Today we showed up for a complimentary water heater flush. Upon arrival there has been nothing wrong with the water heater or the water heater is the properly 3 years old. We flushed the tank one time filled it back up, then flushed it again and filled it the back up. We turn the power back on to the water heater, and it is working as should be They had a question about a sprinkler head that got ran over, I told him to contact the irrigation company about that repair. Thank you for choosing comfort expert!
