. Can I use any of them as a "generic" replacement? I'm guessing this part is called a "water-inlet injector". Here's my best description of it: it's a hard plastic part with a wide "head" or "cap" that stays inside the tub and a thin long cylinder "body" that sticks out of the tub where it's connected to a silicon flexible tube. The head broke off thus the tube is leaking. I found a related thread
though I'm not sure I need all those parts (nozzle, injector valve, sleeve).
