Upon arrival to the home I explained to the homeowner and I was here to flush his water heater because it is part of the membership plan me and Customer also talked about some settling in the backyard where the septic tank was installed. I began shutting the gas off to the heater and then draining it and flushing it out properly. Once I was done flushing the water heater I filled it back up with water and light the pilot light for the heater and then turn the heat back on to the heater and made sure that it was heating properly. I then proceeded to go into the house and bleed all of the air out of the lines. We will be able to send somebody out next week to adding dirt to the settled areas.
