There’s nothing quite like having an in-ground pool. Whether it’s a quiet morning swim or a lively pool party, the benefits of having your own backyard oasis are endless. But what happens when your pool isn’t holding water like it used to? A pool leak can be more than a nuisance—it can lead to expensive water bills, property damage, and even structural problems.
Luckily, with the right know-how, you can catch the signs early and decide whether it’s something you can handle on your own or if it’s time to call in the pros. Here are five ways to figure out if your pool is leaking, plus some guidance on what to do next.

The Bucket Test: A Simple Way to Confirm a Leak
If you suspect your pool is leaking, the bucket test is one of the easiest ways to find out. Here’s how you can do it:
Grab a bucket, fill it with water, and place it on a step inside your pool. Mark the water level inside the bucket and the water level outside on the pool wall. Then let it sit undisturbed for a day or two—just make sure the pump is off during this time.
After waiting, check the levels again. If the pool’s water level dropped more than the bucket’s, chances are you have a leak. This simple test works because it separates natural evaporation from actual water loss. It’s a great DIY option for homeowners to confirm whether a problem exists before diving into more involved inspections.
While the bucket test is straightforward, finding the exact source of the leak can get tricky. Depending on what’s causing the issue, you might be able to fix it yourself—or you might need expert help.
Losing Water Faster Than Evaporation
Every pool loses a bit of water to evaporation, especially during hot or windy weather. But if your pool seems to be losing inches of water every week, it’s worth taking a closer look. A good trick to narrow things down is to check for water loss overnight. Since evaporation slows when the temperature drops, noticeable water loss in the cooler hours usually signals a leak.
Once you’ve ruled out evaporation, the next step is to figure out where the leak is. If you notice small cracks in the pool surface or a loose fitting around a pool light, you might be able to patch things up yourself with a repair kit. But if the problem lies in underground plumbing or a drain system, it’s usually time to call a professional.
Wet Spots Around the Pool
Have you noticed soggy patches of grass or wet areas in your yard, especially near the pool? That could be a sign of water leaking out of the pool into the surrounding soil. This kind of leak can cause more than just muddy spots—it can weaken the ground around your pool, leading to cracks or shifting in the pool’s structure.
If you spot wet areas and suspect a leak, it’s important to act quickly. Minor issues like surface cracks can sometimes be repaired with pool putty or an underwater sealant. But if the water is escaping through underground plumbing or structural damage, you’ll want a professional to assess the situation. These repairs can be complex and require specialized tools to avoid making the problem worse.
Higher Water & Energy Bills
If your water bill has started climbing for no obvious reason, your pool might be the culprit. A leaking pool requires constant refilling, which can drive up water usage. At the same time, leaks in the pool’s plumbing or filter system can put extra strain on your pump, causing your energy bill to spike as well.
To confirm whether the pool is causing these extra costs, keep an eye on your bills over a few months. You can also try turning off your pool equipment for a short time to see if it affects your utility usage.
If you do find a connection, it’s likely time to bring in a pool repair specialist. Issues like cracked pipes or malfunctioning equipment often require professional expertise to fix properly.
Air Bubbles & Strange Noises
Your pool’s equipment can also give you clues about a leak. If you see air bubbles in the water coming back into the pool or hear unusual gurgling noises from your pump, it could mean there’s a suction leak. This happens when air gets into the plumbing system, often through a damaged suction line.
These types of leaks are tricky to pinpoint without the right tools. Professionals use techniques like pressure testing and electronic listening devices to find the problem without damaging the pool or its surroundings. While you might be tempted to troubleshoot this issue yourself, it’s best left to an expert. DIY attempts can sometimes do more harm than good, especially with something as intricate as a pool’s plumbing system.
Can You Fix a Pool Leak Yourself?
The short answer is: it depends. If the issue is small and easy to access, you might be able to handle it on your own. For example, minor cracks in the pool’s surface can often be patched with a repair kit, and simple fixes like replacing a leaky O-ring on your pump don’t require professional help.
But more serious problems—like leaks in underground plumbing, structural damage, or faulty drains—are a different story. These repairs often involve specialized equipment, and attempting a DIY fix can end up making the situation worse. If you’re not sure what’s causing the problem, it’s always safer to call in a professional.
Why Early Detection Matters
Catching a pool leak early is about more than saving water. It’s about protecting your pool, your property, and your wallet. A small leak can turn into a much bigger problem if left unchecked, leading to costly repairs and even damage to your home’s foundation or landscaping.
The best approach is to stay vigilant. Regularly inspect your pool, monitor your water and energy bills, and keep an eye out for signs like soggy ground or noisy equipment. If you suspect a leak but can’t locate it, don’t hesitate to bring in a pool expert. They’ll have the tools and experience to diagnose and fix the problem before it gets out of hand.
Take Action to Keep Your Pool in Top Shape
Your in-ground pool is a valuable part of your home, and keeping it in good condition ensures you can enjoy it for years to come. By learning how to spot the signs of a leak and knowing when to call in the pros, you’ll be better equipped to handle any issues that come your way.
If you think your pool might be leaking, don’t wait to investigate. Whether it’s a simple fix or a job for a professional, addressing the problem early will save you time, money, and frustration. With a little care and attention, you can keep your pool running smoothly and enjoy everything it has to offer.
