A slow pool leak can quietly drain your water, your money, and your peace of mind. Many Mesa homeowners lose significant water every week without realizing a leak is the cause. Because of this, early leak detection is one of the most important steps you can take to protect your pool.
Pool leaks are more common than most people think. In fact, even a small crack or failing seal can waste hundreds of gallons over just a few days. Furthermore, the damage often spreads well beyond the pool itself.
At Valley Pool Service, we help homeowners across Mesa, Gilbert, Chandler, and Queen Creek identify and address pool leaks before they turn into costly repairs. In this guide, we will walk you through everything you need to know.
Why Pool Leaks Are a Serious Problem in Arizona
Arizona’s extreme heat puts constant stress on pool materials. Additionally, the dry desert climate causes soil to shift and settle more dramatically than in other states. These conditions make pool leaks both more likely and more damaging.
When water escapes through a crack or a failing fitting, it saturates the soil beneath your pool deck. Over time, this weakens the ground and can cause your deck or pool shell to shift. Moreover, leaks can erode the foundation under surrounding hardscape.
Water loss also forces your pump and filtration system to work harder. Therefore, a hidden leak can shorten the lifespan of your equipment. This means you may face equipment repair costs on top of structural damage.
The Hidden Costs of an Undetected Leak
Many homeowners simply add water when their pool level drops. However, this approach masks the real problem. Meanwhile, the leak continues to grow and causes more damage beneath the surface.
Undetected leaks can lead to higher water bills month after month. They can also cause chemical imbalances, since fresh water constantly dilutes your pool’s carefully balanced chemistry. As a result, you end up spending more on chemicals without ever fixing the root cause.
In the East Valley, where summer water use is already high, a leaking pool makes the situation significantly worse. Catching a leak early through professional leak detection is always the more affordable path forward.
How to Tell If Your Pool Has a Leak
Some water loss is normal, especially during Arizona summers. Evaporation naturally reduces your pool level a bit each day. However, there is a straightforward way to tell the difference between evaporation and an actual leak.
The Bucket Test: A Simple DIY Check
The bucket test is one of the easiest methods pool owners can try at home. First, fill a bucket with pool water and set it on your top pool step. Next, mark the water level inside the bucket and on the pool wall.
Then, wait 24 hours and compare the two levels. If your pool has lost significantly more water than the bucket, you likely have a leak. This simple test gives you a useful starting point before calling a professional.
Keep in mind, however, that the bucket test only tells you a leak exists. It does not tell you where the leak is located. For that, you need trained technicians with the right equipment to find it accurately.
Other Warning Signs to Watch For
Beyond unusual water loss, there are several other signs that something is wrong. Look for wet or soft spots in the soil around your pool or deck. Also, watch for cracks in your pool shell, tile line, or coping.
- Consistently low water levels despite regular refilling
- Unexplained increases in your water bill
- Air bubbles in your pump or return lines
- Loose or shifting pool deck sections
- Algae growth that keeps returning after treatment
- Difficulty maintaining proper water chemistry
If you notice one or more of these signs, contact Valley Pool as soon as possible. Waiting only gives a small problem more time to grow into a larger one.
What Professional Leak Detection Involves
Professional leak detection goes far beyond guesswork. Trained technicians use a combination of methods to pinpoint the exact source of a leak. This saves time, money, and unnecessary digging or repairs.
At Valley Pool Service, our technicians carefully inspect your pool equipment, plumbing lines, fittings, and shell. We check every component that could be allowing water to escape. Additionally, we look at your pump, filter, and return lines as part of a thorough evaluation.
Common Leak Locations in Residential Pools
Pool leaks can originate from several different areas. Understanding where leaks typically occur helps homeowners know what to expect during an inspection.
- Skimmer and main drain: Cracks or failing gaskets here are very common in older pools.
- Return fittings: These fittings can loosen or crack over time, especially with ground movement.
- Pool shell: Gunite and plaster pools can develop cracks from shifting soil or age.
- Plumbing lines: Underground pipes can crack or separate at joints.
- Equipment pad: Pumps, filters, and heaters all have seals and connections that can fail.
In Gilbert and surrounding East Valley communities, soil expansion and contraction from seasonal temperature swings puts extra pressure on these components. Therefore, annual inspections are a wise investment for any pool owner.
Pressure Testing and Dye Testing Explained
Two common professional methods are pressure testing and dye testing. During a pressure test, technicians isolate sections of your plumbing and apply air pressure. If pressure drops, it confirms a leak in that section.
Dye testing uses a small amount of colored dye near suspected leak areas. If the dye gets pulled toward a crack or opening, it visually confirms the leak location. Both methods are non-invasive and highly effective.
These techniques allow our team to find leaks without unnecessary damage to your pool or yard. As a result, repairs are more targeted and far less disruptive to your property.
How Leak Detection Protects Your Pool Investment
Your pool represents a major investment in your home and lifestyle. Protecting that investment means staying ahead of problems before they escalate. Leak detection is a proactive step that keeps repair costs manageable.
When a leak is caught early, repairs are typically straightforward and affordable. However, when a leak goes undetected for months, the resulting damage can require extensive work. In some cases, this includes deck replacement, shell resurfacing, or full plumbing repairs.
Moreover, addressing leaks promptly protects your home’s landscaping and foundation. Water migrating underground can damage irrigation systems, tree roots, and nearby structures. For homeowners in Tempe and Chandler, where properties are often close together, this risk is especially worth considering.
Protecting Your Equipment From Leak-Related Damage
Pool equipment is expensive to replace. Leaks in your plumbing or fittings allow air to enter the system, which causes your pump to run dry or lose prime. Over time, this causes serious wear and premature failure.
Additionally, low water levels force your pump to work overtime. This increases energy consumption and shortens the motor’s lifespan. Therefore, fixing a leak quickly is also a way to protect your equipment investment.
Our Gilbert-based technicians understand the demands Arizona summers place on pool equipment. We can assess your pump, filter, and plumbing as part of any leak inspection. This gives you a complete picture of your pool’s overall condition.

Leak Detection as Part of a Preventive Maintenance Plan
The best time to find a leak is before it causes significant damage. Because of this, we recommend including leak checks as part of your regular pool maintenance routine. A seasonal inspection each year can save you from major expenses down the road.
Valley Pool Service works with homeowners across Gilbert, Mesa, Queen Creek, and beyond to build maintenance plans that fit their schedules and budgets. Whether you need weekly cleaning or a seasonal inspection, we tailor our service to your specific needs.
Furthermore, a consistent maintenance plan helps us spot early warning signs during every visit. When our technicians are familiar with your pool, they can quickly notice changes that indicate a developing problem. This proactive approach keeps your pool in top condition year-round.
When to Call for a Leak Inspection
Do not wait until you see major damage to call for help. There are clear moments when scheduling a professional inspection makes the most sense.
- After a significant weather event or heavy monsoon rain
- When your water bill rises without an obvious explanation
- If you notice cracks in your pool shell or deck
- When your pump loses prime frequently
- If your pool level drops more than a quarter inch per day
- After any major equipment repair or replacement
If any of these situations apply to you, talk with a pool care expert at Valley Pool Service. We can evaluate your pool and give you an honest assessment of what is happening and what your options are.
Frequently Asked Questions About Pool Leak Detection
How do I know if my pool is leaking or just losing water to evaporation?
The bucket test is a reliable starting point. If your pool loses significantly more water than an equal-sized surface of water exposed to the same conditions, a leak is likely. A professional inspection will confirm this and locate the source.
How long does a professional leak detection visit take?
Most inspections take between one and several hours depending on your pool’s size and complexity. Our technicians work efficiently and explain everything they find along the way. You will know exactly what is happening before we leave.
Can a pool leak damage my yard or home foundation?
Yes, it can. Water escaping underground can saturate soil and cause erosion or settling. Over time, this affects your deck, landscaping, and nearby structures. Early leak detection prevents this kind of widespread damage.
Is leak detection covered by homeowners insurance?
Coverage varies by policy and provider. Some policies cover sudden and accidental damage, while others exclude gradual leaks. We recommend reviewing your policy and speaking with your insurance agent for specific guidance.
How often should I have my pool inspected for leaks?
We recommend at least one thorough inspection per year for most residential pools. Additionally, you should schedule an inspection any time you notice unusual water loss or signs of structural change around your pool.
