Arrived on site client state that they had a kitchen clog. Upon inspection in the garage thier were a few leaks coming from the kitchen drain. One leak was coming from a galvanized connection where the nipple just fell apart and was corroded. Attempted to snake the galvanized line but was unsuccessful. Told client that we should cut this section of piping out and in order to do so we need to use the chipping gun to remove some of the brick and pull the pipe out of the wall. We will return another day to perform work.
