Remo® Remote Placement Plugs

The Remo® Remote Placement plug provides two advantages-it eliminates the need to enter confi ned spaces and speeds up the pipe plugging process. The system is safer and less expensive to use than conventional plugging methods because it requires no confi ned space equipment to simply block sewer flow. A lightweight aluminum pole system* or a standard 1 1/4″ iron pipe** is used to place the Remo® plug in the sewer system.
