Losing pool water is one of the most frustrating problems a homeowner can face. You refill the pool, and a few days later the water level is low again. Leak detection is the process of finding exactly where that water is going — and it matters more than most people realize.
In Gilbert, AZ, pools work hard all year long. Because of this, even a small leak can lead to big damage if you ignore it. Soil erosion, rising water bills, and equipment failure are all possible consequences of an undetected pool leak.
Fortunately, catching a leak early makes a real difference. The Valley Pool Service team helps Gilbert homeowners identify and resolve pool leaks before they turn into costly repairs. In this guide, we will walk you through everything you need to know.
Why Pool Leak Detection Matters in Gilbert
Arizona summers are intense. Your pool is under constant pressure from heat, heavy use, and shifting soil. Therefore, leaks can develop in places you would never think to look.
Most homeowners assume water loss is just evaporation. However, evaporation and an actual leak can look very similar at first glance. Knowing the difference can save you hundreds of dollars in wasted water and unnecessary repairs.
In communities like Chandler, Mesa, and Queen Creek, pool technicians see similar issues. The desert climate causes ground movement that stresses pool shells and plumbing over time. As a result, even well-built pools can develop cracks or fitting failures.
How Much Water Loss Is Normal?
Evaporation is normal, especially in the Arizona heat. On average, pools can lose a noticeable amount of water each week through evaporation alone. However, if your water level drops more than expected or you notice wet spots around the pool deck, something else may be happening.
Additionally, if you are constantly adding water to maintain the level, that is a warning sign. A professional leak detection inspection can confirm whether evaporation or a real leak is the culprit.
The Bucket Test: A Simple DIY Check
Before calling a technician, you can run a simple bucket test at home. First, fill a bucket with pool water and set it on a pool step. Next, mark the water level inside the bucket and on the pool wall. Then, wait 24 to 48 hours without running the pool equipment.
After the waiting period, compare the two levels. If the pool lost significantly more water than the bucket, you likely have a leak. This quick test helps you decide whether to move forward with a professional inspection.
Common Causes of Pool Leaks in the East Valley
Leaks can come from many different sources. Moreover, they are not always obvious. Here are the most common causes our team finds in Gilbert-area pools.
- Shell cracks: Ground movement and temperature changes can crack the plaster or gunite shell of your pool.
- Fitting and valve leaks: Fittings around return jets, skimmers, and drains can loosen or degrade over time.
- Plumbing leaks: Underground pipes can crack or separate, making them especially difficult to locate without professional equipment.
- Light housing leaks: Pool lights are a common and often overlooked source of leaks.
- Equipment pad leaks: Pumps, filters, and heaters can all develop leaks at connection points.
Because the East Valley soil shifts with seasonal temperature swings, plumbing stress is a year-round concern. Furthermore, older pools in neighborhoods across Gilbert and Tempe are especially vulnerable to these issues.
Signs You May Have a Pool Leak
Not every leak is visible. In fact, many leaks go unnoticed for weeks before a homeowner calls for help. Watch for these warning signs.
- Water level drops consistently, even without heavy splash-out
- Wet or soggy ground around the pool equipment pad
- Unusually high water bills
- Air bubbles coming from the return jets
- Pool chemicals seem to deplete faster than usual
- Cracks or separation in the pool deck or coping
If you notice any of these signs, it is time to take action. Contact the Valley Pool team to schedule a professional inspection before the problem gets worse.
How Professional Leak Detection Works
Professional leak detection goes far beyond the bucket test. Trained technicians use specialized tools and methods to pinpoint exactly where water is escaping. As a result, repairs are targeted and efficient.
Our technicians start with a thorough visual inspection of the pool shell, equipment, fittings, and surrounding deck. Then, we move on to more advanced testing methods depending on what we find.
Pressure Testing the Plumbing
One of the most effective leak detection methods is pressure testing. This involves isolating sections of your pool’s plumbing and applying air or water pressure to identify where the line is failing. It helps locate underground leaks that are otherwise invisible without digging.
Additionally, pressure testing can confirm which specific line is losing pressure. This saves time and money because technicians know exactly where to dig or repair, rather than guessing.
Dye Testing for Structural Leaks
Dye testing is a simple but powerful technique. A technician injects a small amount of colored dye near a suspected crack or fitting. If the dye is pulled toward the surface and disappears, water is escaping from that point.
This method is especially useful for checking light housings, skimmer seals, and visible cracks in the shell. Furthermore, it is non-invasive and quick to perform during an inspection visit.
Electronic Leak Detection Equipment
For harder-to-find leaks, professionals use electronic listening devices. These tools detect the sound of escaping water through pipes and soil. Therefore, they allow technicians to locate underground plumbing leaks without unnecessary excavation.
This technology is particularly valuable in established neighborhoods in Gilbert and surrounding areas like San Tan Valley, where pools may have older plumbing systems buried deep beneath landscaping.
What Happens After a Leak Is Found?
Once our team identifies the source of the leak, we walk you through your repair options clearly and honestly. We explain what needs to be done, why it matters, and what each option involves. You always have the final say.
Some leaks are minor and require only a simple sealant or fitting replacement. Others, like a cracked shell or broken underground pipe, require more involved repairs. However, addressing the issue promptly always costs less than waiting.
After repairs are complete, we recommend a follow-up check to confirm the leak is fully resolved. Moreover, we can help you set up a regular maintenance schedule to catch potential problems early in the future.
Protecting Your Pool Long-Term
The best way to prevent leaks from becoming major problems is consistent pool care. Regular inspections allow our team to spot early signs of wear before they turn into expensive repairs. Additionally, proper water chemistry plays a role in protecting your pool’s plaster and fittings from deterioration.
We encourage every homeowner in the East Valley to have their pool inspected at least once a year. For older pools or pools with a history of issues, more frequent checks are a smart investment.
Frequently Asked Questions About Pool Leak Detection
How do I know if my pool is leaking or just evaporating?
The bucket test is a great starting point. If your pool loses significantly more water than the bucket over 24 to 48 hours, a leak is likely. A professional inspection will give you a definitive answer.
Can I use the pool while leak detection is being performed?
In most cases, yes. However, some tests require the pool to be running or at rest, depending on what is being checked. Your technician will let you know what to expect before starting.
How long does a professional leak detection inspection take?
A typical inspection takes a few hours, depending on the pool size and complexity of the issue. If advanced methods like pressure testing or electronic detection are needed, it may take longer.
Are pool leaks covered by homeowners insurance?
Coverage depends on your specific policy and the cause of the leak. Sudden damage may be covered, while gradual leaks often are not. We recommend contacting your insurance provider directly for guidance.
What if the leak is in my underground plumbing?
Underground plumbing leaks require pressure testing and sometimes electronic detection to locate. Once found, our team will explain the repair options and what the process involves. We always aim to minimize disruption to your yard and landscaping.
