To fix a leak in an above-ground pool liner, follow these steps:
1. Locate the leak by inspecting the liner for any visible holes or tears.
2. Clean and dry the area around the leak to ensure proper adhesion of the patch.
3. Apply a patch specifically designed for pool liners, following the manufacturer’s instructions.
4. Press the patch firmly onto the liner, smoothing out any bubbles or wrinkles.
5. Allow the patch to cure for the recommended time before refilling the pool.
6. Monitor the patched area for any signs of further leaks and repeat the process if necessary.
Remember to always follow the instructions provided with the patch and seek professional help if the leak persists or if you are unsure about the repair process.
Above-ground pools typically have a flexible vinyl liner that fits into a metal frame. The liner is usually made of laminated PVC material that can conform to the ground but is also prone to punctures. Fortunately, fixing a pool leak is a relatively simple DIY task that can be done underwater without draining the pool.
Determining the Source of the Leak
Before repairing a pool leak, it’s important to identify where the water is leaking from. This can be done through leak detection methods to determine if it’s a liner leak or a leak from another component.
It’s normal for swimming pools to lose some water due to evaporation, especially in hot and dry or windy climates. Additionally, active swimmers can splash out water. If your pool loses about an inch or two of water per day, it’s likely not a cause for concern. However, if the water loss is more significant, especially when the pool is idle, it’s a sign of a liner leak.
Another indication of a liner leak is the location of the puddled water on the ground. Liner leaks, especially those at the bottom of the pool, can create a wet mess around the pool area. A small leak may result in moist soil around the pool, while a larger tear may cause bubbling water at the base of the pool.
If the leak is at a hose connection or strainer joint, it will be more visible, and the wet ground will be limited to that area. Additionally, if the leak is in a water line connection, the pool water level will drain to that point and stop decreasing.
Repair Options for Liner Leaks
There are several options for repairing leaks in a vinyl pool liner, but one solution is the most effective. It’s important to patch the leak quickly to prevent water waste and minimize damage to the liner. Pool liners are designed to be in constant contact with water, and prolonged exposure to the sun can make them brittle and prone to cracking. Repair options include:
- Waterproof patching tape: There are various types of waterproof tapes available that can be used to fix small holes in a pool liner. To use it, cut a piece of tape, round off the corner of the patch with scissors, place it over the hole, and hold it down for a few minutes until it bonds securely. Before applying the tape, it’s important to thoroughly clean the liner material to ensure a strong bond. However, it’s important to note that patching tape is only a temporary solution and will eventually fail.
- Peel-and-stick patches: Peel-and-stick patches are similar to waterproof tape and come in pre-cut sizes. After cleaning the liner surface, you simply peel off the backing paper, apply the patch over the hole, and hold it in place until it bonds.
- Vinyl liner fabric with vinyl glue: The best option is to use genuine pool liner material and vinyl glue. With this type of patch, the vinyl glue melts the patch material into the pool liner, creating the strongest bond. You can purchase the liner material and vinyl glue together as a patch kit or separately. For example, you may be able to buy liner material from the pool manufacturer that matches your liner and then purchase a can of vinyl glue separately.
Out of these methods, using actual vinyl liner material with vinyl glue is the most durable and long-lasting option. However, it’s important to keep in mind that no patch will be as strong as the original liner. If your vinyl pool liner consistently develops leaks, it is recommended to replace it within a year or two.

How to Patch a Liner Leak
Step 1: Clean the Pool
Begin by thoroughly scrubbing and vacuuming the bottom of the pool to remove dirt, algae, and discoloration. A clean liner will make it easier to spot leaks.
Step 2: Identify the Leak
Most leaks occur at the bottom of the liner, but side leaks can also happen if the pool is heavily used. For example, children may let their dogs swim in the pool, and their toenails can puncture the side of a vinyl pool. Side leaks are usually noticeable as water drains down the outside surface of the pool.
To identify leaks, wear swim goggles and inspect the bottom of the pool closely. Leaks will usually appear as dark spots or small tears. Carefully probe any small spots with a toothpick to determine if there is a puncture that goes through the liner. If there is, leave the toothpick in place to mark the location of the puncture.
One alternative method involves using a small squeeze bottle filled with food coloring dye. When you encounter suspicious areas, release a small amount of dye and observe closely to see if the dye is carried through the hole with the flow of water. Mark the area of the hole for easy identification later.

Step 3: Clean the Liner
To ensure proper adhesion of the patch, the liner must be as clean as possible. Use a scrubbing sponge to scrub the area immediately surrounding the hole, being careful not to worsen the damage. Once the area is clean, make sure to mark the hole or tear for easy location when applying the patch.
Step 4: Prepare the Patch
Cut a piece of patch material that is large enough to cover the damaged area with an additional 2 inches of material on each side. Round the edges of the patch, as squared patches are more prone to tearing over time.
Following the instructions provided by the manufacturer, apply vinyl glue to the underside of the patch. Fold the patch upward around the tip of your finger as you prepare to dive down and apply it over the hole.
Step 5: Apply the Patch
For a successful patch, it is crucial for it to lie flat against the surface of the liner without any air bubbles in the patching material. This step is the most important one.
Start by pressing the center of the patch directly over the hole in the liner, then smooth it outwards towards the edges of the patch. Continue to apply firm pressure until the patch is securely bonded. You can place a heavy weight on top of the patch to keep it in place, or apply pressure with your foot. Follow the recommendations provided by the manufacturer, as most suggest holding the patch in place for approximately two minutes to allow the glue to set and bond.
Step 6: Apply a Double Patch (Optional)
Some pool owners have found success by applying a second vinyl patch over the first, known as double-patching. The second patch should be at least 1 inch larger than the first patch on all sides so that the edges of the second patch make direct contact with the pool liner. Apply vinyl glue to the entire bottom surface of the second patch to ensure it bonds to both the pool liner and the first patch.
If your pool liner requires frequent repairs and is beginning to look worn with patched areas scattered across it, it may be time to start considering a new liner. Typically, above-ground pool liners last around 10 years, with six years being more common.
