It was very simple.  I had a problem with what you installed, you refused to come back and fix it and now that you have been \"caught\" you are telling lies to try and make yourself look better.\nYou are correct about only one thing, I DO NOT WANT YOU IN MY HOUSE AGAIN!  Someone who does substandard work, lies, cheats and steals is not welcome in my house.\nAs an update, I called another plumber, had them come to my house, tighten the connections and there have been no further leaks.  It would have been much easier for you to stand behind your work than to create all this...
