For the annual maintenance check for this customer, we flushed the water heater and we also did a scope of the sewer line set the water heater back to the correct temperature once it was flushed out properly drained did a full sewer scope of the entire line, didn’t notice any bellies or cracks or roots in the line went all the way down to the county line about 90 feet video is uploaded. I recommend getting the shower valve in the master bathroom replaced, just due to the condition of it however it is not necessary at this time. Also the master bathroom P-trap is an S trap and I recommend getting that replaced as well to bring it up to code compliance.
