Dear Mr. Esposito, If you practice engineering long enough, you'll sooner or later get involved in a project which doesn't work, which can't work, no matter what. If it hasn't happened to you before, it may have happened to you now. I've been at the house in Virginia of my parents, now long deceased, replacing the pressure switch for the submersible pump, replacing the hot water tank which couldn't resist a pressure of more than 100 lbs/sq in. and replacing the faucet on the kitchen sink (which was designed by a demon). I've not had the opportunity to see the questionnaire which you complete for me, but my son read me your answers which I noted on a blank duplicate which I had brought with me. He also read to me your most recent invoice when it came in the mail. Quite apart from the fact that you neither signed nor stamped the questionnaire, your denial that you examined the entire system serves to impeach (undermine) the validity of most - and the most important of your answers. Furthermore, I don't follow the reasoning of many of your replies. I conclude that the completed questionnaire that you returned to me has no legal merits and that I should not make any use of it. I have paid you very generously, and at this juncture, I don't know who owes what to whom. I don't want to pay you $70 per hour to argue with you. If you are interested primarily in collecting fees, we should drop the matter now. If you are interested in the problem, interested in helping me with the problem, then I should be pleased, after I get back to Belmont on October 9, to come to Plymouth to go over the questionnaire with you, without charge, to see whether I can change some of the questions so that your answers would be more convincing to me. If, without charging me, you'd like to refresh your memory about the installation, https://picasaweb.google.com/ernstjmeyer?authkey=Gv1sRgCLyi6u3szp_aWQ will give you access to some pictures you haven't seen. Sincerely, Ernst J. Meyer
