interior surface of the pool or other structure can be coated with any desired finish coating.

A foldable, portable fabric children's wading pool for installation in the ground and which has improved stability characteristics is provided. The pool includes a base region with a generally circular sheet of water-resistant woven fabric with a thread denier of between 400 denier and 600 denier, a stabilizer region comprising one or more sections of woven fabric with a thread denier of between 200 denier and 400 denier, where the stabilizer region is affixed to the outer edge of the base region, and with a number of sand anchors affixed to the stabilizer region. The pool is set up by digging a hole in the ground and forming berms along the edges of the hole. Then, the pool is unfolded and positioned such that the waterproof fabric base is in the hole, and the sand anchor section extends downwardly and outwardly from the edge of the sand berm. Then, a weighting material is loaded onto the sand anchor section and the pool is filled with water, preferably using the waterproof bag that also serves as a storage and transport bag for the pool when folded.
