Dual-chamber water jet assembly for in-ground pools or spas

Abstract

A water jet assembly for in-ground pools or spas that includes a first chamber with a water inlet and a second chamber with an air inlet and a water outlet. Water and air flow from the respective inlets to the water outlet such that a water-jet effect is achieved.

1 . A combination in-ground spa or pool and water jet, comprising: 
 an in-ground spa or pool made at least partially from cementitious material; and    a water jet assembly that includes a first chamber having a water inlet, a second chamber having an air inlet and a water outlet, and an interface between said first and second chambers through which water flows,    wherein the in-ground spa or pool contacts at least a portion of said water jet assembly.    
   
   
       2 . The combination of  claim 1 , wherein water flows hoselessly from said water inlet to and out of said water outlet into said in-ground spa or pool.  
   
   
       3 . The combination of  claim 1 , wherein said water outlet further includes a water-jet fitting disposed thereon.  
   
   
       4 . The combination of  claim 1 , wherein said interface comprises an opening between said first and second chambers, said opening having a diameter of less than one half inch.  
   
   
       5 . The combination of  claim 1 , wherein said interface comprises a pipe between said first and second chambers, said pipe having a diameter of less than one half inch.  
   
   
       6 . The combination of  claim 1 , wherein said cementitious material comprises gunite.  
   
   
       7 . The combination of  claim 1 , wherein said water jet assembly is inset into a wall of said in-ground spa or pool such that at least a portion of said assembly is contacted by said cementitious material.  
   
   
       8 . A method for constructing a water jet assembly for an in-ground spa or pool made with cementitious material, comprising the steps of: 
 (a) providing a water jet assembly that includes a first chamber having a water inlet, a second chamber having an air inlet and a water outlet, and an interface between said first and second chambers through which water flows; and    (b) installing said water jet assembly in said in-ground spa or pool such that the in-ground spa or pool contacts at least a portion of said water jet assembly.    
   
   
       9 . The method of  claim 8 , wherein step (a) further includes the step of providing hoseless water flow from said water inlet to and out of said water outlet into said in-ground spa or pool.  
   
   
       10 . The method of  claim 8 , further including the step of providing a water-jet fitting upon said water outlet.  
   
   
       11 . The method of  claim 8 , wherein said cementitious material comprises gunite.  
   
   
       12 . The method of  claim 8 , wherein step (a) further comprises providing at the interface an opening between said first and second chambers, wherein said opening has a diameter of less than one half inch.  
   
   
       13 . The method of  claim 8 , wherein step (a) further comprises providing at the interface a pipe between said first and second chambers, wherein said pipe has a diameter of less than one half inch.  
   
   
       14 . A combination in-ground spa or pool and water jet, comprising: 
 an in-ground spa or pool made at least partially from cementitious material;    a water jet assembly that includes a first chamber having a water inlet, a second chamber having an air inlet and a plurality of water outlets, and an interface between said first and second chambers through which water flows,    wherein the in-ground spa or pool contacts at least a portion of said water jet assembly.    
   
   
       15 . The combination of  claim 14 , wherein water flows hoselessly from said water inlet to and out of said plurality of water outlets into said in-ground spa or pool.  
   
   
       16 . The combination of  claim 14 , wherein said plurality of water outlets further include a water-jet fitting disposed thereon.  
   
   
       17 . The combination of  claim 14 , wherein said interface comprises a plurality of openings between said first and second chambers, said openings having a diameter of less than one half inch.  
   
   
       18 . The combination of  claim 14 , wherein said interface comprises a plurality of pipes between said first and second chambers, said pipes having a diameter of less than one half inch.  
   
   
       19 . The combination of  claim 14 , wherein said water jet assembly is inset into a wall of said in-ground spa or pool such that at least a portion of said assembly is contacted by said cementitious material.  
   
   
       20 . The combination of  claim 14 , wherein said first and second chambers are joined along a common panel and said interface is disposed through said common panel.
