At the end of my last column I said that this chapter would deal with an important step forward; the bladder tank. I will write about that farther along in this version but I forgot one unique and not super popular method of providing air separation.
In this method, in place of a rubber or Styrofoam disc, the manufacturer provided the installer with a product called “stars.” Now these so-called stars looked something like a miniature space ship. The middle was a round or semi round piece of, I think, polyethylene or some other floating plastic and the top and bottom had some supports in a cross pattern. I believe the center round part was small enough to go through a 1-inch pipe.
