Screws and nails are just two of the common causes of small holes in PVC pipe. Luckily, the majority of these holes are created in non-pressurized drain lines. The larger drain lines that move wastewater from your upstairs bathroom or laundry room out of your home and into your septic or city sewer connection are large and therefore are installed close to the drywall of your home. Plastic repair epoxy creates a permanent repair on small holes made in non-pressurized PVC pipe.
Scuff the surface of the PVC pipe where the hole is located with the 200-grit sandpaper. Roughen an area that extends at least 1/4 inch past each side of the small hole, as this will allow the plastic repair epoxy to bond firmly to the surface of the PVC pipe.
Wipe the sanded area of the PVC pipe with a dry rag to remove sanded dust from the repair area.
Mix enough plastic repair epoxy to create a ball roughly the diameter of a dime.
Press the dime-sized ball of plastic repair epoxy firmly onto the scuffed surface of the PVC pipe, while keeping the plastic repair epoxy ball centered over the small hole in the PVC pipe.
Work the plastic repair epoxy into the surface of the PVC pipe with your fingers and allow it to cure per the manufacturer's installation instructions.
Sand the cured plastic repair epoxy with 60-grit sandpaper to blend the repair into the surface of the PVC pipe, then sand over the area with the 200-grit sandpaper to remove the sanding marks created by the 60-grit sandpaper.
Wipe the repaired surface of the PVC pipe with the dry rag to remove sanding dust from the PVC pipe and complete the process of repairing a small hole in PVC pipe.
