Your swimming pool is filled with water. Because of this, a leak may occur just about anywhere on the interior or exterior of your pool. Don’t always assume that leaks come from your pool walls. You should first check your chlorinator, heater, filter, pump, and other pool accessories to see if they’re responsible for the leak.
As for inground swimming pools, they can still leak if they have an underground pipe that is cracked. In this case, you’ll need a professional pool technician to test the piping and see if a crack really does exist in it.
Sometimes evaporation causes a loss of water in pools too. You must make sure that evaporation is not the cause of your water loss. This is the first step.
You’ll need a large black magic marker and a plastic bucket (5-gallon capacity)
You’ll need a snorkel, red food coloring, and a pair of goggles with anti-fog and anti-leak properties.
If the leak comes from an area of the wall that is underneath the water, use goggles to find it and apply the food coloring the exact same way. Again, move slowly in the water because you don’t want the food coloring to run all over the place.
If you’re unable to detect where your pool leak is coming from, then don’t struggle with this task any further. Take the safer option by calling a professional and letting them deal with it.
