A small pool leak can quietly drain hundreds of gallons of water each week. Most Gilbert homeowners never notice until their water bill spikes or their pool equipment starts struggling. That is when leak detection becomes one of the smartest investments you can make as a pool owner.
Arizona’s intense heat puts constant stress on pool shells, fittings, and plumbing lines. Because of this, leaks develop faster here than in cooler climates. The good news is that catching a leak early almost always costs far less than repairing the damage it leaves behind.
At Valley Pool Service, our Gilbert pool technicians know how to find leaks quickly and accurately. In this post, we will walk you through why leaks happen, how professionals find them, and exactly how early detection saves you real money.
Why Pool Leaks Are So Common in Gilbert, Arizona
Gilbert and the surrounding East Valley experience some of the harshest pool conditions in the country. Summer temperatures routinely climb well above 110 degrees. That extreme heat causes pool materials to expand and contract repeatedly throughout the year.
Over time, this cycle weakens fittings, seals, and plumbing joints. Additionally, shifting soil beneath your pool deck can put stress on underground pipes. These conditions make leaks far more likely for Arizona pool owners than for homeowners in milder states.
Common Causes of Residential Pool Leaks
Understanding what causes leaks helps you catch warning signs early. Here are the most common culprits our technicians find in Gilbert-area pools:
- Cracked pool shell or plaster: Heat and ground movement can create hairline cracks that grow over time.
- Failing fittings and returns: The fittings where water enters and exits the pool can loosen or degrade.
- Worn pump and filter seals: Equipment seals dry out quickly in the Arizona heat.
- Underground plumbing cracks: Pipes buried beneath your deck can crack without any visible sign above ground.
- Loose or damaged skimmer: Skimmer baskets and throats are frequent leak points, especially in older pools.
Furthermore, pools in newer communities like Cooley Station or Morrison Ranch can still develop leaks if equipment was improperly installed during construction. Age is not always the deciding factor.
How to Tell If Your Pool Is Leaking
Every pool loses some water to evaporation. However, evaporation alone does not explain dramatic water loss. Knowing the difference can save you from ignoring a serious problem.
One simple test is the bucket method. 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. After 24 hours, compare the two levels. If your pool lost significantly more water than the bucket, you likely have a leak.
Warning Signs You Should Not Ignore
Beyond water loss, there are other signs that point to a possible leak. Watch for these red flags around your pool:
- Wet or soggy ground around your equipment pad or pool deck
- Cracks appearing along the pool shell or tile line
- Your pump running louder than usual or losing prime
- Constantly adding chemicals to maintain balance
- Higher-than-normal water or electric bills
- Algae growth that returns quickly despite treatment
If you notice any of these signs, do not wait. Therefore, the sooner you schedule a professional leak detection inspection, the less damage you are likely to face. Talk with a pool care expert at Valley Pool Service to get an honest assessment right away.
What Professional Leak Detection Actually Involves
Many homeowners assume finding a leak is straightforward. In reality, locating the exact source of a pool leak requires specific tools and hands-on experience. Professional technicians use a combination of pressure testing, dye testing, and equipment inspection to pinpoint the problem.
Pressure testing involves isolating sections of your pool’s plumbing and pressurizing them to detect drops that indicate a crack or breach. This method is especially useful for underground lines that you cannot see or access without digging.
Dye Testing and Equipment Inspection
Dye testing is another reliable technique our technicians use. A small amount of colored dye is released near suspected leak points. If the dye gets pulled toward a crack or gap, that confirms the leak location. It is a precise and non-invasive way to find surface leaks around fittings and returns.
In addition, our team inspects your pump, filter, heater, and valves for signs of seal failure or loose connections. Equipment leaks are sometimes overlooked, but they can waste just as much water as a crack in the pool shell. Moreover, catching an equipment issue early often prevents a full replacement down the road.
Why DIY Leak Detection Falls Short
It can be tempting to try finding a leak yourself. However, without pressure testing equipment and trained eyes, most homeowners only find the most obvious leaks. Underground plumbing issues and subtle fitting failures are nearly impossible to locate without professional tools.
Guessing at a leak location and digging in the wrong spot wastes time and money. On the other hand, a professional inspection gives you an accurate diagnosis the first time. This means faster repairs and fewer disruptions to your pool schedule.
How Leak Detection Saves You Money
This is where the real value becomes clear. A professional leak detection service pays for itself in multiple ways. First, catching a small leak early prevents it from growing into a major structural repair.
Second, fixing a leak stops the constant water loss that drives up your utility bills month after month. In the East Valley, where water is a precious and costly resource, this matters significantly. Homeowners in Mesa, Chandler, and Queen Creek face similar water costs and benefit from the same proactive approach.
Protecting Your Pool Equipment Investment
Leaks do not just waste water. They also harm your equipment. When water levels drop too low, your pump can run dry and overheat. As a result, a pump that might have lasted many more years can fail prematurely.
Additionally, undetected leaks allow water to saturate the soil beneath your pool deck. Over time, this erodes the support structure and can cause deck cracking or even pool shell shifting. Repairing structural damage like this is far more expensive than a routine leak inspection and early fix.
Saving on Chemicals and Water
When your pool leaks, you constantly refill it with fresh water. Fresh water dilutes your carefully balanced chemicals. Because of this, you end up adding more chlorine, pH adjusters, and stabilizers far more often than you should.
Furthermore, the excess water added to compensate for leaks can throw off your calcium hardness and total dissolved solids levels. This creates a cycle of chemistry imbalance that is both frustrating and expensive. Stopping the leak stops the cycle.

Leak Detection for Different Types of Gilbert Area Pools
Gilbert and the surrounding communities have a wide variety of pool types. Older plaster pools in established neighborhoods can develop surface cracks over time. Newer pebble-finish pools may have fitting issues from installation. Fiberglass pools can separate from their fittings as the shell flexes.
Our technicians are familiar with the pool types and construction methods common throughout the East Valley. Whether you live in a master-planned community in Gilbert or an older neighborhood in nearby Tempe or Ahwatukee, our team can tailor the leak detection process to your specific pool.
Seasonal Considerations for Arizona Pool Leaks
Arizona pool owners use their pools year-round. However, the transition from extreme summer heat to cooler winter nights creates unique stress on pool materials. Additionally, monsoon season can shift soil and increase pressure on underground plumbing.
For this reason, scheduling a professional inspection at least once a year is a smart habit. Catching seasonal damage early keeps your pool swim-ready and prevents small issues from turning into expensive surprises.
Frequently Asked Questions About Pool Leak Detection
How do I know if my pool is losing water to evaporation or a leak?
The bucket test is a reliable starting point. If your pool loses noticeably more water than the bucket over 24 hours, a leak is likely. A professional inspection will confirm the source.
How long does a professional leak detection service take?
Most inspections take a few hours depending on the pool size and complexity. Underground plumbing inspections may take longer. Your technician will give you a realistic time estimate before starting.
Can a pool leak damage my yard or home foundation?
Yes. Persistent leaks can saturate the soil around your pool and yard. Over time, this can undermine your deck, landscaping, and in severe cases, structures near the pool. Early detection prevents this kind of collateral damage.
Is pool leak detection covered by homeowners insurance?
Coverage varies by policy and the cause of the leak. We recommend contacting your insurance provider directly. Our team can provide documentation of the leak source to support your claim if needed.
How often should I schedule a leak inspection in Gilbert, AZ?
At minimum, once a year is a good practice for Arizona pool owners. Additionally, schedule an inspection any time you notice unexplained water loss, wet spots near your equipment, or rising utility bills.
