Inspected a home yesterday, built in 2001, vacant, bank owned, had been winterized 8 months ago. They had someone come turn the water on and the electricity was on. Gas was turned off to the water heater and furnace, and the 15 amp breaker for the furnace was off. Temperature was 45 and supposed to go down to 30 or less here overnight, no warm up in sight. After looking everything over, I turned on the breaker, turned on the gas for the furnace, it fired up and ran fine. Turned on the gas to the water heater and lit it, ran fine. When I left I turned the gas water heater back off but left the furnace on at 50 degrees. Documented exactly what I did in the inspection report. Is this something I typically do ? Heck no. I've been told by everyone not to turn on gas or breakers, but under the right circumstances, I will. Will I get burned one day (figuratively meant), maybe. Was the calculated risk worth it to do a good inspection for my client? Well, my business, my choice.
