Leakmaster Pool Leak Detection Kit – 8 oz Yellow Dye with Reusable Syringe – High-Visibility Leak Finder for Pools, Hot Tubs & Spas – 40+ Refills– Professional Water Tracing Tool

Pinpoint Leaks with Precision - Symptoms of a pool leak may include rising water bills, chemical imbalance, algae blooms, or cracks in structure. Our DIY leak detection kit helps you quickly identify the exact source of the leak in your in-ground pool, above-ground pool, or hot tub for faster repairs.

High-Visibility Dye for Easy Detection - Formulated with ultra-saturated color, our dye stays intact underwater and makes even small or slow-moving leaks visible. Dark blue dye contrasts with light backgrounds, while fluorescent yellow is ideal for dark surfaces or low-light conditions.

Refillable Syringe - Up to 40 Refills - Includes a prefilled 6ml syringe with precision extension straw for targeted application, plus an 8 oz refill bottle for up to 40 uses. Apply dye directly at the suspected site for accurate, repeatable testing.

Simple, Step-by-Step Use - Fill pool to normal level and turn off circulation. Discharge a small ribbon of dye about ¼ inch from the suspected leak. If a leak is present, the dye will visibly flow toward the leak site. Clean surfaces beforehand to prevent debris from masking results.
