One day, I told @Joe that it would be nice to add an upholstery tool trigger valve to one of his Wash Downer's. In typically Joe fashion He said: "If you want it, then do it!" So Joe sent me the parts and this is the result.
Works great! I can spin the jet for any spray orientation I want without busting out a wrench and I can swap out jets to get any flow or jet spray pattern I want.
