Noticing your pool water level dropping faster than usual? You may have a leak. Leak detection is one of the most important services a pool owner can request, especially here in Gilbert, AZ, where pools run year-round. Finding a leak early can save you from serious water loss and expensive repairs.
However, many homeowners are not sure what leak detection actually involves. The process can feel mysterious if you have never gone through it before. Therefore, this guide walks you through exactly what to expect, from the first signs of a leak to the final repair.
Valley Pool Service works with homeowners across Gilbert and the greater East Valley to locate and resolve pool leaks quickly. We use a thorough, professional approach to protect your pool and your wallet.
Why Pool Leaks Are a Serious Problem in Arizona
Arizona’s heat puts constant demand on your pool. Because of this, even a small leak can lead to major water loss in a short time. In Gilbert, Mesa, and Chandler, water bills can climb quickly when a pool is losing water undetected.
Additionally, leaks do not just waste water. They can erode the ground around your pool shell, damage your equipment pad, and undermine your pool deck. Over time, this structural damage becomes far more costly than the leak itself.
Furthermore, low water levels force your pump to work harder. This extra strain can burn out your equipment prematurely. Therefore, catching a leak early is always the smarter financial move.
How Do You Know If Your Pool Is Leaking?
Some water loss is normal due to evaporation and splash-out. However, if your pool loses more than a quarter inch of water per day, that is a red flag. Arizona summers are hot, but evaporation alone rarely accounts for dramatic drops.
Also, watch for these warning signs:
- Cracks or gaps around fittings, returns, or the skimmer
- Wet or soggy spots in your yard near the pool
- Equipment that runs dry or loses prime frequently
- Rising water bills without a clear explanation
- Needing to add water to your pool more than once a week
If you notice any of these signs, it is time to schedule a professional leak detection inspection right away.
The Bucket Test: A Simple Starting Point
Before calling a professional, many homeowners try the bucket test. This simple method helps you distinguish between evaporation and an actual leak. It requires nothing more than a bucket and a marker.
How to Perform the Bucket Test
First, fill a bucket with pool water and set it on your pool step. Next, mark the water level inside the bucket and on your pool wall. Then, wait 24 to 48 hours without using the pool or running the auto-fill.
After that period, compare the two water levels. If your pool lost significantly more water than the bucket, you likely have a leak. On the other hand, if the levels dropped by the same amount, evaporation is probably the culprit.
Moreover, you can run the test twice — once with the pump on and once with it off. This helps narrow down whether the leak is in your plumbing lines or the pool shell itself. A professional technician will use this information as a helpful starting point.
What Professional Leak Detection Involves
Once you contact a pool service company, a trained technician will come to your property and conduct a thorough inspection. Professional leak detection goes far beyond what a homeowner can do alone. Technicians use specialized tools and tested methods to find leaks with precision.
In addition, a good technician will inspect every part of your pool system — not just the obvious spots. Leaks can originate in unexpected places, so a comprehensive approach is essential.
Pressure Testing Your Plumbing Lines
One common method is pressure testing. The technician isolates sections of your plumbing and pressurizes them to check for drops. A pressure drop indicates a leak somewhere in that line. This method is highly effective for identifying underground plumbing issues that are not visible from the surface.
Because underground pipes are buried beneath your deck or yard, locating them requires careful testing. However, modern pressure equipment makes this process much more accurate than guesswork. As a result, technicians can often pinpoint the problem area without unnecessary digging.
Dye Testing for Shell and Fitting Leaks
Dye testing is another widely used technique. The technician injects a small amount of dye near suspected leak points, such as cracks, fittings, lights, or returns. If the dye is pulled toward a crack or gap, it visually confirms a leak in that location.
This method is especially useful for pool shells and equipment fittings. Additionally, it is non-invasive and easy to perform in any pool size. For example, a light niche that has lost its seal is a common source of leaks in many Gilbert homes.
Electronic Leak Detection Equipment
Some leaks require more advanced tools. Electronic listening devices can detect the sound of water escaping underground pipes. This technology allows technicians to locate leaks in buried lines without tearing up your entire deck or yard.
Furthermore, in communities like Queen Creek and Gilbert Ranch, where pools often have extensive underground plumbing runs, electronic detection is especially valuable. It saves time, reduces disruption, and leads to more accurate repairs.
Common Sources of Pool Leaks in Gilbert
Pool leaks can originate from many different places. Understanding the most common sources helps you stay observant between service visits. Moreover, it helps you give useful information to your technician when they arrive.
- Skimmer connections: The joint between the skimmer and pool shell is a frequent leak point, especially as the shell shifts over time.
- Return line fittings: These fittings push water back into the pool. They can crack or loosen with age and temperature changes.
- Pool light housings: The conduit and niche around pool lights often develop leaks as sealants degrade.
- Main drain: Older main drains can develop cracks or seal failures at the bottom of the pool.
- Plumbing joints: Underground joints and unions are vulnerable to shifting soil and pressure changes common in Arizona’s desert climate.
- Pool shell cracks: Surface cracks can allow water to seep out, especially in older plaster or pebble finishes.
Because Arizona’s soil can expand and contract with temperature swings, pool structures in the East Valley face unique stress. Therefore, regular inspections are a smart investment for any Gilbert homeowner.
What Happens After the Leak Is Found?
Once the leak is located, your technician will explain the findings clearly. At Valley Pool Service, we walk every homeowner through what we found and what options are available. You should never feel confused or pressured after a leak detection visit.
Additionally, the repair approach depends on where the leak is located. Some repairs are simple and completed during the same visit. Others require more involved work, such as accessing underground plumbing or patching a section of pool shell.
Simple Repairs vs. More Involved Fixes
For example, a loose fitting or a small surface crack may be addressed relatively quickly. However, a broken underground pipe or a compromised main drain may require more time and excavation. Your technician will outline all options and help you understand the scope before any work begins.
Furthermore, it is always better to address the repair promptly. Delaying a known leak allows damage to worsen and water loss to continue. In the long run, acting quickly almost always costs less than waiting.

Frequently Asked Questions About Pool Leak Detection
How long does a leak detection inspection take?
Most leak detection visits take anywhere from one to a few hours, depending on the size of your pool and the complexity of the system. However, more extensive testing may take longer if underground plumbing is involved.
Can I use my pool during a leak detection visit?
In most cases, the pool should remain still and unused during testing. This allows technicians to observe accurate water level changes and apply dye testing properly. Your technician will let you know what to expect before they begin.
Is all water loss a sign of a leak?
Not always. Evaporation, splash-out, and backwash can all contribute to water loss. However, if your pool consistently loses more than a quarter inch per day, a leak is likely. The bucket test is a good first step before calling a professional.
What if the leak is underground?
Underground leaks are common in older pools and in areas with shifting soil, like many neighborhoods in Gilbert and the East Valley. Technicians use pressure testing and electronic detection tools to locate these leaks without unnecessary excavation.
How soon should I fix a confirmed pool leak?
As soon as possible. Even a modest leak can waste a significant amount of water over days and weeks. Additionally, ongoing leaks can damage your pool structure, equipment, and surrounding landscaping. Prompt action protects your investment.
