Upon arrival customer had a scheduled job for a main water shut off and water heater to be replaced. We were able to remove old water heater, access the existing main valve and replace old style gate valve with a new 1/4 turn ball valve. We then installed pan buy tying in existing drain to pan. After pan was installed we installed new 55 gallon tanked heater, added an electrical switch, and corrected t/p relief line. Customer was very satisfied with our work. Existing water heater was not causing any damage to unit, it was just over 15 years old and needed to be updated. Thank you for calling John The Plumber -Shane
