A leaking pool is one of the most stressful problems a homeowner can face. However, many Mesa, AZ residents make avoidable mistakes when trying to handle leak detection on their own. These errors can turn a small issue into an expensive repair. Therefore, knowing what not to do is just as important as knowing what to do.
Pool leaks are especially common in Arizona because of the extreme heat, shifting soil, and heavy equipment use throughout the year. As a result, even well-maintained pools in Mesa, Gilbert, Chandler, and Queen Creek can develop leaks without obvious warning signs. The sooner you catch a leak, the better your chances of limiting damage.
In this guide, the Valley Pool Service team walks you through the most common leak detection mistakes pool owners make. Additionally, we share practical tips to help you protect your pool and your wallet.
Why Pool Leak Detection Matters in Mesa AZ
Mesa summers push pools hard. Pumps run longer, water evaporates faster, and equipment works overtime. Because of this, it can be difficult to tell the difference between normal evaporation and an actual leak. Many homeowners assume water loss is always evaporation, and that assumption costs them money.
A leak left untreated can erode the soil beneath your pool shell. Furthermore, it can damage your pump, filter, and plumbing. In the Mesa area, where clay-heavy soil is common, underground leaks can shift your pool structure over time. So early detection is critical.
What Counts as Too Much Water Loss?
Arizona pools do lose water to evaporation, especially in summer. However, losing more than a quarter inch of water per day likely signals a leak. First, place a bucket of water on your pool step and mark both water levels. Then check both levels after 24 hours. If your pool loses noticeably more water than the bucket, you may have a leak.
This simple test is called the bucket test. It gives you a baseline before calling a professional. Moreover, it costs nothing and takes just a few minutes to set up.
Mistake #1: Assuming Evaporation Is Always the Cause
This is the most common mistake Mesa pool owners make. Evaporation is real, but it has limits. On the other hand, a pool that drops several inches in a week is almost certainly leaking somewhere.
Many homeowners wait weeks or months before investigating further. Meanwhile, water seeps into the surrounding soil, eroding the pool deck or shifting the equipment pad. By the time they call a professional, the damage is much more extensive.
Always run the bucket test first. Additionally, check your water bill for unusual spikes, since that can confirm you are losing water beyond normal use.
Mistake #2: Only Checking the Pool Shell
When most homeowners think about pool leaks, they immediately look at the pool shell for cracks. However, plumbing leaks are actually quite common. Pipes that run underground from your pump to your pool can crack, corrode, or pull apart at the joints.
In addition, leaks often occur at equipment connections. Your pump lid, filter housing, and valve fittings are all common culprits. Therefore, limiting your inspection to the visible pool surface means you could easily miss the real problem.
Where Leaks Commonly Hide in Arizona Pools
- Skimmer throat and faceplate: Cracks here are very common, especially in older pools.
- Return line fittings: These can loosen over time due to pressure changes.
- Main drain plumbing: Harder to inspect, but a frequent source of underground leaks.
- Pump and filter connections: Vibration from equipment eventually weakens seals and fittings.
- Pool light conduit: Water can travel through the conduit if the seal is compromised.
A full professional inspection covers all of these areas. Moreover, trained technicians use pressure testing and dye testing to pinpoint leaks that are impossible to find by eye.
Mistake #3: Using DIY Leak Sealants Without a Diagnosis
Pool supply stores sell various sealant products that claim to fix leaks. However, pouring a sealant into your pool without knowing the exact leak location is rarely effective. Furthermore, some sealants can clog your filter system or interfere with water chemistry.
These products are not a replacement for proper leak detection. In fact, they sometimes make the underlying problem harder to find later. As a result, a professional ends up spending more time diagnosing the issue, which can increase your repair costs.
If you suspect a leak, the smarter first step is to request a professional inspection. The Valley Pool team serves Mesa, Gilbert, Tempe, and surrounding East Valley communities with thorough equipment and plumbing evaluations.
Why Guesswork Makes Leaks Worse
Every pool system is different. Therefore, what works for a neighbor’s pool may not apply to yours. Pool technicians use pressure testing to isolate specific plumbing lines. They also use dye testing, which involves releasing a small amount of colored dye near suspected leak points to watch for movement.
These methods are precise and non-invasive. Additionally, they prevent unnecessary digging or surface damage. Guessing and patching without a diagnosis usually delays the real fix and wastes money in the process.
Mistake #4: Ignoring Wet Spots Around the Equipment Pad
If you notice soggy ground, rust stains, or standing water near your pump and filter area, do not ignore it. Many homeowners assume a sprinkler is the cause. However, wet soil around your equipment pad often points directly to a plumbing or equipment leak.
In Gilbert and Mesa, where temperatures regularly exceed 110 degrees in summer, standing water near equipment evaporates quickly. Because of this, you might only notice the problem on cooler mornings or after running your system overnight. Check the area right after your pump cycles off for the clearest signs.
Talk with a pool care expert at Valley Pool if you notice anything unusual around your equipment. Early action prevents much larger repair bills down the road.
Mistake #5: Delaying Professional Help Too Long
Many pool owners spend weeks troubleshooting a suspected leak on their own. Furthermore, some worry about the cost of a professional inspection and put it off. However, delaying a professional evaluation almost always makes the problem more expensive to fix.
Water loss adds up quickly. In addition, the soil erosion and structural stress caused by an undetected leak can lead to far more costly repairs, including resurfacing, deck replacement, or major plumbing work. Therefore, acting sooner saves money in the long run.
Signs You Should Call a Pool Professional Right Away
- Your pool loses water even when the pump is turned off.
- You notice cracks forming along the waterline tile or pool deck.
- Your water bill has increased without a clear reason.
- You must add water to your pool more than twice per week.
- Wet or sunken areas appear in your lawn near pool plumbing lines.
If you are seeing any of these signs, do not wait. Contact Valley Pool to schedule a service visit and get a professional assessment of your pool as soon as possible.

Frequently Asked Questions About Pool Leak Detection
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 significantly more water than the bucket over 24 hours, you likely have a leak. A professional can confirm with pressure testing.
Can a pool leak fix itself?
In very rare cases, minor leaks at fittings may slow temporarily. However, leaks do not repair themselves. Furthermore, most leaks worsen over time. Always get a professional evaluation to determine the best repair option.
How long does a pool leak inspection take?
A thorough inspection typically takes one to two hours, depending on your pool size and plumbing complexity. More involved pressure testing may take longer. Your technician will give you a realistic time estimate before starting.
Is it safe to keep swimming while my pool is leaking?
It depends on the leak location and severity. However, significant water loss can affect water chemistry and equipment performance. Therefore, it is best to have a professional assess the situation before continuing regular pool use.
