Cherne Remo Remote Placement Pipe Plug

The Remo® Remote Placement plug provides two advantages—it eliminates the need to enter confined 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 confined space equipment to simply block sewer flow. A lightweight aluminum pole system* or a standard 1¼” iron pipe** is used to place the Remo® plug in the sewer system.Remo® Plug Features:

  • Multi-size design to seal multiple pipe sizes
  • Can be locked at a 90˚ angle to seal openings in drop manholes
  • Can be used as a back plug for sewer tests
