I have two Maddock toilets in my home both are stamped and are called a “Durock.” Where the tank attaches to the pipe to the bowl is a flange with the flapper and pipe that extends upward. The flapper hinges on this pipe. My problem is that the pipe has corroded off the cast flange. Any suggestions on repair or purchasing necessary parts? J
If you are talking about the flapper in the tank try one of thse that fit over the pipe. Art retired plbg Go to http://www.google.com and put name in to search.
