The stuff coming out of the jetted tub in our new house is the stuff that nightmares are made of. I found tons of videos and how to’s on cleaning the tub and jets, but they all talk about closing the air induction valve if specified in the manual. I don’t know what an air induction valve is, or how to turn it on and off, or who manufactured this tub so I can find a manual. Google wasn’t a help for once, so I’m turning here to see if anybody has any advice.
