Read on to protect your pool, save money, and enjoy every swim—without the worry of water loss or costly repairs.

What Are the Most Common Causes of Pool Leaks?

Pool leaks can happen for many reasons. The most frequent causes include:

• Cracks in the pool shell, especially in concrete pools
• Damaged or worn-out skimmer and return line fittings
• Broken or loose tiles and deteriorated grout
• Faulty main drain or suction lines
• Aging pool plumbing and underground pipe leaks
• Issues with pool lights or the pool deck interface

Even a small leak can lead to significant water loss and expensive repairs if left untreated. Regularly inspecting your swimming pool and spa for visible cracks, loose tiles, or wet spots around the pool can help catch leaks early.

How Can You Tell If Your Pool Has a Leak or Just Evaporation?

It’s normal for a swimming pool to lose some water due to evaporation, especially in Austin’s hot climate. However, losing more than 2 inches per week could indicate a leak.

Try the bucket test:

• Fill a bucket with pool water and place it on a pool step.
• Mark the water level inside and outside the bucket.
• Wait 24-48 hours.
• If the pool water drops more than the bucket water, you likely have a leak.

Other signs include sudden spikes in your water bill, soggy spots around the pool, or air bubbles in the return line. These could indicate a leak in the pool, not just normal evaporation.

What Are the Signs of a Swimming Pool Leak?

Be on the lookout for these warning signs:

• Water level drops faster than normal
• Wet spots or erosion around the pool deck
• Cracks in the pool shell, tile, or grout
• Algae growth despite proper chemical balance
• Air in the pump and filter system
• Constant need to add water to maintain the level

If you notice any of these, it’s time to investigate further or call in a pool leak detection expert.

How Does Professional Pool Leak Detection Work?

At Leak Finder Pro, we use industry-leading Leaktronics equipment for pool leak detection in Austin, TX. Our process includes:

• Pressure testing: Isolates plumbing lines and checks for pressure drops, which indicate leaks.
• Acoustic listening devices: Pinpoint the sound of escaping water, even underground or beneath the pool deck.
• Dye testing: Non-toxic dye is used to visually confirm the source of the leak in the pool or spa.
• Thermal imaging: Detects hidden leaks by identifying temperature changes caused by escaping water.
• Video scope inspections: Allows us to see inside pipes, skimmers, and main drains for visual confirmation.

This advanced leak detection ensures we find the exact source of the leak, minimizing unnecessary digging or repairs. Our Leaktronics equipment lets us find even the most elusive leaks quickly and accurately, ensuring your pool is fixed right the first time.

What DIY Methods Can You Use to Find a Pool Leak?

While professional leak detection is best for complex leaks, you can try these DIY steps:

• Monitor the water level: Mark the water line and check it daily.
• Bucket test: Helps distinguish between evaporation and a leak.
• Dye test: Use food coloring or pool dye near suspected cracks, skimmer, or main drain. If the dye is drawn into a crack, you’ve found the leak.
• Check equipment: Inspect the pump, filter, and plumbing for dampness or drips.

If you find a small leak, you may be able to patch it temporarily. For anything more serious, call Leak Finder Pro for expert leak detection and repair.

How Are Pool Leaks Repaired?

Pool leak repair depends on the type and location of the leak:

• Small cracks: Can often be repaired with underwater epoxy or pool putty.
• Tile and grout: Grout removal and replacement or tile repair may be needed.
• Vinyl liner: Use a vinyl patch kit to fix tears or punctures.
• Skimmer or return line: Replace gaskets, tighten fittings, or apply sealant.
• Plumbing leaks: May require pipe replacement or re-sealing with specialized materials designed to seal leaks.

Professional repair service ensures the leak has stopped and prevents further water loss or damage to your pool and spa.

What Is Fix-A-Leak and Does It Work?

Fix-A-Leak is a concentrated sealant designed to stop leak water loss in pools and spas by sealing small cracks and holes—up to 1/8 inch in diameter. It’s poured directly into the pool or spa and circulates to fill voids.

• Works best for minor leaks in vinyl pool liners, skimmers, or pool plumbing.
• Not a permanent solution for major leaks, structural cracks, or underground pipe issues.
• Always follow up with professional leak detection and repair for lasting results.
