I’ve watched the Doing it with Betty videos on making the bag and putting the whole assembly together but they seem to skip over how to make the pressure regulator that she has. Â I also have been researching for about a week on this and still haven’t found out how to make it. Â The tank I’m getting has the balloon valve on it (said I was needing it for a part, dumb me) so I don’t know how to get a different valve now. Â Any help?
