A leaking pool can cost you far more than a higher water bill. In fact, a slow pool leak can quietly damage your deck, erode your yard, and stress your equipment for weeks before you even notice. Leak detection is the process of finding exactly where your pool is losing water — and it is one of the most important services a Gilbert homeowner can schedule.
However, many pool owners wait too long. They assume the water loss is just evaporation, especially in the dry Arizona heat. Meanwhile, the real problem continues to grow beneath the surface.
This guide will help you understand the warning signs, the right timing, and why professional leak detection in Gilbert, AZ is always worth it.
How Much Water Loss Is Normal in Gilbert?
Arizona pools lose water every single day. Because of this, it can be hard to tell the difference between normal evaporation and an actual leak. Gilbert sits in the heart of the Sonoran Desert, where summer temperatures regularly push past 110°F.
Under those conditions, evaporation is real. However, there is a limit to how much loss is normal.
The Bucket Test: A Simple First Step
Before calling a professional, you can run a simple bucket test at home. Fill a bucket with pool water and set it on the first or second step of your pool. Mark the water level inside the bucket and on the pool wall. Then, wait 24 hours without running the pool.
If the pool loses significantly more water than the bucket, you likely have a leak. On the other hand, if both levels drop equally, evaporation is probably the cause.
This quick test gives you a useful starting point. Additionally, it helps you have a more informed conversation with your pool technician when you call.
Warning Signs You Need Pool Leak Detection
Some leaks are subtle. Others show up in obvious ways. Therefore, knowing what to look for can help you catch the problem before it gets expensive.
Your Water Bill Has Spiked
A sudden increase in your water bill is one of the clearest signs of a pool leak. You may be refilling your pool more often than usual without realizing how much water you are adding. Because of this, it pays to track your refill habits from month to month.
Many Gilbert and Chandler homeowners are surprised to discover how much a slow leak can add to their monthly utility costs. Furthermore, the longer the leak goes undetected, the worse that number gets.
Wet or Soft Spots Around the Pool Deck
If you notice wet soil, soft patches of grass, or soggy areas around your pool deck, water may be escaping underground. This is especially common near return lines, skimmers, and the main drain. Moreover, these wet spots can destabilize your deck over time.
In Mesa, Queen Creek, and other East Valley communities, shifting desert soil can also put stress on pool plumbing. As a result, even newer pools are not always immune to leak issues.
You Are Adding Water More Than Twice a Week
Needing to top off your pool once or twice a week during peak summer heat is fairly normal. However, if you find yourself adding water every day or two, that is a red flag. Additionally, watch for visible drops in water level that happen overnight when evaporation slows.
Cracks in the Shell or Deck
Visible cracks in your pool’s plaster, tile, or surrounding deck can allow water to seep out. Arizona’s intense heat and dry conditions cause materials to expand and contract repeatedly. Therefore, even small cracks deserve a professional look.
Chemical Imbalance You Cannot Explain
A leaking pool constantly introduces fresh, untreated water into your pool. This dilutes your chemicals and throws off your water balance. If you are struggling to maintain proper pH, chlorine, or alkalinity levels — and you cannot explain why — a leak may be the reason.
In addition, constantly adding chemicals to compensate adds up quickly in cost and effort.
When Is the Best Time to Schedule Leak Detection?
The short answer is: as soon as you suspect a problem. However, there are certain times of year when scheduling early makes a big difference for Gilbert pool owners.
Before Summer Swim Season
Spring is the ideal time to schedule a leak inspection. You want your pool fully functional before June arrives. Therefore, catching a leak in March or April gives you plenty of time for repairs before the hottest months.
Many Tempe and Gilbert homeowners schedule their spring pool checkup and ask for a leak assessment at the same time. This is a smart, efficient approach.
After a Hard Winter or Heavy Rain
While Arizona winters are mild, temperature swings can still stress pool equipment and plumbing. Additionally, heavy rainfall can shift soil and put pressure on underground pipes. After any unusual weather, it is a good idea to have your pool inspected.
When Equipment Problems Appear
Sometimes a leak is connected to your equipment, not just the shell. If your pump is losing prime, your filter pressure is inconsistent, or your auto-fill valve runs constantly, these can all signal a leak somewhere in the system. Moreover, equipment issues and leaks often appear together.
If you are seeing any of these signs, contact Valley Pool to schedule a professional inspection and get ahead of the problem before it grows.
What Happens During a Professional Leak Detection Visit?
Professional leak detection goes well beyond the bucket test. A trained pool technician uses specialized tools and techniques to locate the exact source of water loss. This saves you from guessing — and from paying for unnecessary repairs.
Pressure Testing the Plumbing
One common method involves pressure testing your pool’s plumbing lines. The technician seals off sections of pipe and introduces air or water pressure. Next, they check for pressure drops that indicate a crack or loose fitting underground.
Dye Testing
Dye testing is another useful tool. A small amount of dye is released near suspected leak points. If the dye is pulled toward a crack or gap, the leak location is confirmed. This works well for skimmers, fittings, and return jets.
Structural Inspection
The technician will also visually inspect the pool shell, tile line, coping, and deck. Furthermore, they will check fittings, lights, and the main drain cover for signs of wear or damage. A thorough inspection gives you a complete picture of your pool’s condition.
Why Ignoring a Pool Leak Is Costly
Some homeowners put off leak detection because they do not want the hassle. However, the cost of waiting is almost always higher than the cost of acting early.
- Wasted water: Even a small leak wastes a significant amount of water over time.
- Higher chemical costs: You spend more on chemicals trying to balance diluted pool water.
- Deck and foundation damage: Escaping water can erode soil and crack concrete around your pool.
- Equipment stress: Your pump and filter work harder when water levels drop unexpectedly.
- Bigger repairs later: Small leaks grow into larger structural problems when left untreated.
Therefore, early detection is always the smarter financial choice. Additionally, it protects the long-term value of your pool and your property.
Gilbert Pool Leak Detection: Frequently Asked Questions
How do I know if my pool is leaking or just evaporating?
Run the bucket test described earlier in this post. If your pool loses more water than the bucket over 24 hours, you likely have a leak. However, a professional inspection is the most reliable way to confirm it.
How long does a leak detection appointment take?
Most professional leak detection visits take anywhere from one to three hours, depending on pool size and complexity. Additionally, the technician will walk you through their findings and explain your repair options before leaving.
Can a pool leak fix itself?
In very rare cases, a tiny crack in plaster may self-seal temporarily. However, this is not something you should count on. Most leaks grow over time and require professional repair.
Do I need to drain my pool for leak detection?
Not always. Many leaks can be found and confirmed without draining the pool entirely. Your technician will determine the best approach based on where the leak is suspected.
