my home was build in 2007, and it was 1st one on the block, all my neighbors home were build in 2012+. so i would think sewer system would be new. not sure if neighbor hood build in 2010+ has backflow preventer or not.I
Question for you, you mentioned many of your home systems, but did you failed to mention the situation and age with your sewer latteral and sewer main line. Also do you have a sewer backflow preventer?
