I have a whirlpool tub in my master bath that has an issue with two jets. They are old stainless steel jets that are held between a plastic bushing front and back. Two of them have both bushings in the front, and the jet won't stay where you place it. It just bounces around. There was only one that was messed up, and I was trying to learn how to fix it from another one, and I messed it up. Does anybody know how to reseat these things?
