How cold is too cold to dive in a pool for pool leak detections?

As winter weather comes to Texas, pools start to run into problems, especially pool leaks. The fluctuations between sunny and warm to really cold can play a major factor in pools losing water either naturally or through other issues with the pipe and equipment.

Normally for pool leak detections, we dive into the pool to test lights, main drains as well as review the shell of the pool and perform underwater dye testing. When the weather drops, we have to be cautious about entering cold water or coming out of the water into cold temperatures to maintain the safety of our team, even though we use wet suits.

If the water temperature is 60 degrees or below, we will not dive into the pool to test for leaks or perform inspections. We are still able to perform a number of leak detection activities, but diving into the pool is not done once the water temperature hits 60 degrees or below. This is simply a safety issues as many times we will be under the water for 30 minutes or more at a time, and in the water overall for a couple of hours.
