Upon arrival, customer informed me that he was looking to replace his hot water heater because he’s going to put the house up for sale and insurance is going to recommend that he changed the heater. The heater is currently 17 years old. Customer identified a 30 amp breaker which is sufficient for the size hot water heater he has. All of the piping associated with the hot water heater and the electrical are up to code. Customer will be doing the heater changed with no permit. Customer fully understands the difference And liability. I prepared an estimate for the customer for 50 gallon heater and sent it to his email. I advised customer all he has to do to move forward is open the email and sign the estimate and dispatch will get me scheduled according to his availability. Customer was very satisfied with the estimate And said he would like to get this done by next week. Customer said he wanted to look it over, but most likely he will be using John the plumber.
