Cross connection behind washer?

Author: Squunk (OH)

I'm looking for some help regarding a cross connection I found behind a friend's washing machine. There are 1/2" copper hot and cold water lines that come down to the hose connections. Then each line continues down for about another 6". At that point there is a smaller diameter (3/8"?) loop of about 2 feet of flexible copper line that connects the hot water line to the cold. Obviously this is not a mistake - somebody went to a lot of work to add this cross connection. Can anyone explain to me why this was done?
I don't know if it's a coincidence or not, but I also noticed that the hot water hose was connected to COLD on the washing machine, and the cold water is connected to HOT. Any ideas?

Author: hj (AZ) Absolutely no idea. The hot and cold lines could be reversed which would be why the hoses are "crossed".

Author: hj (AZ) their own version of a Grundfos "Comfort" system, but without a check valve in the bypass. I have done the same thing, but used an A/C 3/8" check valve between the hot and cold.
