Ice Maker Supply Line Leak

One of the most difficult problems "to find" during our weekly inspections is a leaking ice maker water supply line. Even though the water main had been turned OFF in a Stonebridge home, apparently the pool service people were periodically  turning the water main ON in order to maintain water levels and that's how the problem began. Because they're located behind the refrigerator it's impossible to discover this problem until the problem has advanced to the point where it becomes obvious with water on the floor or as was the case of this house a stain began to show on the wall on the opposite side of the refrigerator. The top right photo was taken behind the refrigerator and the bottom photo right was taken of the wall on the opposite side of the refrigerator which was how we discovered the problem.  Fortunately we found the problem shortly after it began to show and the rug was easily cleaned with no longlasting stain. To prevent this occurring again we turned OFF the supply line and in the future, the owner will have to turn it back ON when they arrive for the season and OFF when they leave.
