Performed work as proposed. The customer had a leaking 40 gallon water heater and needed it replaced with a 50 gallon water heater. The customer also needed to have about 10 feet of venting replaced. I removed the existing water heater and pan. I cleaned the area of installation. I also removed the corroded venting. Performed installation of the new venting, new water heater and new water heater pan. I used the existing drain line for the pan. I also installed a new water heater water shut off valve for the customer. The new water heater was installed with a new gas flex, sediment trap, water heater supplies and earthquake straps. I filled the water heater and turned on the heat. I set the water heater temperature to 120 degrees as per customer’s request. I checked for water leaks and also tested for gas and carbon monoxide leaks with electric detectors with the customer. The water heater performed as designed and there were no water, gas or carbon monoxide leaks when last checked. The
