A small pool leak can quietly cause big damage. Many Gilbert homeowners notice their water level dropping and assume it’s simply evaporation. However, a hidden leak can waste thousands of gallons and silently harm your pool’s structure, equipment, and surrounding landscaping.
Professional leak detection helps you find the source fast — before costs spiral out of control. Because of this, more East Valley homeowners are skipping the guesswork and calling a trusted pool service team instead.
At Valley Pool Service, we understand how frustrating a mystery water loss can be. Therefore, our experienced Gilbert technicians use proven methods to locate leaks accurately and recommend the right repair plan for your pool.
How Do You Know Your Pool Is Leaking?
Not every drop in water level signals a leak. However, there are clear signs that point to something more serious than evaporation. Knowing what to watch for can save you time and money.
Common Signs of a Pool Leak
First, watch for a water level drop that exceeds normal evaporation. In Gilbert’s hot summer months, pools can lose some water naturally each week. On the other hand, if you’re adding water far more frequently than usual, that’s a warning sign.
Additionally, look for these indicators around your pool:
- Wet or soggy soil near the pool equipment pad or pool walls
- Cracks in the pool deck or shifting around the coping
- Unexplained increases in your water or chemical bills
- Air in the pump or equipment running louder than normal
- Algae growth that returns quickly despite regular chemical treatments
Furthermore, if your pool’s auto-fill valve runs constantly, that’s a strong sign you have a leak somewhere in the system. Many homeowners in Mesa, Chandler, and Gilbert have discovered leaks this way before any visible damage appeared.
The Bucket Test: A Simple First Step
The bucket test is a basic method homeowners can try at home. Simply fill a bucket with pool water and set it on a pool step. Mark the water level inside the bucket and on the pool wall. Then check both levels after 24 hours.
If the pool loses noticeably more water than the bucket, you likely have a leak. Next, call a professional to pinpoint the exact location before the problem worsens.
Why Professional Leak Detection Makes a Difference
Many homeowners try to locate leaks themselves. However, pool leaks are often hidden inside plumbing lines, behind shell walls, or beneath the pool deck. Without the right tools, DIY searching can cause more damage than the leak itself.
Professional leak detection uses specialized equipment to find problems quickly and accurately. As a result, repairs are targeted — meaning less disruption to your yard, deck, and budget.
Pressure Testing and Dye Testing Explained
Two common methods professionals use are pressure testing and dye testing. Pressure testing involves sealing sections of the plumbing and applying air or water pressure to identify where the line fails. This method works well for underground pipe leaks.
Dye testing is a simpler visual method. A technician releases a small amount of colored dye near suspected leak points. If the dye gets pulled through a crack or gap, the leak location is confirmed. In addition, this method is non-invasive and very effective around fittings, returns, and skimmers.
Electronic Leak Detection Technology
Moreover, advanced pool technicians use electronic listening devices and sonar equipment. These tools detect the sound of water escaping through cracks in underground pipes. Because of this technology, professionals can locate leaks without digging up your entire yard.
This approach is especially valuable in communities like Gilbert, Queen Creek, and San Tan Valley, where pools often sit on expansive soil that shifts seasonally and stresses underground plumbing.
The Real Cost of Ignoring a Pool Leak
Ignoring a pool leak rarely makes it better. In fact, small leaks almost always grow over time. Additionally, the secondary damage they cause can far exceed the original repair cost.
Structural and Equipment Damage
Water leaking beneath a pool shell or deck can erode the soil underneath. Over time, this causes the deck to crack, shift, or settle unevenly. Furthermore, a leak near your equipment pad can damage your pump, filter, or heater through constant moisture exposure.
In Gilbert’s intense summer heat, equipment already works hard to keep your pool running. Therefore, adding moisture-related stress accelerates wear and can lead to premature equipment failure.
Rising Water and Chemical Costs
A leaking pool constantly needs refilling. Meanwhile, every time you add fresh water, your chemical balance gets disrupted. As a result, you end up spending more on chemicals to re-balance pH, alkalinity, and sanitizer levels.
Many Chandler and Gilbert homeowners are surprised to learn how much a slow leak costs them in water bills alone over a single summer season. Getting it fixed early almost always saves money in the long run.
Where Pool Leaks Most Commonly Occur
Leaks can develop in several different areas of a residential pool. Knowing the most common locations helps homeowners understand what a technician is looking for during an inspection.
Plumbing Lines and Fittings
Underground plumbing is one of the most frequent sources of leaks. Pipes can crack due to ground movement, freeze damage (even in Arizona, rare cold snaps matter), or simply aging materials. Additionally, fittings at the pump, filter, and heater connections can loosen or degrade over time.
Skimmers and Return Lines
The skimmer — the opening on the pool wall that pulls water into the filtration system — is a common leak point. The seal between the skimmer and the pool shell can deteriorate, especially in older pools. Return jets and their fittings are also frequent culprits.
Pool Shell Cracks and Plaster
Gunite and plaster pools can develop cracks over the years. In the Arizona heat, plaster expands and contracts with temperature swings. Furthermore, ground movement in the East Valley’s clay-heavy soils puts stress on pool shells. Even hairline cracks can allow significant water loss over time.
If you notice rough or flaking plaster, that’s a good reason to schedule a professional inspection. Contact the Valley Pool team to get a thorough assessment of your pool’s condition.

We believe every homeowner deserves straightforward answers — not confusing technical jargon. Therefore, we explain what we found, why it matters, and what it takes to fix it. You always have the final say on how to proceed.
Leak Detection in Gilbert’s Unique Pool Environment
Gilbert and the broader East Valley present specific challenges for pool owners. The region’s expansive clay soils shift throughout the year as moisture levels change. As a result, even well-built pools experience ground movement that stresses plumbing and shells.
Additionally, Arizona’s extreme summer temperatures push pool equipment to its limits. Pumps, filters, and plumbing materials degrade faster in heat. Meanwhile, UV exposure breaks down gaskets and seals around fittings more quickly than in cooler climates.
Communities like Ahwatukee, Gilbert, Mesa, and Chandler all share these conditions. Because of this, proactive leak detection is especially smart for Arizona pool owners — not just reactive when the damage is already done.
Frequently Asked Questions About Pool Leak Detection
How much water loss is normal for an Arizona pool?
In Gilbert’s dry summer heat, pools typically lose some water each week through evaporation. However, if your water level drops significantly more than that, especially without heavy splash-out or backwashing, a leak is likely. A professional inspection can confirm the cause quickly.
Can I fix a pool leak myself?
Minor surface repairs, like patching a visible crack in plaster, are possible for some homeowners. However, most leaks originate in plumbing or fittings that require professional tools to locate and repair. Attempting complex repairs without experience often leads to larger problems.
How long does a leak detection inspection take?
Most professional leak detection visits take a few hours, depending on the pool’s size and the complexity of the issue. Plumbing pressure tests and electronic detection may take additional time. Your technician will give you a realistic timeframe before starting.
Will leak detection damage my yard or deck?
Modern leak detection methods are designed to minimize disruption. Electronic and pressure testing typically requires little to no digging. If excavation is needed to access a pipe, we will discuss that with you beforehand and explain the scope clearly.
How soon should I act if I suspect a leak?
Act as soon as possible. Even a slow leak wastes significant water over days and weeks. Furthermore, delayed repairs allow structural damage to compound. The sooner you schedule a professional inspection, the lower your overall repair cost is likely to be.
