What Are the Signs of a Pool Leak?
The first step in pool leak detection is knowing what to look for. Some common signs of a swimming pool leak include:
A noticeable drop in water level (more than 1/4 inch per day)
Wet or soggy spots around the pool or in your yard
Cracks in the pool liner, tile, or deck
Increased need for pool chemicals
Air bubbles in the pool pump or return lines
Higher than normal water bills
If you notice any of these, your pool may be losing water due to a leak rather than just evaporation.
How Can I Tell If It’s a Leak or Just Evaporation?
Not every drop in pool water level is a sign of a leaking pool. Arizona’s hot, dry climate means pools lose water to evaporation, especially in the summer. The bucket test is a simple way to tell the difference:
Fill a bucket with pool water and place it on a pool step, making sure the water inside the bucket is at the same level as the pool water outside.
Mark both water levels with tape.
After 24 hours, compare the water loss in the bucket to the pool. If the pool is losing more water than the bucket, you likely have a leak.
This test is easy, reliable, and recommended by pool professionals everywhere.
Where Do Pool Leaks Usually Occur?
Pool leaks can happen in several areas, including:
The pool liner (tears or punctures)
Around the skimmer, returns, or pool lights
Cracks in the pool shell or tile
Pool plumbing and equipment
The pool deck or coping
A thorough visual inspection around the pool and equipment can help you spot obvious signs of a leak, like cracks, wet spots, or loose tiles and understand the source of the leak.
What Is the Dye Test and How Does It Work?
The dye test is a simple but powerful way to pinpoint the exact location of a leak in your pool:
Turn off the pool pump so the water is still.
Add a few drops of pool leak detection dye or food coloring near the suspected area (like a crack, fitting, or skimmer).
Watch the dye—if there’s a leak, it will be drawn toward the source, revealing the exact spot.
This method works well for finding leaks in the liner, around fittings, or in small cracks.

If you can’t find the leak yourself, it’s time to call in the experts. At Optimal Pool Leak Detection, we use industry-leading Leaktronics equipment, which includes:

Why Is Early Leak Detection Important?
Catching a pool leak early can save you thousands of gallons of water, prevent structural damage, and reduce your repair costs. Leaks that go undetected can undermine your pool’s foundation, damage landscaping, and even affect nearby structures. Prompt leak detection and repair protect your investment and keep your pool safe and enjoyable.
What Should I Do If I Suspect a Leak?
Perform the bucket test to confirm if your pool is leaking.
Inspect the pool liner, fittings, and equipment for visible signs of a leak.
Don’t wait—addressing leaks early prevents bigger problems down the line.
Can I Patch a Swimming Pool Leak Myself?
Small leaks in the pool liner or around fittings can sometimes be patched with a pool patch kit. However, for larger leaks, leaks in the plumbing, or leaks you can’t locate, it’s best to call a professional. DIY repairs may only be temporary and can miss hidden issues that require expert attention.
