Call for leak in ceiling in dining room. George stated that the leak has occurred sporadically over a year. He also stated that he has used small auger or retrieval tool to remove blockages from this shower in the past when it was draining slowly, including recently. After he removed hair the ceiling stopped dripping. When I inspected the master shower I found that the waste line and tile shower line are in poor shape. It appears that the seal between the shower and waste line is bad. Due to the nature and condition of the shower pan and tile, it will likely need a new shower pan. Today repairs were declined, and George wanted an opinion on what would cause this type of damage in order for them to decide which route to take for repairs and replacement.
