Will Duct Tape Stop A Water Leak?

Duct tape is water-resistant and can help temporarily stop a water leak providing the leak isn’t high pressure and providing you wrap it correctly.

Will Duct Tape Stop A Water Leak

To stop a leak with duct tape, follow these steps:

  • Take one piece of duct tape and place it tight and flat against the leak, ensuring that no air is trapped underneath.
  • Take 4 or 5 pieces of duct tape and overlap these with the first piece of duct tape to tightly seal the edges to prevent water from coming out.

Now let’s be clear duct tape is never going to be a long-term solution to a leak. Depending on the severity of the leak duct tape may only stop the leak for a few minutes.

If the leak is a slow leak with low pressure and it consists of a just few drops a minute then duct tape could seal the leak for weeks or even months.

If the leak is pouring out then you will struggle to get duct tape to stick over it, and you will certainly struggle to seal it for anything more than a few minutes.

You are likely to have far better results with Gorilla tape, this is designed with a thick adhesive layer that helps it create a tightly sealed bond which is far more effective at keeping water out than duct tape.
