How To Find The Leak In A Pool Liner?

A pool water leak is the kind of fault that needs to be fixed immediately. After all, it’s not just water loss. Delaying repairs can lead to more severe consequences that will require more time and resources to fix.

It is also necessary to fix not only the leak itself, but also the reason why it occurred. Finding a hole in a pool liner can be challenging, but there are several effective methods to locate it.


We Can Help You Solve Your Leaking Liner Problem

    Water Loss In The Pool

    Here are some steps you can follow:

    • Visual Inspection: Start with a thorough visual inspection of the pool liner, looking for any obvious signs of damage, such as tears, punctures, or discoloration. Pay special attention to corners, seams, and areas around fittings.
    • Water Level Check: Monitor the water level in your pool. If you notice a significant drop in water level over a short period, it may indicate a leak. Mark the water level with tape and check back after a few hours to see if it has dropped.
    • Dye Test: Use a dye test to help locate the hole. With the pool water still, take a small bottle of food coloring or dye and squirt it near suspected areas of the liner. If there is a hole, the dye will be drawn into the hole, making it easier to identify the location.
    • Listen for Hissing Sounds: If the pool is not too deep, you can put your ear close to the surface of the water and listen for any hissing sounds, which may indicate air escaping from a hole.
    • Submerge and Inspect: If you are comfortable doing so, you can submerge yourself in the pool and closely inspect the liner while underwater. Look for bubbles or areas where water is flowing out, which can help pinpoint the location of the hole.
    • Use a Pool Leak Detection Kit: If you are unable to find the hole using the above methods, consider using a pool leak detection kit, which often includes specialized tools and dyes to help locate leaks more effectively.
    • Professional Help: If all else fails, consider hiring a professional pool technician who has experience in leak detection. They can use advanced tools and techniques to locate and repair the hole in your pool liner.
    • Poor quality materials and non-compliance with building codes. Cheap, low-quality materials combined with poor construction techniques can lead to many problems, including leaks.

    By following these steps, you should be able to locate any holes or leaks in your pool liner effectively.

    You can avoid these issues by using Cefil reinforced 60 mil pool liner for your pool.

    Why Cefil Reinforced Liner Is Ideal for Pools

    Every pool owner wants their swimming pool to be not only a favorite recreational space, but also attractive, practical with minimal maintenance costs.
    This is exactly what the reinforced liner offers:

    High resistance to external influences. Our reinforced PVC liner has a three-layer structure. The middle layer is a strong reinforcing mesh. It is also quite thick, its thickness is 60 mil. This makes it well resistant to punctures and cuts. This minimizes the occurrence of leaks.

    • Airtightness and long service life. Even if there are cracks and other defects in the concrete pool bowl, the liner retains its tightness. And this eliminates the appearance of leaks, which can not provide other types of liners.
    • Resistance to UV rays and chemicals in the water. Liner is covered with a layer of special varnish, which protects the vinyl from the effects of UV rays and chemicals. This reduces the risk of fading of the liner pattern and extends its life.
    • Simple, inexpensive and quick installation. Compared to tiling a pool bowl with ceramic tiles, mosaics, plaster or pebble, installing a liner is much quicker. And by selecting the pattern on the liner, you can, if desired, imitate the full resemblance to the same tile or mosaic.
    • Aesthetics. A wide choice of color shades and patterns makes it possible to perform the lining of the pool to your taste. In addition to the smooth surface of the liner it can also have a rough texture. It not only gives a certain external naturalness, but also has anti-slip properties.

    Thus, our reinforced liner is a practical and durable solution not only for fixing leaks, but also for other possible problems.

    How To Eliminate The Leaks

    If the pool water level drops more than half an inch in a day, there may be a water leak. The water level can also drop due to natural evaporation, especially on hot days. But not that much. And if you cover your pool when you’re not using it, there should be little to no water level drop from evaporation.

    Leaks can occur due to leaks in the pipes that supply and discharge water to filters, skimmers and heaters, or due to punctures in the liner.

    Leaks in pipes can be identified by visually inspecting them. Unless the pipes are in the ground and cannot be inspected. If the pipes are wet — this is an indication of loss of tightness. In this case it is necessary to repair or replace them. Also inspect filters, valves, heaters.

    Check for leaks in pipes in the ground by interrupting the water circulation through the pipes. To do this, turn off the pump and close all valves. If the water level has stopped dropping, the cause is in these pipes.

    Liner leaks can initially be identified by the condition of the pool bottom. If it was hard and is now soft, like you are walking on a mattress, this means that water is pooling on the bottom under the liner, this usually happens with thick liner such as 20 mil or 27 mil because these types of liner do not have a reinforced polyester mesh and are easily torn.

    Water can get under the liner at the bottom of the pool through punctures or cuts caused by sharp objects. Water can also enter through gaps in poorly secured lamp covers, nozzles, and skimmers. We use special types of skimmers and jets for liner pools that have no analogues on US market which makes installation of a liner for pools in non-competition with other companies in the installation of reinforced 60 mil liner for pools. To find such places, it is necessary to thoroughly inspect the entire surface of the pool. This is usually done with the help of a scuba mask. On suspicious places from a syringe with a plastic tip apply food coloring. If it is sucked under the liner, it means that there is a puncture. There may be more than one. Therefore, it is necessary to examine the entire pool.

    Specialists should be brought in to inspect and repair the pool. Independent attempts to solve the problem can only worsen the situation.
