A different technician with the same company came out today and asked if I was ready to get all the equipment out of here. I said "Yes!" As he began to remove the fans in the garage he yelled out, "Ma'am you have another leak." I headed to the garage and said, "Please tell me you're kidding." But he wasn't. The brand new extension tank (not the actual water heater, but a smaller tank off to the side that helps pressurize the hot water) was leaking. The technician put the fan back and scheduled a time to come back out tomorrow. I called the plumber and am now waiting for him to arrive and fix this new leak.
I'm ready for this to be over. But at least this time the water stayed in the garage and didn't come into the house.
