How and Where to Install a Tank Seal

Installing the Fernco Tank Seal involves:

  1. Preparing the Tank Wall: Ensure the area around the pipe penetration on the tank wall is clean and smooth.
  2. Sizing the Seal: Select a tank seal that matches the outside diameter of the pipe.
  3. Placing the Seal: Position the tank seal around the pipe where it passes through the tank wall.
  4. Securing the Seal: Ensure the seal is snugly fitted around the pipe and sits flush against the tank wall, providing a watertight barrier.
  5. Final Checks: After installation, verify the integrity of the seal to ensure no moisture can travel along the external surface of the pipe.
