Geez, one thing after another! What a mess! I hope that you can find a good (and inexpensive) plumber to fix the leak & that your tooth FINALLY starts feeling better!! You deserve only good things coming your way! Just a thought, but is it possible that there is something going on other than an infection (since the antibiotics haven't helped yet)? That would just give us all one more bone to pick with this dentist of yours. I don't know what can go wrong with a root canal, but one would have expected the antibiotics to have started making you feel better by now.
Oh, and this might cheer you up a little: You're not the only one with leaking pipes! I FLOODED an entire laboratory yesterday because of a leak in the pipeline of the water used to cool a machine that I was working on. The machine was warming up & I was working on another machine, listening to an audiobook & the loud noises made by the machine I was focused on, and I didn't hear the pipe break free. In less than five minutes, half of the lab was flooded with an inch of water in places! It happened so fast, and I caught it soon after it happened, but still... Fortunately, it was just a huge mess & nothing was damaged. It could have been so
much worse. This laboratory happens to be is a special facility that contains multiple pieces of very sensitive equipment worth over $100,000. Even though all of the equipment has been donated to the school (and most of it is 20+ years old), it still costs a pretty penny every time something minor
goes wrong. I was very lucky.
And that's not the worst flooding story either! I've flooded one of the facilities rooms several times when I left the room & forgot that I had the distilled water machine running (it takes FOREVER to fill the big containers, so I'd go away for 10 minutes, come back & check, etc, etc). Now I know better. Those two floods were very minor, though. However, several years ago, one of my professors did the same thing. Only he completely forgot about
the water & left for the night. By the time someone found it, water had flooded the hallway & was pouring down the elevator shaft! And this was the professor's first week on the job! Not a good first impression to make!
