A leaking pool is one of the most stressful problems a homeowner can face. You notice the water level dropping, and you wonder whether it’s evaporation or something more serious. Proper leak detection is the key to protecting your pool, your yard, and your wallet.
In Gilbert, AZ, pools work hard all year long. The intense desert heat, constant sun exposure, and heavy use can all stress your pool’s structure and equipment. Therefore, catching a leak early can save you from much larger repair bills down the road.
This guide walks you through everything you need to know about finding and fixing pool leaks. Whether you own a home in Gilbert, Chandler, Mesa, or Queen Creek, these tips will help you act quickly and confidently.
How to Tell If Your Pool Is Actually Leaking
First, it’s important to understand that not every water loss is a leak. Pools naturally lose water through evaporation, splash-out, and backwashing. However, if your pool is losing water faster than normal, you may have a real problem.
In Gilbert’s hot summers, evaporation can account for a noticeable drop in water level each week. On the other hand, a structural or equipment leak will cause water loss that goes well beyond normal evaporation rates.
The Bucket Test: A Simple First Step
The bucket test is the easiest way to check for a pool leak at home. Fill a bucket with pool water and set it on a pool step so it sits partially submerged. Mark the water level inside the bucket and on the pool wall. Then, wait 24 to 48 hours and compare the two levels.
If the pool loses significantly more water than the bucket, you likely have a leak. Because this test is simple and free, it’s always the best place to start your investigation.
Other Warning Signs of a Pool Leak
Beyond water loss, several other signs point to a leak. Watch for these common indicators:
- Wet or soggy spots in your yard near the pool equipment pad
- Cracks in the pool shell, tile, or coping
- Air bubbles coming from the return jets
- Needing to add water more than once a week
- Unexplained increases in your water bill
- Loose or lifting pool tiles around the waterline
Additionally, if your pool chemicals seem to disappear faster than usual, water loss may be diluting them as you top off the pool repeatedly. This is a subtle but real sign that something is off.
Common Places Pool Leaks Occur
Pool leaks can originate from many different locations. Knowing the most common spots helps you narrow down the problem before calling a professional. Furthermore, understanding where leaks happen helps you explain the issue clearly when you do reach out for help.
The Pool Shell and Plaster
Cracks in the pool shell are one of the most common sources of leaks. Over time, ground movement, temperature changes, and aging plaster can create small fissures in the pool surface. In the East Valley, the clay-heavy soil can shift seasonally, putting extra stress on pool structures.
Even hairline cracks can allow significant water to escape over time. Therefore, you should inspect your pool shell regularly, especially after monsoon season or periods of heavy rain.
Skimmers and Return Lines
The skimmer is the rectangular opening on the pool wall that pulls surface water into the filtration system. Skimmer bodies are prone to cracking, especially as pool plaster ages and the bond between the skimmer and shell weakens. Meanwhile, return lines — the pipes that push filtered water back into the pool — can develop cracks underground.
Leaks in underground plumbing are harder to detect visually. As a result, a professional pressure test is often needed to confirm whether your pipes are the source of the problem.
Pool Equipment and Fittings
Your pump, filter, heater, and valves all have seals, gaskets, and fittings that can wear out. A slow drip from a pump lid O-ring or a loose union fitting can add up to significant water loss over days and weeks. Moreover, equipment leaks often go unnoticed because they happen at the equipment pad, away from the pool itself.
Inspecting your equipment pad regularly is a smart habit. Look for moisture, mineral staining, or dripping water around any fittings or connections.
DIY Leak Detection Tips for Gilbert Homeowners
While some leaks require professional tools to locate, there are several steps you can take on your own. These tips work well for homeowners in Gilbert, Chandler, Gilbert Ranch, and Power Ranch who want to gather information before scheduling a service call.
Check the Equipment Pad First
Start by walking around your equipment pad and looking for any obvious signs of moisture. Feel the ground around the base of your pump and filter. Also, check the valves and unions for drips or mineral deposits, which indicate long-term water exposure.
Next, run your pump and watch for air bubbles coming from the return jets inside the pool. Air in the return lines usually means there is a suction-side leak somewhere between the skimmer and the pump.
Use Dye Testing Around Suspect Areas
Dye testing is a simple technique you can try yourself. Turn off your pump to allow the water to become still. Then, using a pool dye syringe or a few drops of dark food coloring, carefully release dye near a suspected crack or fitting. If the dye gets pulled toward a gap or crack, water is escaping through that point.
This method works particularly well around skimmer throats, return fittings, and lights. However, it requires calm water and patience to be effective.
Monitor Water Loss With and Without the Pump Running
Another useful test is to track water loss with the pump running and then again with the pump off. Mark your water level and run the pump normally for 24 hours. Then, mark the level again and turn the pump off for another 24 hours.
If the pool loses more water when the pump is running, the leak is likely on the pressure side of the plumbing. If it loses more water with the pump off, the leak is more likely structural. This simple comparison helps narrow down where to look next.
When to Call a Professional for Pool Leak Detection
Some leaks are straightforward to find and fix. Others are hidden underground or inside walls where no homeowner can reasonably reach them. In those cases, professional leak detection is not just helpful — it’s necessary.
Professional pool technicians use specialized tools to locate hidden leaks without tearing up your yard. Pressure testing, electronic listening devices, and underwater cameras are all common tools used by experienced technicians. As a result, they can pinpoint the exact location of a leak quickly and efficiently.
If you’ve completed the bucket test and basic visual inspection but still can’t find the source of water loss, it’s time to bring in an expert. Contact Valley Pool to schedule a professional leak inspection and get a clear answer fast.
What to Expect During a Professional Leak Inspection
When a Valley Pool technician visits your home, they will start with a full visual inspection of your pool and equipment. Then, they will perform a series of pressure tests on your plumbing lines to check for leaks underground. They will also inspect the shell, fittings, and lights carefully.
After the inspection, your technician will explain exactly what they found and walk you through your repair options. We believe in clear, honest communication so you can make the best decision for your pool and your budget.
How Pool Leaks Are Repaired
The repair method depends entirely on where the leak is located and how severe it is. Surface cracks in the pool plaster are often repaired with hydraulic cement or epoxy underwater patching compounds. These repairs can frequently be made without draining the pool.
Skimmer cracks are typically sealed with two-part epoxy or polyurethane sealants designed for underwater use. Moreover, if the skimmer body is severely damaged, it may need to be replaced entirely.
Underground pipe leaks often require locating the damaged section and either spot-repairing it or re-routing the affected line. Fortunately, modern detection methods mean technicians rarely have to excavate large areas to find the problem.
Equipment leaks are usually the simplest to fix. Replacing worn O-rings, tightening unions, or installing a new pump lid can often resolve the issue within a single service visit.
Preventing Pool Leaks in Gilbert’s Desert Climate
Prevention is always better than repair. In Arizona’s desert environment, pools face unique challenges that increase the risk of leaks over time. Fortunately, regular maintenance and periodic inspections can significantly reduce your risk.
Here are some practical prevention tips for East Valley pool owners:
- Schedule annual equipment inspections to catch worn seals and fittings before they fail
- Maintain proper water chemistry to prevent corrosive water from damaging your shell and fittings
- Inspect pool coping and tile after monsoon season for cracks or shifting
- Avoid letting the pool water level drop too low, which can stress skimmers and seals
- Have your pool replastered on schedule to prevent surface cracks from forming
Additionally, if you notice any soft or wet spots in your yard near the pool or equipment pad, investigate them promptly. Early action almost always leads to simpler and less expensive repairs.
Frequently Asked Questions About Pool Leak Detection
How much water loss is normal for a pool in Gilbert, AZ?
In Gilbert’s desert heat, a pool can naturally lose water each week through evaporation, especially in summer. If you’re losing significantly more than that, it’s worth investigating further. The bucket test is a quick and easy way to check whether your loss exceeds normal evaporation rates.
Can I swim in my pool if it has a leak?
In most cases, yes, you can still swim while waiting for a repair. However, you should continue topping off the water to maintain proper levels and avoid exposing the skimmer or pump to air. Some structural leaks may pose safety concerns, so it’s best to consult a professional if you’re unsure.
How long does a professional pool leak inspection take?
A thorough pool leak inspection typically takes one to two hours, depending on the size of your pool and the complexity of your plumbing. Pressure testing underground lines may add additional time. Your technician will give you a clear timeline when they arrive.
Will a pool leak get worse if I ignore it?
Yes, almost always. Even a small leak can erode soil beneath the pool shell, damage nearby landscaping, and lead to structural issues over time. Furthermore, ongoing water loss drives up your water bill and forces your equipment to work harder. Addressing a leak early is always the smarter and less expensive choice.
Do pool leaks always show visible cracks?
Not always. Many leaks originate in underground plumbing or behind fittings where they are invisible to the naked eye. That is exactly why professional detection tools are so valuable. If you suspect a leak but can’t find a visible crack, a professional inspection is the right next step.
