Your pool loses a little water every day. Heat, splashing, and evaporation are all completely normal. However, when your water level keeps dropping faster than expected, you may be dealing with something more serious. Leak detection is the process of finding exactly where your pool is losing water — and scheduling it at the right time can save you a significant amount of money.
Mesa homeowners face unique challenges with their pools. The intense Arizona sun, shifting soil, and hard water all put stress on pool equipment and structure. Because of this, leaks can develop faster here than in cooler climates. Catching them early is the smart move.
In this guide, we walk you through the key signs that your pool has a leak, when to call a professional, and why acting quickly matters for Mesa and East Valley pool owners.
How to Tell If Your Pool Is Actually Leaking
Not every drop in water level points to a leak. First, you need to rule out normal evaporation. Arizona summers are brutal, and evaporation rates here are much higher than in other states.
A simple bucket test can help. 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. Wait 24 hours, then compare the two levels. If the pool loses significantly more water than the bucket, you likely have a leak worth investigating.
Warning Signs That Point to a Leak
There are several clear signals that your pool needs professional leak detection. Watch for these warning signs:
- You add water more than twice a week just to keep the level normal.
- Your water bill has increased without a clear explanation.
- Wet spots or soft ground appear near the pool equipment or along the pool shell.
- Cracks are visible in the pool deck, tile line, or plaster surface.
- Your pump loses prime repeatedly or runs dry.
- Chemical usage suddenly increases even though your routine has not changed.
Any one of these signs warrants a closer look. Furthermore, multiple signs appearing together make professional leak detection an urgent priority.
The Best Times to Schedule Pool Leak Detection in Mesa AZ
Timing matters when it comes to leak detection. Certain seasons and situations make it especially important to act quickly. Here is what Mesa and East Valley pool owners should keep in mind.
Before Summer Swimming Season
Spring is one of the best times to schedule a leak inspection. You want your pool fully ready before temperatures climb into triple digits. Additionally, catching a leak in spring gives you time to complete repairs without rushing.
Many Gilbert and Mesa homeowners schedule a pre-season checkup in March or April. This helps avoid delays during the peak summer months when pool service companies are at their busiest.
After a Hard Arizona Winter
Arizona winters are mild compared to other states. However, overnight temperature swings and occasional freezes can still stress pool plumbing and equipment. As a result, small cracks or loose fittings may develop during the cooler months.
If your pool sat unused for most of the winter, inspect it carefully before reopening. Look for new cracks in the plaster, movement along the tile line, or unusual moisture near the equipment pad.
After Heavy Monsoon Rains
Mesa and the broader East Valley experience monsoon season each summer. Heavy rain and soil saturation can shift the ground beneath your pool. This movement can stress the pool shell and underground plumbing.
After a significant monsoon storm, watch your water level closely over the next few days. Meanwhile, check for new deck cracks or shifting around the pool coping. These are signs that a structural or plumbing leak may have developed.
When You Notice Any Sudden Change
Do not wait for the “perfect” time if something seems off right now. A sudden change in water level, unexplained chemical imbalances, or new wet patches near the pool equipment are all reasons to call a professional immediately. The longer a leak goes unaddressed, the more damage it can cause.
Why Pool Leaks Are Especially Risky in the East Valley
Leaks are a concern for pool owners everywhere. However, the East Valley’s specific soil and climate conditions make leaks particularly damaging if left unchecked.
Much of Mesa, Chandler, Gilbert, and Queen Creek sits on expansive clay and caliche soil. This type of soil contracts when dry and expands when wet. Because of this, a leaking pool constantly wets and dries the surrounding ground. Over time, this cycle causes the soil to shift unevenly beneath the pool shell and deck.
Additionally, the hard water common throughout Maricopa County accelerates wear on pool fittings, gaskets, and seals. Over time, this leads to slow leaks at equipment connections that are easy to miss.
In short, East Valley conditions create a higher risk of leak-related structural damage than in many other regions. Acting quickly protects your investment.
Where Pool Leaks Most Commonly Occur
Understanding where leaks happen helps you know what to look for. Pool professionals typically check several key areas during a leak detection visit.
Pool Shell and Plaster
Cracks in the plaster or gunite shell are a common leak source. They can range from hairline surface cracks to deeper structural fractures. Therefore, any visible cracking should be documented and evaluated by a professional.
Plumbing Lines
Underground plumbing carries water between the pool and the equipment pad. Pipe joints, fittings, and return lines can all develop leaks. These are often invisible from the surface, which is why pressure testing is an important part of the detection process.
Equipment and Fittings
Pumps, filters, heaters, and valves all have seals and gaskets that wear over time. A slow drip at the equipment pad may seem minor. On the other hand, small equipment leaks can cause significant water loss over weeks and months.
Skimmers and Returns
The skimmer throat and return fittings are common leak points. Over time, the sealant around these fittings can crack or separate from the pool shell. This is especially common in older pools throughout Mesa and Tempe.
What Happens During a Professional Leak Detection Visit
If you suspect a leak, a professional technician will use a combination of methods to locate the problem. The process is thorough and systematic.
First, the technician will perform a visual inspection of the pool shell, deck, tile line, and equipment. Next, they will conduct a pressure test on the plumbing lines to check for pressure drops that indicate a breach. They may also use dye testing near fittings and suspicious areas. Finally, they will give you a clear report of what they found and the options available for repair.

Tips to Reduce Your Risk of Pool Leaks
While leaks can happen to any pool, there are steps you can take to reduce the risk. These habits apply to pool owners throughout the East Valley.
- Keep your water chemistry balanced. Imbalanced water accelerates deterioration of plaster, grout, and fittings.
- Inspect the equipment pad regularly. Look for drips, moisture stains, or rust near connections.
- Watch for deck movement. Cracks or gaps along the coping can signal shifting soil beneath the pool.
- Schedule annual professional inspections. A trained technician catches early-stage issues before they become costly repairs.
- Repair minor cracks promptly. Small surface cracks can deepen and spread if ignored.
Furthermore, working with a reliable local pool service team means you have a professional relationship already in place when an issue arises. Talk with a pool care expert at Valley Pool about setting up a maintenance plan that keeps your pool in great shape year-round.
Frequently Asked Questions About Pool Leak Detection
How much water loss is normal for a Mesa AZ pool?
Most pools lose water through evaporation, especially during Arizona summers. Typically, losing up to a quarter inch per day is considered within a normal evaporation range. However, if you are consistently losing more than that, leak detection is worth scheduling.
Can I find a pool leak myself?
You can use the bucket test to confirm whether evaporation or a leak is the cause. Additionally, you can visually check the equipment pad and pool shell for obvious issues. However, locating the exact source of a leak usually requires professional tools and testing methods.
How long does pool leak detection take?
A professional leak detection visit typically takes a few hours, depending on the size and complexity of your pool system. In some cases, a straightforward leak is found quickly. In others, more detailed pressure testing and dye work may be needed.
Will a leak get worse if I ignore it?
Yes. Leaks almost always worsen over time. Moreover, the surrounding soil erosion and equipment strain caused by ongoing water loss can create secondary problems that are more expensive to repair.
Does Valley Pool Service handle leak detection in Mesa and nearby cities?
Yes. Valley Pool Service serves Mesa, Gilbert, Chandler, Queen Creek, and surrounding East Valley communities. Our technicians are familiar with local pool construction styles, soil conditions, and equipment common throughout the region.
