Your pool will naturally lose some water to evaporation, some to splash out and some to backwash waste-water. You may also gain water from rainfall. Our rule of thumb is, if you’ve lost more than 1/4-inch during a 24 hour period, you’ll need to perform a pool leak detection procedure and apply pool leak repair methods to address any leaks in skimmers, return lines, lights and drains and/or cracks in the pool masonry.

Pools are meant to be watertight, of course, but sealants will deteriorate, while other parts of your pool shift and settle, or just plain wear out. Pools can leak through any of the fittings or accessories, plumbing or even right through the shell. It is important to repair pool leaks, not only to save water, heat and chemicals, but also to prevent undermining pool structural components, and washing away fill dirt.

Caltech Pools detects leaks in your swimming pools by using our very own, state-of-the-art electronic leak detection technology; LeakTronics.  With LeakTronics, detection of pool water leaks has taken a quantum leap ahead of traditional, time-consuming methods such as water dyes, divers and air pressure tests.  We can pick up pool leak sounds using submersible waterproof microphones.  All pool water leaks produce an underwater sound signature which we can find & monitor with our headphones.

Our process is further confirmed by adding dye to the water immediately opposite the microphone position and visually observe the suction action of the swimming pool leak using a micro-video scope. As dye is injected into the water, the exact location of a swimming pool leak inside a line is easily identifiable as the video camera reveals the dye being sucked into the leak.
