Where Do Pools Usually Leak?

Swimming pools are a great source of entertainment and relaxation, but they can also be a source of frustration when they start to leak. It is important to know where swimming pools usually leak so you can prevent and fix any issues that arise.

In this article, we will discuss five common areas where swimming pools usually leak, how to detect them and what steps can be taken to repair them.

1. Pool Liner

The pool liner is a crucial barrier that helps prevent water from leaking out of the pool. However, over time, the liner can become damaged or deteriorated through normal wear and tear or harsh pool chemicals. You may notice the liner has a tear or puncture if the water level starts to drop in your pool.

One way to detect a leak in the pool liner is to perform a simple bucket test. Fill a bucket with pool water and mark the water level on the inside of the bucket. Place the bucket in the pool, and mark the water level on the outside of the bucket. Wait 24 hours, and then compare the water level inside and outside of the bucket. If the water level inside the bucket has gone down more than the level outside the bucket, then there is a leak in the pool liner.

To repair the pool liner, you can use a patch kit or have a professional install a new liner.

2. Skimmer

The skimmer is located on the side of the pool and is used to collect any leaves and debris that float on the water's surface. The skimmer is connected to the pool's plumbing system and can easily become damaged or leak water if its seal is broken.

If you suspect that the skimmer is leaking, add food coloring to the water around the skimmer. If the water near the skimmer is discolored after a few hours, then there is a leak.

To fix the skimmer, it needs to be taken apart and resealed. This is a job that is best left to a professional.

3. Pipes

The pipes that deliver water to and from the pool can become damaged through normal wear and tear or changes in weather. If you notice that your pool water levels are low and there are no visible leaks, then it's possible that the pipes are leaking.

A professional can use a pressure test to detect leaks in the pipes. Once the source of the leak is identified, the damaged section of the pipe can be repaired or replaced.

4. Pool Equipment

The pool equipment, including pumps, filters, and heaters, are all essential parts of the pool's operation but can also be a source of leaks. If you notice that there is water around the pool equipment, then there is a good chance that it's leaking.

To detect a leak in your pool equipment, you can turn off the pool pump and see if the water level remains constant. If the water level drops, then there is a leak in the equipment.

Depending on the source of the leak, the equipment may need to be repaired or replaced.

5. Ground Settling

Over time, the ground around the pool can settle and cause the pool to shift slightly. This can create stress on the pool's structure, which can lead to leaks.

If you notice any cracks in the pool's structure, then it's possible that there's a leak caused by ground settling. A professional can assess the damage and recommend repair options.


Swimming pools are a major investment, and it's important to take care of them. Knowing where pools usually leak and what signs to look for can help you prevent and repair leaks before they cause any serious damage to your pool. If you suspect that your pool is leaking, don't hesitate to call a professional to assess the situation and recommend the best course of action.
