Having a leak in your pool is never fun, and it can be even more stressful when you don’t know where the leak is coming from. Maintaining your swimming pool can be costly, so finding ways to cut back on costs is essential.

Fortunately, finding leaks in your pool isn’t too difficult if you know what you’re looking for. There are several signs that will indicate that something is wrong with your skimmer.

This article covers everything you need to know about finding a leak in your pool skimmer and the common causes of leaks so you can avoid them.

How to find leaks in the pool skimmer

Check the skimmer before diving into leaks

Before you start testing your pool’s skimmer, you’ll want to make sure there is a leak happening. It’s easy to get caught up in testing skimmers when you’re looking for a leak, but you’re probably looking at a problem with your pump or even your plumbing.

By focusing first on finding the leak, you’re less likely to do more damage than you need to accidentally. Usually, when skimmers start to leak, you’ll notice algae growing on the walls and in the bottom of the skimmer.

This is because the skimmer is no longer actively removing the dirt, algae, and leaves that enter your skimmer. If you don’t notice any issues with your skimmer, then there’s a good chance your pool pump is the issue. A new pump is super expensive, so you’ll want to ensure it’s the issue before spending it.


Know what to look for when checking a pool skimmer

Most skimmers leak from the ball valves that control the flow of water. If you’re having trouble finding the source of the leak, you’ll want to start by looking for damage to your skimmer.

You may notice that there is damage to your skimmer, or you may notice algae growing in the skimmer. If you can’t find any damage to your skimmer, then you’ll want to look for damage to your plumbing.

You may be able to see when your skimmer is leaking by looking at where the skimmer connects to the pool’s plumbing. If you can see damage to your plumbing, then you’re more likely to find the leak that way.


Use special equipment to find leaks

If you don’t have access to a leak-detection tool, you’ll want to use special equipment to find a leak. These tools are designed to detect leaks and are usually handheld.

There are a few different types of leak-detection equipment, so you’ll want to make sure you choose the right one for your needs. One type of leak-detection equipment is designed to find leaks in above- or below-ground pools.

These are generally easier to use than devices that can detect leaks in both above and ground pools. You’ll want to ensure you choose the right type of leak detection for your situation.


If you can’t find any signs of leakage, look at other parts of the pool

If you’ve checked your skimmer and are still unable to find the source of your leak, you may want to take a look at the rest of your pool.

There are several parts of a pool that can be damaged and cause a leak, so you may want to take a look. Here are some of the most common parts of a pool that can cause a leak:  Pumps – Pumps are one of the most common parts of a pool that cause leaks. Even the best, most expensive pumps can sometimes have issues.

  • Inlet valves – An inlet valve is responsible for directing the flow of water from your pool into your skimmer. If this part of your plumbing is damaged, your pool will have a hard time draining properly.
  • Skimmers – If the walls or the base of your skimmer is damaged, it will cause your pool to have less water pressure in that area. This will increase the likelihood of a leak.
  • Pool wiring – Pool wiring can get damaged and cause leaks. If you have an older system, it’s worth checking.
  • Faucet – Faucet leaks can also be hard to find. You may notice a leak, but have no idea where the leak is coming from.
  • Pool liner – Pool liners need to be replaced every few years. This can cause damage to your pool walls and piping, which can lead to a leak.


Common causes of leaks in a skimmer

Skimmers are the most common way to keep your aquarium clean. It is a part of every aquarium setup, so it is important to know how to properly maintain it. The main cause of skimmer leaks is debris build-up.

Some of this may result from poor filtration, but it will typically be caused by an accumulation of food waste and other organic matter in the tank. In addition, a clogged skimmer can also result from buildup on the impeller or shaft that causes excessive wear on the pump.

A clogged skimmer can also be caused by water leaking into the motor housing. All of these problems are best addressed by cleaning out your skimmer at least once a week.

Use a high-quality sponge with activated carbon to remove any solid waste that may have built up inside the pump head. This will help prevent wear and tear on the pump as well as improve skimming performance over time. If you notice any significant wear on your skimmer impeller, replace it immediately! 



Finding a leak in your skimmer is one of the most frustrating things about owning a pool. It can be difficult to know where to look, and it can be hard to tell if the leak is actually coming from your skimmer, or from somewhere else.

Luckily, finding a leak in your skimmer isn’t too difficult if you know what to look for. By following these tips, you’ll be able to quickly find the source of any leaks in your skimmer.
