Folkes arrived on 12/8/2021 to install a new 80gal system 2000 water heater. Upon arrival I turned the water off to the old unit and isolated from the boiler. I then drained the old heater all the way down and began to pipe in the new one in. I started by piping in the cold side and the hot side of the unit and then piped in the boiler connection. After everything was secured I began to fill the new unit and I let all the air out through the kitchen faucet. After the unit was full of water and had no air I opened up all the valves that where closed and connect the power to the system 2000. I waited until the water began to get hot and thanked the customer for choosing folkes and left. The office will take care of payment.
