After arrival I began my plumbing up and I explained to the homeowner the process of what today's job entailed. I started off looking at all the restrooms as well as the kitchen downstairs and noticed that everything has been replaced in the past couple years and the master bathroom was recently remodeled. The only thing I noticed was in all of the restrooms and the kitchen was that one of the P-traps in the downstairs bathroom had a surplus amount of pipe dough on it. I then went into the garage where the water heater is located and noticed that the vent was starting to rust and the emergency shut off valve was completely covered in hard water residue and is almost to the leaking stage.
