Someone ask why I left so abruptly last night. Wife was screaming from the garage. The hot water pipe between the boiler and hot water heater had burst. I had to leave to go fix it.
Seems the neighbor got a new garage door opener. He got a Sears 1/2 hp just like mine. He randomly set his code, and just happened to set the same as my code. When his wife came home yesterday she pushed the button as she passed my house. My garage door opened and I did not know it. When she went inside her garage and closed the door she was far enough not to close my door. It was 10 below yesterday and the pipes behind the hot water heater that are against the back wall froze. When I found the door open I checked for frozen pipes, but did not find the one leaking behind the heater. They were still froze at that time and not leaking. When they thawed, it was a mess.
To make repairs I needed two 1/2" couplings, and I only had one. So off to the hardware store I went. Got there after they had closed but the manager let me have what I needed. She had already closed down her registers, and they were on a security system where they could not be opened till morning. I went back this morning and paid for the items. Nice to live in a small town where everyone knows you.
