Client has us back out today because there is a leak on the closed water system, there is water pooling in the garage ams he is unsure where it’s coming from. There is also water damage on the inside of the home from the same leak. I was able to find that the leak is coming from the cold connection on the washing machine box, the shut off valve for the cold side is also leaking. Today we replaced the washing machine box, water is back ok with no leaks.
