Split level house. Lower level is half crawl and half living space. At times, water comes out of basement floor drain but only when a lot of water is being used. Crawl has only one visible sewer line and clean-out which serves the kitchen which is above the crawl. On the living side of basement is a half bath and the laundry room. The floors are all cement in this area. No sewer clean-outs are visible. Are they in the walls? Assuming the line out to the street is restricted a bit, I need to rod that. Can I rod through the basement drain or should I take off the basement toilet and rod there? Or might I only need to rod at the clean-out in the crawl thinking that that is the most direct route to the street? Thank you.
