Spa jet replacement system and method for its use

Abstract

A spa jet replacement system uses a hollow tubular positioning sleeve having an opening located proximate a first end thereof. A spa jet is inserted into the first end of the sleeve and the sleeve is inserted into the nozzle system of a spa until the opening of the sleeve aligns with an air inlet of the nozzle system, thereby positioning the spa jet upstream of the air flow of the spa fluid system. The outside diameter of the sleeve approximates the pipe(s) of the nozzle into which the sleeve is inserted so that the sleeve is friction held in place after insertion. A longitudinal slit may be located on the sleeve for ease of insertion.

DESCRIPTION OF THE PREFERRED EMBODIMENT

(6) Referring now to the drawings, it is seen that the spa jet replacement system and method for its use of the present invention, generally denoted by reference numeral 10, is comprised of a positioning sleeve 12 that has a first end 14 and a second end 16. The positioning sleeve 12 is a plumbing pipe and is thus a hollow tubular member that may be made from PVC or similar material. As seen, an opening 18 is located proximate the first end 14 of the positioning sleeve 12. A slit 20 may run longitudinally along the positioning sleeve 12, between the first end 14 and the second end 16 thereof, and radially opposite the opening 18.

(7) As seen in the figures, a typical nozzle system 22 of a spa has a nozzle exit pipe 24 from which the water-air mixture exits into the body of the spa. The nozzle exit pipe 24 is connected to an air inlet 26 via an appropriate T-fitting 28, with the air inlet 26 being air flow connected to a source of blown air, typically via an air manifold system 30. The opposing end of the air inlet T-fitting 28 is connected to a source of pressurized water typically via a water manifold system 32. A spa jet 34 which has a body 36 with a first side 38 and a second side 40, an annular lip 42 located at the second side 40, and an orifice 44 extending between the first side 38 and the second side 40 acts as the fluid flow constrictor. The spa jet 34 is resident within the nozzle system 22 of the spa, located upstream of the air inlet 26, as seen, within the T-fitting of the water manifold system 32. The spa jet 34 is positioned such that annular lip 42 faces toward the source of pressurized water and away from the nozzle exit pipe 24.

(8) The positioning sleeve 12 is dimensioned so that its outside diameter approximates the inside diameter of the nozzle exit pipe 24 as well as the inside diameter of the connector pipe 46 that connects the T-fitting 28 to the water manifold system 32.

(9) In order to use the spa jet replacement system and method for its use 10 of the present invention, the old spa jet is removed from the nozzle system 22 in any appropriate fashion such as via the use of a hole saw and drill as previously described. Thereafter, the spa jet 34 is inserted into the first end 14 of the positioning sleeve 12 via its first side 38. The outer diameter of the annular lip 42 of the spa jet 34 is greater than the inside diameter of the positioning sleeve 12 so that the spa jet 34 cannot be completely inserted into the positioning sleeve 12. Once the spa jet 34 is inserted into the positioning sleeve 12 to its maximum extent, the first side 38 of the spa jet 34 either does not breach or barely aligns with the opening 18 of the positioning sleeve 12. Thereafter, the positioning sleeve 12 is inserted into the nozzle exit pipe 24 of the nozzle system 22 via the positioning sleeve's first end 14 with the opening 18 of the positioning sleeve 12 facing upwardly in the direction of the air inlet 26 of the nozzle system 22. The positioning sleeve 12 is pushed into the nozzle exit pipe 24 and eventually into the connector pipe 46 until the opening 18 of the positioning sleeve 12 aligns with the air inlet 26 of the nozzle system 22. The proper depth of insertion of the positioning sleeve 12 into the nozzle exit pipe 24 is premeasured and the positioning sleeve 12 is cut to its proper length prior to insertion. As the outside diameter of the positioning sleeve 12 approximates the inside diameter of the nozzle exit pipe 24 and connector pipe 46, once the positioning sleeve 12 is inserted in place, it is friction held therein. The positioning sleeve 12 can be helped being inserted into position via an appropriate tool such as a rubber mallet (not illustrated).

(10) If the positioning sleeve 12 has a slit 20, the slit 20 allows the positioning sleeve 12 to deform slightly during the insertion process, making the insertion process easier. As the positioning sleeve 12 is made from PVC or similar material, once the positioning sleeve 12 is in place, the positioning sleeve 12 resiliently springs back to size and helps bias the positioning sleeve 12 in place within the nozzle exit pipe 24 and the connector pipe 42.

(11) The spa jet 34 is now properly in place and the spa is once again ready for use.

(12) While the invention has been particularly shown and described with reference to an embodiment thereof, it will be appreciated by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention.
