I was called to a home to check the wiring and flush the water tank. Upon arrival, I checked the wiring and found no issues. I then flushed the water tank and checked the element, which was working fine. I made sure to test all the faucets and showers to ensure they were working properly. I also checked the pressure and temperature of the water to ensure it was within the acceptable range. Finally, I made sure to clean up any debris that may have been left behind and left the customer satisfied with the service.
