CUSTOMER STATED:**ANNUAL WHOLE HOME PLUMBING INSPECTION** TECHNICIAN NOTES: Upon inspection I found that there is a AO Smith 40 gallon natural gas water heater located in the Basment of home, and is 20 years of age which is well outside of manufacture warranty. I found that the thermal expansion tank is not only full of water, but is connected to the hot side antinode instead of the cold side which is out of state code regulations. I also found that there is a leak coming from the upstairs hallway guest bathroom, and is leaking from the cracked tile/grout around the tub. I let the h/o know that I would recommend replacing the existing water heater. I found that overall everything in the home is in good condition, and functioning properly. RESOLUTION/RECOMMENDATIONS: I strongly recommended to the h/o that she have the existing 20 year old natural gas water heater located on the basement of home replaced to help fix/prevent any future plumbing issues.
