Upon arrival I found customer has a pin hole leak in their existing copper pipe right before it entered down into the unit. We previously replaced approximately 40’ of copper pipe on the roof up until where the shut off valve is seen in the photo. Due to the previous history of issues on this section of piping I recommend replacement of pipe from 90 located at the roof all the way down to where the pine ties into the circulating pump. This run is approximately 20’ in length. In order to perform replacement we will need to remove the water proofing located around the pipe to remove the old pipe and install the new pipe. We can attempt to add new sealant around protrusion through roof but recommend having customers roofing contractor come out and properly seal.
