The ABS Plastic Countersunk Plug is a type of DWV (Drain, Waste, and Vent) fitting used to close or seal off the end of a pipe or fitting. It features a flat, countersunk head that fits flush with the pipe or fitting surface. This makes it easy to install and provides a smooth finish, making it ideal for both temporary and permanent sealing in DWV systems.

Purpose of the ABS Plastic Countersunk Plug:

  1. Sealing Openings in DWV Systems: The primary purpose of this plug is to seal off unused or temporarily closed pipe ends in a DWV system. It helps prevent leaks, contamination, and the entry of unwanted materials or gases into the plumbing system.
  2. Pressure Testing: Countersunk plugs are often used when pressure testing a DWV system to ensure that the pipes and fittings are properly sealed and free of leaks. They provide a temporary seal that can be removed once the test is complete.
  3. Maintenance and Repair: During maintenance or repair work, the plug can be used to temporarily close off a section of the system, making it easier to work on specific parts without affecting the entire plumbing setup.
  4. Aesthetic and Safety Considerations: The countersunk design allows the plug to sit flush with the pipe or fitting, which not only improves the appearance but also reduces the risk of damage or injury from protruding parts.
