A group of components which can be configured to achieve a variety of vertical sewer riser systems to protect against settlement and compaction forces.
Two key features include a deep socket bend that allows earth compaction and settlement to occur without pipe pulling out of the fitting socket as the installation settles, and the combination of the vertical riser adapter and controlled settlement joint that provides an extra measure of security in the event the connection begins spearing action before reaching 500 lbs/ft force.
