The ACO Triplex-K-2 double backflow stop with shaft system is suitable for installation in the foundation floor slab and provides reliable protection against backflow. The backflow stop can be retrofitted to upgrade a cleaning pipe to a single backflow valve and a double backflow valve. A height-adjustable flange for sealing in WI concrete is available as an accessory. The cover plate can be provided with a selectable surface finish.
