Pool liner leaks can be a serious issue, causing flooding, equipment damage, and costly water and chemical loss. However, patching a pool liner is a simple process that can be done underwater, saving you thousands of dollars and preventing extensive damage. The first step is to identify the leak, then you can use a repair kit with waterproof adhesive or vinyl cement to fix the issue.
How to Patch Plastic Liner Underwater
| Characteristics | Values |
|---|---|
| When to Patch | When there is a decrease in the vinyl-lined pool's water level, particularly in the hot summer months. |
| Inspection | If you can't see the tear, use a leak detector dye to pinpoint the exact spot. |
| Cleaning | Use a soft nylon brush to clean the area around the tear. |
| Patch Type | For small punctures and tears, use waterproof tape or a peel-and-stick patch. For larger tears, use a heavy-duty patch kit. |
| Patch Size | Cut the patch 2-4 inches larger than the tear to ensure full coverage. Round the corners to minimize peeling. |
| Adhesive | Apply adhesive to the inside of the patch. Spread the glue evenly. For underwater repairs, use a specialty underwater repair kit. |
| Application | Place the patch over the tear and work from the inside out to remove air bubbles. Hold the patch firmly in place for a few minutes. |
| Curing Time | For dry repairs, allow 24 hours for the glue to cure. For underwater repairs, do not disturb the patch for 48 hours and allow 4-7 days for a full cure. |

What You'll Learn
Finding the leak
The Bucket Test
Fill a bucket with pool water and place it on one of the pool steps, weighing it down with a rock or brick. If the water level in the pool is significantly lower than the water level in the bucket, it could be a plumbing or equipment leak.
Regular Inspections
Regularly inspect the pool deck, the liner, and fittings for wear and tear. Look for any water leaks or wrinkles in the liner. Wrinkles can form in areas where water is leaking.
Dye Test
If you don't see water leaking, try a dye test. Turn off the filtration system and make sure the water is calm. Put on plastic gloves and add a few drops of pool leak dye or food coloring in the suspected leak area. If the dye is sucked into or pulled toward a hole, you've found the leak.
Electronic Leak Detection
This method uses electrical conductivity from the water to track changes and pinpoint the exact location of a leak. Techniques include pressure testing and listening devices.
Minor Repairs
Fix little problems in your swimming pool before they turn into big ones. Understanding the costs involved can help you budget for repairs. Minor pool repairs can cost as little as the price of a repair kit ($20-$50).
Once you've found the leak, you can decide whether to patch it yourself or call a professional. If the liner is worth trying to patch, you can use a vinyl patch kit or waterproof tape for small tears. For larger tears, a heavy-duty patch kit or professional repair may be required.

Using waterproof tape
Waterproof tape is a quick and easy way to patch a plastic liner underwater. It can be used as a temporary fix to prevent further damage until a more permanent solution can be found. It is also inexpensive and easy to apply.
To use waterproof tape to patch a plastic liner underwater, start by locating the leak. You can do this by using the bucket test method. Fill a 5-gallon bucket with water and place it on the pool steps, ensuring that the outside of the bucket is partially in the pool water. Mark the pool water level on the bucket and turn off the pool pump for 24 hours. If the pool water level is lower than the bucket water level after 24 hours, you have a leak.
Once you have located the leak, cut a piece of waterproof tape that is larger than the tear or hole. The tape should be cut into a round or oval shape, and it should extend at least 2 inches beyond all edges of the repair area. Rounding the corners of the patch can help to prevent the tape from lifting at the corners. It is important to ensure that the surface is clean and free of debris, algae, or any other buildup that could prevent the tape from adhering properly.
Remove the release liner from the tape and quickly apply it over the tear or hole. Smooth out the surface with your hands to remove any air pockets and hold the patch firmly in place for a few minutes to allow the adhesive to cure. For best results, you can place a heavy item, like a brick wrapped in plastic wrap, on top of the patch for 24 hours.
Keep in mind that waterproof tape is not a permanent solution and may start to peel at the corners over time. It is also important to note that overlapping tape may cause leaks, so it is recommended to use a single piece of tape that is large enough to cover the repair area.

Applying a patch kit
Patch kits are recommended for larger tears, as they are more durable and effective than tape. They are also suitable for underwater tears, which can be tricky to fix. The kits consist of a specialty glue and replacement liner that you will need to cut out yourself.
First, identify the area of the leak. You can do this by putting on your snorkelling gear and goggles and searching for the leak by moving around the pool. If you can't find a single leak, take a pool dye and squirt a small amount around your pool liner.
Once you've found the leak, give the area around it a thorough cleaning. Use a soft nylon brush to gently brush the area around the tear and clear away stuck-on dirt and organic material. Make sure the liner surface is free from debris, as adhesive will not stick to a dirty liner.
Next, cut your patch. It should be two to four inches larger than the tear itself. This will prevent the tear from spreading and will cover any minor damage that you can't see. Round the corners of your patch for the best results and to minimise peeling.
Now you can apply the adhesive. Spread the glue evenly across the patch, manipulating it between your fingers. For best results, fold the patch over on itself to spread the glue across the entire surface.
Once the glue is ready, submerge the folded patch underwater and unfold it. Position it over the damaged area and press the patch firmly onto the vinyl. Apply pressure throughout to remove air bubbles or bumps, and ensure a strong seal around the patch.
For dry repairs, allow a minimum of 24 hours for the glue to take hold. For underwater repairs, do not disturb the patch for at least 48 hours and allow four to seven days for a full cure. You can place a clean brick or anything flat and heavy on top of the patch for 24 hours to ensure a strong seal.

Using vinyl adhesive
If you have a vinyl pool, you may need to patch the liner at some point. This is a relatively easy process and can save you thousands of dollars and prevent extensive damage.
First, you need to locate the tear. If there is extreme water loss, the tear is likely to be big and easy to spot. Smaller tears might be harder to find. If you can't see the tear, start by looking at the ground around the pool. If the pool has been leaking for a while, the ground will likely be damp around the area of the tear. Damaged areas of vinyl liners will also sometimes bubble inward toward the pool as water seeps behind it. Once you've found the general area, use a leak detector dye to pinpoint the exact spot.
If the tear is on the bottom of the pool or far from the edge, you will need to get into the water to repair it. Clean the area around the tear with a soft nylon brush to remove dirt and organic material. Trim the patch to size, leaving 2 inches of extra space to ensure full coverage of the tear.
If you are using a vinyl adhesive kit, such as HH-66, clean the vinyl patch with the alcohol wipe provided. Use a brush to apply an even coat of the adhesive to the vinyl patch. Allow the cement to set until slightly tacky. Fold the vinyl patch in half loosely, while the adhesive on the inside is slightly tacky. Submerge the folded patch underwater. Unfold the patch and position it over the tear. Press the patch firmly onto the vinyl and apply pressure to remove air bubbles. Allow to bond for at least an hour. The strongest hold will be achieved after one day.
Some patch products recommend putting weight on the patch for 24 hours while the adhesive cures. If your patch is in a spot where it's possible to do so, place a clean brick or anything flat and heavy on top of the patch.

Adding weight to the patch
If you want to be extra cautious, you can apply a second patch after the first one has completely cured. The second patch should be cut at least two inches larger in diameter than the first patch, making it four inches larger than the hole. This will allow it to adhere to both the pool liner and the first patch.
When using waterproof tape for small punctures and tears, you can overlap the tape to create larger sections for patching. This method is low-cost, durable, and easy to redo if necessary.
It is important to note that patches in areas of the liner close to the stairs, bead, or fittings may be less likely to hold up long-term due to the weight of the pool water pulling on them. These areas are under more stress than other parts of the liner.
