I am working on a sweetwater spa and located a broken jet as the source of its leak. I dug back to the jet thru all the foam, revealing the broken housing (I'ld guess to say that it froze). I removed the innner parts from the inside down to the part that goes thru the shell, and the part # on the face of it is H.A.I. 38-0001. However, I can not find that part number in any of my parts books. I do not have a book for Sweetwater spas, just ones like Horizon, ect. I even went to Hydro Air Industies website and cant find such a number. SO where can I find out what jet is supposed to go in there?? I realize I can get a jet from horizon that will work, but I was not even able to remove the old jet, as I didnt have my dremel cut-off tool or a sawzall with me. The jet would not turn out with a pair of 18" channel locks, so I'm thinking it has a nut on the back side of it, and thats where my dremel would come in. (no room for 18" channel locks on the back side with all that dang foam in the way.) can any one shed some light on this for me??

Thanks,
