Guest guest Posted October 6, 2011 Report Share Posted October 6, 2011 In Ed Leeper's book, it quotes the code as saying there must be a connection to a water pipe " if available " . His approach is to make the pipe not available by making it plastic or putting it behind a wall. Not clear all inspectors would buy this.
