Losing water in your pool is frustrating—and costly. However, not every pool owner realizes that a slow leak could be draining hundreds of gallons each week. In Gilbert, AZ, leak detection is one of the most important services you can schedule to protect your pool and your wallet.
Many homeowners assume evaporation is the culprit. In fact, Arizona’s intense heat does cause noticeable water loss. However, if you are refilling your pool more than once a week, a leak may be to blame. The sooner you catch it, the better.
So when is the best time of year to schedule a leak detection service in Gilbert? The answer depends on your pool’s condition, the season, and what signs you are already seeing. Let’s walk through everything you need to know.
Why Pool Leak Detection Matters in Gilbert, AZ
Gilbert homeowners deal with some of the harshest pool conditions in the country. The desert climate pushes pools hard from spring through fall. Because of this, equipment, plumbing, and surfaces take on a lot of stress throughout the year.
A leak does more than waste water. It can erode the soil beneath your pool shell, damage surrounding decking, and throw off your water chemistry. Over time, even a small leak leads to bigger, more expensive problems.
Additionally, wasted water in the East Valley means higher utility bills. With water costs rising across Maricopa County, finding and fixing leaks quickly makes both environmental and financial sense.
Common Causes of Pool Leaks in the East Valley
Leaks can come from several sources. Therefore, a proper diagnosis is essential before any repair begins. Here are the most common culprits our Gilbert pool technicians encounter:
- Plumbing line cracks – Ground shifting and soil movement can crack underground pipes.
- Pump and filter fittings – Connections loosen over time, especially with heat expansion and contraction.
- Pool shell cracks – Plaster or fiberglass can crack from ground movement or age.
- Skimmer and return fittings – These are high-wear areas prone to seal failure.
- Light fixture housings – Poor seals around pool lights are a surprisingly common leak source.
Furthermore, leaks in the equipment pad area are sometimes easier to spot. However, underground plumbing leaks often require specialized tools to locate accurately.
The Best Seasons for Pool Leak Detection in Gilbert
Timing matters when it comes to leak detection. Some seasons make the process easier and more accurate. Others can complicate the results. Let’s break it down by season for Gilbert and the surrounding East Valley.
Spring: The Ideal Window
Spring is widely considered the best time for leak detection in Gilbert. The weather is mild, and pool use is just beginning to ramp up. Because of this, any unusual water loss stands out clearly against the moderate evaporation rates of March through May.
Additionally, catching a leak in spring means you can get it repaired before the summer swim season begins. Nobody wants to discover a plumbing issue in July when temperatures hit 110°F and your pool is in constant use.
Moreover, pool service teams tend to have more flexibility in spring. Scheduling is generally easier before the peak summer rush hits across Mesa, Chandler, and Gilbert.
Early Summer: Still a Smart Choice
Early summer—think late May through June—is also a practical time for leak detection. Your pool is now in full use, which actually helps. Higher usage makes abnormal water loss more obvious and easier to track.
However, summer also brings extreme evaporation. Therefore, it becomes harder to separate natural water loss from a genuine leak. A trained technician will use the bucket test or pressure testing to isolate the source accurately.
If you notice your water level dropping faster than usual as summer begins, do not wait. Contact a pool professional right away to rule out a serious leak before the heat of July and August arrives.
Fall: Another Strong Option
Fall is an underrated time for pool leak detection in the East Valley. As temperatures drop after September, evaporation rates decrease. This makes it easier to measure true water loss without the distortion of summer heat.
Additionally, fall is when many Gilbert and Queen Creek homeowners transition their pools from heavy summer use to lighter maintenance. This is a natural moment to inspect everything and address any lingering issues before winter.
In short, if you missed the spring window, fall gives you a second great opportunity to schedule leak detection before the new year.
Winter: Possible, But Less Ideal
Arizona winters are mild compared to most of the country. Therefore, pools in Gilbert remain usable year-round. However, winter is generally the least ideal time for leak detection for one key reason: usage drops.
Lower usage means less data to work with. Also, the cooler months bring slightly higher moisture in the air, which can affect evaporation baselines. On the other hand, if you suspect an active leak in winter, you should still have it inspected. A leak does not take a season off.
How to Tell If Your Pool Has a Leak
Before calling a pool professional, it helps to do a quick check at home. The bucket test is the simplest method most homeowners can perform on their own.
The Bucket Test: A Simple DIY Check
First, fill a bucket with pool water and place 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. Finally, compare the two levels.
If the pool lost significantly more water than the bucket, you likely have a leak. However, similar levels suggest normal evaporation. This simple test gives you a starting point before a professional inspection.
Also, watch for these additional warning signs around your pool:
- Wet or soft spots in the soil around the pool deck
- Cracks in the deck or coping
- Needing to add water more than twice a week
- Unexplained increases in your water or chemical bills
- Air bubbles returning through the jets when the pump runs
- Equipment that runs dry or loses prime frequently
Moreover, if your water chemistry is constantly off even with regular treatment, a slow leak may be diluting your chemicals faster than expected.
Professional Leak Detection: What to Expect
A professional leak detection service goes far beyond the bucket test. Our Valley Pool technicians use pressure testing and dye testing to pinpoint exactly where water is escaping.
Pressure testing involves isolating sections of your plumbing lines and applying controlled air or water pressure. This method quickly reveals whether a line is holding or losing pressure. Dye testing is used near fittings, lights, and shell cracks to see where water is being pulled through a surface.
Furthermore, our technicians carefully inspect your equipment pad for wet fittings, loose unions, and failing seals. Many leaks start at the equipment level and are caught before any digging is necessary.

Frequently Asked Questions About Pool Leak Detection
How much water loss is normal in a Gilbert pool?
In Arizona, pools can lose a quarter to half an inch of water per day to evaporation during summer. However, if you are losing more than that consistently, it may indicate a leak. A bucket test or professional inspection will confirm the source.
Can a pool leak fix itself?
In rare cases, minor plaster cracks can seal with calcium deposits over time. However, most leaks do not self-heal. In fact, they tend to worsen as soil shifts and pressure continues. Therefore, it is always better to have a suspected leak professionally inspected.
How long does a professional leak detection take?
Most leak detection visits take a few hours, depending on the size of your pool and the complexity of the plumbing. If the leak is straightforward, our team can often identify and repair it during the same visit.
Is leak detection covered by homeowner’s insurance?
Coverage varies by policy and the cause of the leak. We recommend contacting your insurance provider directly. Meanwhile, our technicians can provide documentation of the findings to support your claim if needed.
What happens if a pool leak goes untreated?
An untreated leak can erode the soil beneath your pool, damage your deck, strain your equipment, and lead to structural issues over time. Additionally, you will continue wasting water and money every single day the leak goes unaddressed.
