Home inspection
My main trade is a home inspector. Friday's house had a re-circ pump on the hot water tank. Instead of the usual setup with a return line, this pump was simply installed on the hot water output line. My main thought is that this is not going to work very well. It seems like it would just be pushing to a dead end instead of actually recirculating anything. Just looking for anyone who may have run across this before. I can't see how it would work. There were no check valves, so the other thought is that it would push hot water out of the cold water side, but I'm not even sure how that would happen. The pump was not in use, and the house was not occupied at the time of the inspection, so I was not able to check it out under normal use circumstances.
