The stack-aerator is delivered with closed caps. After removing the caps, the required horizontal branches can be butt-welded directly to the stack-aerator. The horizontal branches can also be connected using plug-in sockets butt-welded to the stack-aerator. Plug-in sockets allow for easy assembly on-site and enable a transition from 110 mm dBlue for acoustic horizontal drainage or a standard uPVC 110 mm branch. Using snap-sockets a pull-tight connection can be created. An expansion socket on every level is mandatory to absorb any pipe expansion and have a tension-free stack-aerator. Inspection openings should be installed according to local regulation, we advise one on every level.
