A leaking pool can quietly cost you hundreds of dollars in water and chemical waste. Many Gilbert homeowners notice their water level dropping and wonder if they should investigate it themselves or call a professional. Knowing when to handle leak detection on your own — and when to bring in expert help — can save you both time and money.
However, pool leaks are not always easy to find. They can hide in your plumbing, shell, fittings, or equipment. Because of this, even a small leak can cause serious damage if left untreated. This guide will walk you through both approaches so you can make the best decision for your pool.
Whether you live in Gilbert, Mesa, Chandler, or Queen Creek, Arizona’s extreme heat puts constant stress on pool materials. That added pressure makes leak detection an important skill for every pool owner to understand.
Why Pool Leaks Are Common in the East Valley
Arizona’s desert climate is tough on pools. Intense UV rays, extreme heat, and dramatic temperature swings cause pool materials to expand and contract over time. As a result, seals crack, fittings loosen, and plumbing joints can begin to fail.
Additionally, our local soil composition in the East Valley can shift slightly due to dry and wet cycles. This ground movement can stress underground plumbing and crack your pool’s shell. Gilbert homeowners deal with these conditions every season, making leaks more common than many people expect.
Furthermore, older pools with aging equipment are especially vulnerable. Even a well-maintained pool can develop a slow leak that goes unnoticed for weeks. The sooner you identify the source, the easier and less expensive the repair will be.
Signs Your Pool May Have a Leak
First, check how much water your pool is losing each day. Some water loss is normal due to evaporation, especially during hot Arizona summers. However, losing more than a quarter inch per day could signal a leak.
Also, watch for these common warning signs:
- Consistently dropping water levels beyond normal evaporation
- Wet or soggy spots in the yard near the pool equipment pad
- Cracks or gaps in the pool shell, tile line, or coping
- Higher-than-usual water bills without an obvious explanation
- Constantly unbalanced water chemistry despite regular treatment
- Air bubbles coming from your return jets
If you notice one or more of these signs, it is time to investigate further. The next step is deciding whether to start with a DIY approach or call a professional right away.
The Bucket Test: A Simple DIY Starting Point
The bucket test is the most popular DIY method for confirming a pool leak. It is easy to perform and requires no special tools. Therefore, it is a great first step before spending money on professional services.
How to Perform the Bucket Test
First, fill a five-gallon bucket with pool water. Next, place the bucket on the first or second step of your pool so it sits partially submerged. Then, mark the water level inside the bucket and the pool water level on the outside of the bucket.
Let the bucket sit for 24 to 48 hours without running the pool equipment. After that, compare the two levels. If the pool water dropped more than the water inside the bucket, evaporation is not the culprit — you likely have a leak.
This simple test costs nothing and gives you a clear answer. However, it does not tell you where the leak is located. That is where things get more complicated.
Other Basic DIY Checks
After confirming a leak, you can also visually inspect your pool equipment. Look closely at your pump, filter, heater, and valves for drips or moisture. Moreover, check the pool shell for visible cracks, especially around returns, skimmers, and lights.
Also inspect the area around your equipment pad. Wet concrete or damp soil near the pad often points to a plumbing leak. These visual checks are easy and can help narrow down the source before a professional arrives.
On the other hand, if you cannot find anything obvious, it is time to consider professional leak detection. Leaks in underground plumbing or behind walls are nearly impossible to locate without the right equipment.
What Professional Leak Detection Involves
Professional leak detection goes far beyond what the average homeowner can do alone. Trained pool technicians use specialized tools and techniques to pinpoint leaks quickly and accurately. Because of this, they can often find problems in minutes that would take a homeowner days to locate.
Pressure Testing and Dye Testing
Pressure testing involves isolating sections of your pool’s plumbing and applying air or water pressure. A drop in pressure reveals exactly which line is leaking. This method is highly effective for underground pipes and return lines.
Dye testing is another precise technique. A professional injects a small amount of colored dye near suspected leak points. If the dye is pulled toward a crack or gap, that area confirms the leak. Additionally, dye testing works well around fittings, lights, and skimmers.
These methods require skill and experience to use correctly. Attempting them without training can damage your plumbing or give inaccurate results. Therefore, professional service is strongly recommended for anything beyond a basic visual inspection.
Electronic Leak Detection Equipment
Some pool service companies use electronic listening devices to detect the sound of water escaping underground pipes. This technology is extremely useful for locating leaks beneath decks or inside walls. As a result, technicians can pinpoint a leak without tearing up your yard unnecessarily.
In the Gilbert and Chandler area, professional leak detection often saves homeowners from expensive and unnecessary excavation. Finding the exact leak location first means a much smaller, more targeted repair. That translates directly to lower repair costs for you.
DIY vs Professional: Which Is Right for You?
The honest answer depends on what you find during your initial checks. DIY methods work best for confirming that a leak exists and performing basic visual inspections. They cost nothing and give you useful information.
However, once you confirm a leak but cannot find the source, professional help is almost always the smarter choice. Guessing at underground plumbing or probing your pool shell incorrectly can make the problem worse. Moreover, wasted time means more water loss and higher water bills.
For homeowners in Gilbert, Mesa, and the surrounding East Valley, a professional inspection can often pay for itself in water savings alone. In addition, catching a small leak early prevents it from growing into a much more expensive structural repair.
If you are unsure where to start, contact Valley Pool and our experienced Gilbert technicians will help you figure out the best next step for your specific situation.
When to Skip DIY Entirely
Some situations call for professional help right away. Skip the DIY approach if you notice any of the following:
- Visible cracks in the pool shell that are growing or spreading
- Sudden large drops in water level overnight
- Bubbling or gurgling sounds from your plumbing lines
- Sinkholes or soft spots in the ground near your pool
- Water appearing inside your home near pool plumbing
These signs suggest a serious and potentially dangerous leak. In these cases, acting quickly is essential. Call a pool professional immediately to assess the situation and prevent further damage.

Frequently Asked Questions About Pool Leak Detection
How much water loss is normal for a Gilbert pool?
Some evaporation is normal, especially during our hot Arizona summers. Generally, losing up to a quarter inch of water per day is considered normal evaporation. However, anything beyond that warrants a closer look using the bucket test or a professional inspection.
Can I use food coloring instead of professional dye for dye testing?
Some homeowners try this, and it can give a rough indication near visible cracks. However, professional dye is formulated to behave more precisely in water. Therefore, results from food coloring are far less reliable and may lead you to the wrong conclusion.
How long does a professional pool leak inspection take?
In most cases, a trained technician can complete a thorough inspection in a few hours. However, complex leaks in underground plumbing may require additional time or follow-up testing. Your technician will give you a clear timeline before work begins.
Will leak detection damage my pool or yard?
Modern professional techniques are designed to be minimally invasive. Dye testing, pressure testing, and electronic detection rarely require any digging. If excavation is needed, your technician will discuss that option with you in advance.
Is it worth fixing a small pool leak right away?
Yes, absolutely. Even a slow leak can waste a significant amount of water over weeks and months. Additionally, small leaks often grow larger over time, especially under Arizona’s heat and ground conditions. Early repairs are almost always less expensive than waiting.
