If you have a pool and you are losing a lot of water on a regular basis, you may have a hole in your pool liner. Finding a hole in a pool liner is definitely a daunting task, but an important one. Finding a hole in your pool liner allows you to fix it, which prevents it from getting larger and causing more damage to the liner. This article will help you determine if you have a hole in your pool liner. Additionally, the article will teach you how to find the hole in your pool liner so that you can either fix it yourself or call a pool professional to fix it for you.
How to Find A Hole in A Pool Liner
Determine if your pool liner is leaking. To do this, fill your pool to its normal level. Get a bucket and fill it with water. You may also want to weigh it down with some rocks so that it doesn't damage the liner if it gets knocked over. Put the bucket on your pool steps, with the top of the bucket sticking out. Make sure the pool water level and the bucket water level match. If you don't have pool stairs, you can try to balance if on the top rung of the pool ladder. Submerging most of the bucket into the pool water will ensure the temperature of the water in the bucket is the same as the temperature of the water in the pool, which means they will evaporate at the same rate. Mark how much water is in the pool and how much water is in the bucket by placing a pencil mark or a piece of scotch tape at each water level. Wait 24 hours, and then measure how much water was lost in the pool versus in the bucket. If more water was lost in the pool than in the bucket, you have a hole in your pool liner.
Determine if something is puncturing the pool's liner. Slowly drop food coloring around the pool's ladder or stair strip, skimmer faceplate, and return faceplate. If there is a hole around these areas, you will see the food coloring being sucked into the hole. If the hole isn't near the stair strip, ladder, or skimmer or return faceplates, you will need to find the hole elsewhere in the liner. This process may be difficult because many liners have a design on the bottom and sides of the pool floor and walls.
Do a visual inspection of the pool liner. If you see any abnormalities, use the food coloring to determine if it is a hole in the liner, as described above in step 2.
Use your hands to feel along the walls and bottom of the pool to find the liner tear or hole. This will be a daunting task, but doing a thorough job will ensure you will only have to go around the pool once to find the hole. If you have a friend who dives, you may want to ask him or her to bring over his or her diving equipment and check out the bottom of the deep end for you. This will be less time consuming than holding your breath, going down to the bottom of the pool, and looking for the hole yourself.
Once you've found the hole in your liner, you will be able to fix it yourself or call a pool professional to come fix it for you. Fix the leak as soon as you can to avoid it becoming larger.
