摘要： Devices and methods for sewer system cleanouts such as provide increased cross bore safeguard during sewer system cleanouts. A sewer system cleanout safety device includes a housing for placement at a sewer cleanout opening to prevent passage of gas out through the sewer cleanout opening during the sewer system cleanout. The housing includes opposed inner and outer cleanout opening surfaces, and a peripheral surface extending between said inner and outer cleanout opening surfaces. The housing includes a cavity extending between the inner and outer cleanout opening surfaces to permit passage of a sewer system cleanout implement therethrough. The housing further includes a cavity lining surface to seal with the sewer system cleanout implement passing therethrough.
