Global Pools Specializes in Pool, Spa, and Fountain leak detection and repairs, Servicing both Residential and Commercial Customers - No job is too big or too small. Utilizing state of the art electronic equipment manufactured in house by LEAKTRONICS, as well as specialized visual testing and pressure testing the various pipes to and from the filtration equipment, Global pools can find any leak in the pool.


Changing the way swimming pool leaks are located, LEAKTRONICS LEAK DETECTION EQUIPMENT makes it no longer necessary to get into a pool to locate a leak. Pressure testing is no longer the only option. It all starts with fact gathering. Then we arrive to perform the pool leak detection. The next step is to pre-locate the leak with LEAKTRONICS POOL SCOPE. By holding the POOL SCOPE in front of an open line, we’re able to pre-locate a leak in a line. When we know which line is leaking, it’s time to get out the PIPE MIC. (Sorry, not time to pressure test yet). The PIPE MIC is small enough to fit inside lines to get you closer to the leak from inside the pipe. The noise is louder at the point of the leak.

If we aren’t able tp pinpoint the Leak with the PIPE MIC, now it’s time to pressure test. LEAKTRONICS PRESSURE RIG contains a mixing chamber to mix air and water to create a boiling noise at the point of the leak. When the line is under pressure and we use the LEAKTRONICS hard contact DECK PLATE or SOIL PROBE to locate the leak under the patio slab or grassy area, the closer we are to the leak, the louder the noise will become. When we reach the loudest area, “X”marks the spot where the leak is!

Is my pool leaking?


● If you Notice a larger than normal (more than ¼ inch per day) decrease in pool water level, you have a good reason to suspect a pool leak.
● If your pool has an automatic fill device, it might be harder to detect a water leak.
● Increase in chemical demands (to treat new water that is added to the pool) because of a leak
● Increased water bills
● Cracks on the pool deck resulting from settling earth

● Structural Crack(s) in the pool
● Unexplainable evidence of water loss
● The pool tiles are either loose or have fallen off
● The ground around your pool always seems to be soggy or contains standing water and grass that is uneven.
(In most cases, this means that your auto-fill is releasing water non-stop).
● There are bubbles in your pump. This often means that your main drain has a leak.


Check your Pool for Leaks at least once a month if you live in Florida due to evaporation causing water loss. It is key to remember that evaporation should be no more than ¼ of an inch in a 24 hour period; anything more than 1/8 of an inch in the same 24 hour period is evidence of an issue.

Doing a BUCKET TEST can confirm an issue if one exists. Here are the steps:

  1. Fill your pool to the normal operating level. Take a hose and fill the pool to where it would normally be prior to use.
  2. Fill a 5 Gallon Bucket with pool, spa or fountain water about 3-4 inches from the top.
  3. Place a bucket on the first or second step of the pool, spa or fountain without immersing (dipping) it.
  4. With a pencil, marker or electrical tape, mark the water level on the inside of the bucket.
  5. Shut off the pump and mark the pool, spa or fountain level on the outside of the bucket.
  6. Resume normal pump operation. Make sure that the auto fill valve is off during the test.
  7. After 24 hours, compare the two levels. If the pool water (outside mark) goes down more than the inside water level (inside mark), there may be a leak.

If it should rain during the timer you are doing your test, please repeat the test after the rain has stopped. It is best to check the weather before performing your test to avoid repeating the test. If you are unsure about how to do the test, Or having questions regarding the test, Contact Us for help.

If this happens, it may be a pressure-side return leak caused by the filter pump, backwash or waste line. Wet ground downhill from your pool and wet or soft spots on the pool side where the plumbing is may indicate a leak.


This may indicate a leak on the suction side or on the return lines bringing water from the pool to your pump. If there is air in the filter tank, air in the pump basket, or air bubbling out of the return lines, then it most likely means that there may be a leak?. You can use a marker or tape to measure and mark water levels to confirm water loss which is a indication of a leak.

Leak Detection in your pool is in Three Zones. There is the static part of the pool, the pool shell, and anything not involved in moving water to or from the pool. That will involve the lights, the sump in the bottom drain, and the liner if it’s a liner pool. The Second Zone is the suction side of the plumbing which is moving water from the pool to the equipment. The third zone is the pressure side, including the filter and anything that’s under pressure moving water back into the pool.

If there is a Leak on the Suction Side, it can’t leak when the pump is on. If it’s a Return line, it’s going to leak worse when the pump is on. If the Leak is in the shell of the pool, it will remain the same whether the pump is on or off. Observing Water Loss when the pump is on or off will indicate where to look for a leak.

If the Leak is in a plumbing line, Isolating the leak in a particular line from the various return lines usually involves using Leak Detection Plugs, then filling the line with water and air to see if whether or not the pressure drops. Once the line is identified, water and air is added the Leaktronics Pressure Rig; when air reaches the Leak, it makes a gurgling noise as it moves into water-saturated ground surrounding the pipe. Further testing of that line with Leaktronics Leak Detection equipment will pinpoint the exact location of the leak.

If the Leak is in the Pool, a DYE test is utilized, or a LEAKTRAC device is utilized for Liner Pools.

The first place to look for a Leak is in the pool structural penetrations; with light niches and skimmers being the most common starting points. Skimmers separating from a Pool structure as small as 64th of an inch become bigger over time.

A Swimming Pool Inspection isn't complete until it has had a proper leak detection performed. Visual inspections do not verify if a pool is losing water, and without a proper leak detection- Buyer Beware! Swimming pool repair can be costly, and the responsibility for repair(s) has to be discussed before a property changes owners.

Using the latest technologies by LeakTronics, we perform a non-inactive leak detection that will check the pool shell, drains and fittings, plumbing and pipes, skimmers, attached water features and spas to guarantee the potential new homeowner’s investment is sound.

See a video below of how a thorough and non-invasive leak detection is performed.


The weight of water pushing out of a leak creates a distinguishable sound. By listening inside the pool with sensitive hydrophones and by testing pipes and plumbing: we can accurately locate the source of your water leaks and recommend the best repair methods to stop those leak(s) and have your pool ready to enjoy without the concern of costly water loss.

Once your pool has been completely inspected, including a thorough leak detection we will deliver our findings in a comprehensive report with photos, and offer our best recommendation(s) for any necessary repair work to stop any leaks found, and ensure that the pool is a good investment for the buyer.
