Underwater Pool Leak Repairs – No Drain, No Waste, Just Results

At Four States Leak Detection, we specialize in professional underwater pool leak repairs that save our customers time, money, and thousands of gallons of treated water. Instead of draining your entire pool to perform repairs, we dive in and fix the leak right where the problem occurs – underwater and under pressure.

Why Underwater Repairs Are Better

  • No Draining Required

     Draining a pool wastes tens of thousands of gallons of water and can cost hundreds in refilling, chemicals, and                 rebalancing. Our dive repairs eliminate that step entirely.

  • Verified in Real Conditions

    By working in the same pressurized and wet environment where the leak occurs, we can immediately verify that           the repair is holding — no guesswork, no waiting.

  • No Damage to Pool Surfaces

  Draining a pool can lead to structural damage, popped liners, or cracked plaster. Our method preserves your pool's    surfaces and avoids those risks altogether.

  • Chemical & Equipment Savings

When you don’t have to drain, you don’t lose all your chlorine, salt, stabilizer, algaecide, or heat. You also avoid additional wear on pumps and heaters during refill.

How the Process Works

  1. Leak Detected
    Using sonar, dye tracing, or pressure testing, we locate the exact area of leakage.

  2. Dive Repair Begins
    Our trained technician dons scuba gear and specialized underwater tools and adhesives tailored for the repair.

  3. On-the-Spot Testing
    Once sealed, the repair is immediately tested under real pool conditions to ensure it's holding strong.

  4. Final Confirmation
    We provide photo or video documentation of the repair when requested and confirm no further leak is present.
