Last month I had to have a plumber come out to my rental to fix a dripping faucet and shower head, and to check on a leak into the unit below mine. He came and replaced the moen cartridge, but put it in wrong, reversing the hot and cold. He came back out to fix it and to check on the leak which had become worse than before. (the downstairs resident wasnt home the first time for him to check on it) After he reinstalled the moen cartridge, the leak stopped. So here is the question (enough with the run on sentences!!)… would the moen cartridge that was installed wrong have anything to do with the leak that miraculously stopped?
Thanks for the input,
