I was awakened today at 8am (I didn't need that sleep, really) by the plumber, who wanted to know if it would be okay for him to come install a new hot water heater right now. Still a little muddled from sleep, I eventually understood the situation and asked if 9 would be ok. Then I had to run around and take care of Nutmeg, then get over to the house to take a shower. (I have no clean clothes at the apartment! And if he was doing hot water work, I had to get the shower in before he got there....)
He showed up right at 9 and immediately got to work. The old pipes were so corroded from the copper-steel connection that he bent the steel one trying to separate them, so he ended up installing a longer-than-expected run of copper pipe. The removal of the old heater proceeded without ado, and someone from MSI came to deliver the new one---much taller---and it was put in place. He jackhammered out a brick and ran the 2" PVC pipe (I know, I know, but for HWH exhaust there actually isn't an alternative, as far as I can tell). Then he tried to turn the thing on, and while the fan started going, the heater part didn't. So he read the manual....
Turns out that since the last time he's installed a high-efficiency heater (recently, and otherwise the same model), they've switched to requiring 3" PVC. It detected the restricted airflow and wouldn't start. So then he sawed out the old PVC, went back and got 3", carved out a bit more brick, and reinstalled the exhaust pipe. And it worked! I now have a totally useless chimney.
Plan for tomorrow: cable guy installs cable and internet; water works does something to my meter; and I call the roof guys to make an appointment for that.
