Pool skimmer boxes sit at the waterline and take the brunt of thermal expansion, soil shifting, and deck movement. The plastic skimmer throat is set into concrete gunite, making the seam prone to hairline fractures.
How Syringe Dye Testing Locates Skimmer Leaks
With the pool pump turned off and water completely calm, our technician lowers a calibrated syringe containing concentrated fluorescent yellow-red leak detection dye near the skimmer faceplate and perimeter seams. If a hairline crack exists, the water escaping creates a suction vortex that visibly draws the dye right into the fissure.
Two-Part Structural Underwater Epoxy Sealing
Once identified, high-strength underwater structural epoxy compounds seal the crack without needing to drain thousands of gallons of municipal water.
