OK so the plumber left about 7:30 last night with the water heater installed. He said it would take about 2 hours to get the water heated. I'm thinking, ahhhh, long hot shower then to bed. At around 10, I turned on the faucet and NOTHING came out. So I called them this morning and they said, oh, it must be blockage from another pipe. It will require another repair. Does that even make any fucking sense? Suddenly and coincidently the water pipes are plugged as soon as this guy leaves? I am even more tired of talking about and thinking about water heaters than all of you are of hearing about it.
