So we got our new water heater installed by about 6pm last night. There were a few hiccups in the installation process like having to add more pipe, moving the water heater location 2 feet to the right, and adding a drip pan. But the guys did a fast and beautiful job, and we have ample hot water now.
Unfortunately we discovered a new problem after they left. Rich had turned off the hot water to the kitchen sink yesterday afternoon, so we'd have at least one sink we could use. Apparently these valves have not been turned in quite some time, if ever. So turning the hot water off actually broke the valve. So now we can't use our kitchen sink until we replace the valve underneath. And this probably won't happen until tomorrow morning.
In the meantime, I think we'll be washing dishes in the bathtub tonight.
