How to Temporarily Fix a Pinhole Leak in PVC Pipe with Tape

Pinhole leaks in PVC pipes can be a frustrating and unexpected problem, but there are temporary solutions available to stop the leak until a permanent repair can be made. One quick fix is to use tape to cover the hole. This method works best for drain lines that don’t carry pressurized water, as the tape will eventually fail under high pressure. However, for low-pressure situations, a tape repair can last for days or even weeks, buying you time to address the issue more permanently.

Supplies Needed

To temporarily fix a pinhole leak with tape, you’ll need the following supplies:

Plastic tape (such as duct tape or electrical tape)
Utility knife or scissors
Rag or paper towels

Steps to Repair the Leak

Turn off the water supply to the affected pipe, if possible.
Drain any excess water from the pipe.
Clean the area around the pinhole with a rag or paper towels to remove any dirt or debris.
Cut a piece of tape large enough to cover the pinhole and extend a few inches on either side.
Apply the tape firmly over the pinhole, pressing down the edges to ensure a tight seal.

It’s important to note that this is a temporary fix and should not be considered a permanent solution. The tape will eventually fail, and the leak will reappear. As soon as possible, you should replace the damaged section of pipe or use a more permanent repair method, such as epoxy or a repair clamp.
