Leak In Your Swimming Pool's Liner? Learn How To Find And Fix It

Posted on: 6 April 2015

If you are often refilling your pool with water because the water level keeps dropping, chances are there could be a small hole hiding in the liner. Finding and fixing these holes is a task that you can do all by yourself if you follow these simple steps.

Tools & Materials

Before you can get started, you will need the following tools and materials.

  • Vinyl patching material
  • Food coloring
  • Water bottle
  • Tape measure
  • Waterproof tape
  • Bucket

Determining If There Is A Leak

In order to figure out if there is a leak in the swimming pool liner, you need to do an experiment. Water will naturally evaporate on its own, so you need to determine if the water level is dropping due to a leak or evaporation.

Fill up a bucket with some water from the pool, and use waterproof tape to mark the height of the water level in the bucket. Leave it next to the pool for 24 hours. Mark the water levels inside your pool as well with your tape. If you come back the next day and the pool dropped lower than the water in the bucket, there is a leak in your pool's liner.

Locating The Hole

Fill up a plastic bottle with water and add a couple drops of food coloring -- the darker the better. Carefully poor the water into the pool, and sit back and watch the colored water travels to the hole. It might take awhile, but it is a great way to figure out the leak's location without draining the pool.

Fixing The Leak

You can fix the leak using a vinyl patch, preferably one that has a self-adhesive backing that can be applied underwater so you can keep the pool full.

Create a patch that is a couple inches larger in diameter than the hole. It helps to round the corners of the patch so that it sticks the liner better. Place the patch on top of the hole, and carefully remove the plastic backing that will expose the sticky part of the patch. Roll it over the hole from top to bottom, as it will help remove air bubbles and create a bond that is watertight with the vinyl liner.

If you are having difficulties finding the leak or applying the patch, you may need professional help. Contact a local swimming pool repair company like Budget Pool & Spa Tech Inc. in your city that can take care of the leak for you.
