get your mind out of the toilet ;)
I found a plumber! My toilet is now up and flushing. It turns out I needed a flushometer valve. I thought it sounded made up, like The Flux Capacitor in Back to the Future, but I looked it up and it is indeed legit.
Definition: A device that discharges a predetermined quantity of water to fixtures for flushing purposes and is closed by direct water pressures. (dictionary.com)
But I ended up being over two hours late for work. The guy was supposed to be here at 8:30 am, arrived at 9:30, left to pick up a part and was not back till 10:20. urghh!
And why is it that when you are late your boss always seems to be right near the front entrance and the VP near your desk as you enter and remove your coat?
