How To Find Pool Leaks In Underground Plumbing

How To Find Pool Leaks In Underground Plumbing

Leak Detection For Hidden Underground Pool Leaks


For weeks now, you've been adding water to your Phoenix pool almost daily, struggling to keep your chemicals balanced no matter what you try. Your latest water bill arrived with a number that made your heart sink, nearly double your usual amount. The growing certainty that there's a leak somewhere in your underground plumbing fills you with dread about potentially digging up your beautiful pool deck or landscaping. You know something needs to be done, but the uncertainty of what lies beneath is overwhelming.


This is exactly the situation where Arizona Leak Pros steps in with our specialized locating equipment and years of experience solving Arizona's unique underground pool leak challenges. Finding leaks in underground pool plumbing requires professional-grade tools, extensive training, and intimate knowledge of how Phoenix soil conditions affect pool systems. Our systematic approach ensures we locate your leak precisely without unnecessary excavation or guesswork.

Recognizing the Warning Signs Of An Underground Pool Leak


Before diving into our detection process, it's important to understand the warning signs that indicate you might have an underground plumbing leak. Arizona Leak Pros has seen these patterns countless times, and recognizing them early can save you significant money and prevent extensive damage.

Unexplained Water Loss


In Arizona's hot climate, it's normal to lose about ¼ inch of water per day to evaporation, especially during the summer months. However, if you're consistently losing more water than this, or if you find yourself adding water to your pool more frequently than usual, it's time to investigate further. Underground plumbing leaks can cause water loss that far exceeds normal evaporation rates.


Equipment Area Issues


Puddles that repeatedly appear near your pump, filter, or heater can indicate underground plumbing problems. While surface equipment leaks are often visible, they can also signal issues with underground connections that feed into your visible plumbing.


Landscape and Soil Changes


Keep an eye out for patches of grass or plants that are unusually green or growing faster than surrounding vegetation. In desert landscaping, you might notice areas that stay damp longer than they should or where the soil appears softer or more settled.

Underground water doesn't always surface directly above the leak. We often find underground leaks by following water as it travels downhill from the actual leak location. Wet spots that appear consistently in areas away from your pool can indicate water traveling underground from a leak in your plumbing system.


Structural Warning Signs


Underground water can cause significant structural changes over time. Cracks in your pool deck, settling or shifting of hardscape materials, and unexplained changes in the level of concrete surfaces can all indicate water undermining the foundation. 


Air in Your Pool System


If your pool pump basket frequently fills with air, or if you notice air bubbles coming from your return jets, this can indicate a suction-side leak in your underground plumbing. These air intrusion issues often develop gradually and can be easy to dismiss as minor problems, but they frequently signal more serious underground leaks.


Unusual Water Bills



A sudden spike in your water bill without corresponding changes in your usage patterns is often the first sign homeowners notice. Underground plumbing leaks can waste hundreds or even thousands of gallons of water monthly, creating dramatic increases in utility costs that get worse over time.

Why Underground Plumbing Leaks Are So Challenging

Underground pool plumbing leaks represent one of the most complex detection challenges in the pool industry. Unlike visible surface leaks, these problems hide beneath concrete decks, landscaping, and several feet of soil. The water escapes silently, often traveling considerable distances before surfacing, making it nearly impossible to pinpoint the source without professional equipment.

Arizona's desert climate adds another layer of complexity. Our intense heat causes dramatic soil expansion and contraction, putting constant stress on underground pipes and fittings. Clay-heavy soils common in the Phoenix area can shift significantly with moisture changes, creating stress points where leaks commonly develop. These conditions require specialized knowledge that only experienced pool leak detectors in Phoenix possess.


The stakes are high when dealing with underground plumbing leaks. Water escaping from pipes can undermine pool structures, damage foundations, and create expensive landscape problems. Every day a leak goes undetected means more water loss, higher utility bills, and potential structural damage that grows more costly to repair.

Our Specialized Leak Locating Methods


Our team utilizes state-of-the-art equipment specifically designed for underground leak detection. This technology allows us to locate leaks with absolute precision, minimizing excavation and reducing repair costs for our clients.


Computerized Leak Analysis


We often start our underground plumbing investigation with our computerized Leakalyzer. This sophisticated device measures exactly how much water your pool loses over specific time periods, helping us confirm the presence of a leak and estimate its severity. By testing with your pool equipment both on and off, we can determine whether the leak is in your suction lines, return lines, or pool structure itself.


Pressure Testing Plumbing Lines


Our pressure testing equipment is the gold standard for isolating leaks in underground plumbing. We systematically isolate each section of your pool's plumbing system, pressurizing individual lines while monitoring for pressure drops. This process identifies the exact line with the leak, allowing us to focus our detection efforts on a specific area.


Acoustic Detection Equipment


Once we've identified the problematic line through pressure testing, our acoustic detection equipment takes over. We use advanced electronic listening devices that can detect the sound of water escaping from pressurized pipes underground. These sensitive instruments amplify the characteristic sounds that leaks make, allowing our technicians to pinpoint exact locations even when pipes are buried several feet deep.



Water escaping from PVC pipes under pressure creates distinct acoustic signatures that our equipment can isolate from background noise. Our technicians are trained to interpret these sounds and track them to their source with remarkable accuracy.

The Cost of Precision

While professional leak detection requires an investment, the precision of our services typically saves clients significant money compared to alternative approaches. Guessing at leak locations or attempting DIY detection often leads to unnecessary excavation, property damage, and missed leaks that continue causing problems.


Our systematic approach means we find leaks quickly and accurately, reducing the time and cost associated with repairs. The water savings alone often justify the detection cost within a few months, especially given Arizona's water rates and the potential for significant daily water loss from underground plumbing leaks.
