Commercial Pool Leak Detection: What Should You Expect?

Swimming pools are an integral part of residential and commercial establishments in the sun-soaked state of Arizona. From hotel resorts to condominiums and fitness centers, commercial swimming pools offer visitors and residents a refreshing escape from the desert heat. Yet, ensuring that these pools remain in optimal condition is of paramount importance for both safety and cost-efficiency. Among the most critical challenges faced by commercial pool owners is the timely detection and repair of pool leaks. In this article, we’ll delve deep into what one should expect from commercial pool leak detection.

Why Is Commercial Pool Leak Detection Important?

The sheer volume of water and the size of commercial pools make them susceptible to substantial water losses if there’s even a minor leak. Water leaks can not only lead to significant wastage of water but also increase your utility bills. Further, unchecked leaks can damage the pool’s structure, its surroundings, or even compromise the integrity of nearby buildings.

Initial Signs and Symptoms of a Pool Leak:

Before diving into the detection process, let’s understand the early signs that suggest a possible leak:

  • A noticeable drop in water level, other than due to evaporation or splash-out.
  • Wet spots around the pool area.
  • Air bubbles in the return lines.
  • Pool deck uplifting or sinking.
  • Increased water bills without a corresponding increase in water use.

The Detection Process:

When you hire a professional for commercial pool leak detection, here’s what you should expect:

Consultation and Preliminary Inspection: Initially, the technician will have a discussion with you to understand any observations you’ve made or concerns you have. They will also conduct a visual inspection to identify obvious signs of leakage.

Pressure Testing: The pipes and return lines are typically the first suspects. A professional will often use pressure testing to determine if there’s a loss of pressure in any segment, indicating a leak.

Dye Testing: If the leak is suspected in the pool shell, a dye test can help pinpoint its exact location. This involves using a small amount of dye near the suspected leak and observing its movement. If there’s a leak, the dye will be drawn towards it.

Electronic Detection: Some professionals might use advanced electronic equipment designed to detect sounds or vibrations caused by a leak.

Diving and Inspection: In some cases, especially for deeper pools, divers may be employed. They will inspect the pool in detail, focusing on typical leak-prone areas such as the lights, drains, and seams.

Post Detection – The Repair Phase:

Once the leak or leaks are detected, the next step is the repair. Depending on the severity and location:

  • Small leaks in the liner or pool shell can often be patched without draining the pool.
  • For pipe or plumbing leaks, excavation might be needed.
  • Structural issues or significant damages might require more extensive repairs or even partial pool reconstruction.


Regular maintenance and inspections can prevent minor issues from turning into significant problems. If you notice any signs of a leak in your commercial pool, it’s crucial to act swiftly. Commercial pool leak detection is a specialized job that requires experience, knowledge, and the right tools. Make sure you’re working with a reliable service provider in Arizona who can ensure your pool remains a safe and enjoyable space for all.

By understanding what to expect from the leak detection process, you can ensure timely interventions and potentially save thousands of dollars in long-term damages and water wastage. Remember, an ounce of prevention is worth a pound of cure, especially when it comes to commercial swimming pools in Arizona.
