We recently moved into a 10 year old home and purchased a new refrigerator with a water filter and ice maker, only to find that when we hooked it up to the single water line behind the fridge, it dispenses hot water. I don't think the line has been used before now and was wondering if anyone has ever heard of something like this where the line is attached to the water heater instead of the cold water line. What will need to be done to fix this?

Well folks, the Plumber/Scientists are shooting me down. Come on over to the HVACTalk forum where things really get hot. Bye.

Interesting post. I stumbled on this topic as I am about to put a fridge with a water line in the former location of a water heater, so both hot and cold lines are nearby. I was hoping to find a clearcut answer on which one to hook to. You all make good points, some I think more relevant than others.

I wanted to throw out another pointless fact. Hot water freezes more quickly than cold.

Can hot water freeze faster than cold water?

Given the ambient room temperature, this probably matters little, if any.

plumb guy,

The link is correct, I support cold and you can use the hot water connection too, in most states it is connected to the cold supply, so lets use the cold side let this post to rest and the case is closed, Thanks.
