Pool Leak Detection Guide
Pool leaks can occur both in and outside of the pool. So, when checking for a pool leak, ensure that you check the entire filter system, which includes the heater, pump, filter, chlorinator, filter, etc.
If yours is an in-ground pool, then you should know that leaks can also occur through cracked piping on the underground. So if you see something suspicious indicating that there could be a leak, you need to get in touch with a local pool professional right away to inspect your pool for possible cracks.
For you to detect a pool leak, there are a number of steps you will have to go through. The very first step is to figure out if it is actually a leak that’s draining your pool and not due to water evaporation. Only when you confirm that it is indeed a leak, can you only proceed to the next step.
The Bucket Method
Basically, this is what you will need;
Step two, if you have the recirculating pump or any other auto-refill equipment in your pool, ensure that you turn them off.
Step three is where you wait for the results. You should wait for at least 24 hours and then compare the level of water in the pool and the bucket. If you find that the water level on the pool and in the pool remains the same, then know that the water loss is due to evaporation. But if the water level in the pool drops below the level in the bucket, then you may have a leak.
Repeat The Test
And since the first test may not convince you, or just want to narrow down on the possible leak sources or spots, you are advised to repeat the test with the pump for another 24 hrs.
Review The Results
If you find that the level of the water in the pool is more when there is low water circulation pressure, then the leak is somewhere in the pool plumbing.

Pool leak detection: Ink Method
What you need:
Doing this will help you determine the specific leak area. And since you know the leak height (the point where the water stopped draining), you should now be able to see the area as the pool wall or ground will be wet.
Before you apply the dye, narrow down on the leak spots. Once you have a clearer idea of where the leak spots could be, then you can go into the pool to find the exact spot using the dye.
Apply The Dye To Pinpoint The Leak
Once you find the exact spot, move in slowly without disturbing the water too much. Then squirt the dye to the wall. And if the leak is in that particular region, then the dye will start moving towards the source of the leak like a current.
But if the leak is not on the walls and you suspect it’s on the pool’s ground, just put on the goggles and perform the same process. Remember not to disturb the water too much as you don’t want the dye running wild.
Top 5 Most Common Pool Leaks
Pool Light Leaks
Having a pool leak around light fixtures in the pool is common as the unit it typically bolted to the shell, creating a surface that will eventually grow a leak.
While this isn’t as dangerous as one would think, it’s still important to repair water coming into an electrical light source before it becomes a hazard.
If your pool light has recently shorted out or there is obviously water inside the glass container, you need a professional repair.
Pool return fittings, and even the return line, are a common source of leaks as they aid in directing the water back to the skimmer or the floor drain. The return fitting is a plastic addition which does wear out over time, and the return line can also develop small cracks with constant pressurized water flow.
If you begin seeing bubbles coming from the return area, chances are air is coming in from a small leak.
Leaks below the skimmer, or even developing a pool leak in skimmer, is common as it is the part of the pool tied directly into the filtration system. The added pressure and constant vibrations can develop small, to even large, cracks and leaks over time.
One of the most obvious telltale signs is needing to add water to your pool regularly or even daily. While it can be one of the more costly repairs, having pool leak under skimmer areas is not something that should be taken lightly.
Not only does it waste water and drive your monthly utility bill higher, it can easily cause your system to run dry and prematurely burn out.
Drain and Suction Leaks
Having a main drain or pool suction line leak is hard to tell as it’s at the bottom of your pool’s surface. It can also be hard to identify as it has the most amount of water.
If your skimmer is not making a gasping noise and you are seeing a large amount of air bubbles springing up from the bottom, chances are it’s a main drain or suction line leak.
Suction Line and Pressure Leaks
With above ground leak detection services, we can determine whether the leak is coming from inside the pool, or if you have a swimming pool suction leak inside the equipment area.
In your filtration system, a suction side pool leak may be a relatively easy fix; usually all it needs is a little more grease, or a new rubber ring which prevents air from being sucked in.
If it is a pressure side return leak, that may be a little trickier to fix. Pressure areas leaks are in the plumbing that leads back to the pool. One of the symptoms to look for is knowing whether you have a pool leak when pump is on, or a pool leak with pump off.
If the pump is off and your pool loses water, it’s probably in the pool itself; if you lose water with the pump on, it’s probably in the filtration system.
If you do find that it’s a leak when the pump is on, one of the most obvious signs to look for is water trickling, dripping, or even spraying from the PVC tubing or from the system pump itself.
It may actually require a little bit of inspection work, as small leaks can be silent and can happen from inconvenient spots, such as from the side of the tubes that face the ground.
You can always carefully run your hand over the plastic surfaces and check for moisture. Also, if you happen to hear any “gasping” or “sucking” sounds near the system or tubing, it’s probably drawing in air.
