For the job, I worked on flushing out 250 gallon water heater tanks in the guest bedroom bathroom in the basement. There is a small utility closet that holds both 50 gallon water heaters that we had installed back in 2022 had to flush the first one which is the one on the left and then the second one on the right Flush both tanks out. So that they were completely empty I did a shake test on the one on the left to indicating that it is empty however, I wasn’t able to move it that much due to the fact the way that they are currently piped together the water pressure on the home is normal. It is at 55 psi. After the flush of both water heaters, I made sure to turn the breakers back on after the water heaters filled up all the way, indicating that there would be no issues with the thermostat or elements burning out once complete. There are no leaks of any kind CUSTOMER should get hot water anywhere from 45 to an hour after leaving.
