A plumber installed a bleeder port in our upstairs bathroom and a valve to feed the frost=free facet downstairs in the garage. He never told us how the system works? The bleeder was left open and our downstairs is flooded out. The plumber created the problem because a bleeder-port isn't needed when you have a frost-free facet.
We wonder if the plumber is required to make up a plan, or specifications, and outline the project, so that inspectors and the homeowner can see if he did was what proposed? We had a contractor come in to do our heating, it's a disaster, and we got the specs and learned he didn't do anything at all as required.
