Televised sewer from clean outs outside in backyard and in front near sidewalk. Sewer has roots at several area and also has heavy sludge between clean outs. Downstream clean out is a combination clean out / check valve and we believe that is the reason for the sludge buildup. Water leaking on the floor appears like it may be coming from a crack on a tee above ground that was visible through the cleanout in the garage. Will provide proposal for lining clay to prevent roots.
