According to, the search process involves cleaning the equipment area, inspecting the pool area for signs of wetness, turning the pump on and inspecting the skimmer and the return piping system at the wall.

Check the Pool Equipment 

Checking the pool equipment for signs of leaks should not be overlooked because the leak may be outside the pool area. Turning the pump on can reveal if the leak is on the pump or the pool tub.

The skimmer and return system at the wall should be thoroughly inspected as these locations are prone to developing leaks.

Be sure to check the outside of the pool for any leaks before checking the inside. An outside leak should be obvious and easy to find. ​You need to check the bottom of the pool as well and looks for signs of excessive wetness.

Finding Leaks in the Pool Liner​

The leaks normally come out in the form of moisture. Finding a leak in the vinyl liner can be very difficult. The following steps will help you locate the leaks:

  • Turn the pool pump off and allow water to stay still – doing this will allow you to check and analyze the bottom of the water more clearly. Take time to check the bottom of the vinyl for water pools and streams.
  • Check the perimeter of the pool– the areas of consideration include the mulch and the walls at the bottom of the pool. Excessive wetness could be a sign of leak, but be careful do not confuse leaks with natural ground moisture.
  • Clean the pool before getting in – get inside the pool and inspect it for signs of leaks. To do this effectively, you need to clean and vacuum the pool. Cleaning the pool will eliminate dirt blocking your visibility

The Color Dye Method

The equipment needed for this exercise includes a snorkel, swim goggles and food coloring dye.

Swim to the areas where you suspect the leak to be and start squirting the dye around.   Squirt the dye near the wall where you suspect a leak and see if the dye moves toward the hole.

For the bottom of the pool, you do the same thing but just use your goggles to swim around and squirt the dye.
