After inspection of sewer main i found that customer already had several cleanouts located throughout property. There was a mainline clesnout in front yard that allowed access to both up stream under the home, as well as access all the way out to city sewer. There was also two cleanouts in back of the home on exterior wall. One servicing the laundry and the for the kitchen sink. Sewer main in front yard leading out to city sewer was in good condition with a large portion having already been replaced. While performing inspection from cleanout in backyard I found that there was large amounts of sludge and build up in the line servicing the laundry and kitchen sink drain leading to bathroom. This section needs to have hydrojetting and descaling performed to clear our sludge and prevent future clogs.
