How Does a Dye Test Help in Detecting Pool Leaks?

If you’ve noticed your pool water level dropping faster than normal, you might be dealing with a leak. One of the simplest and most effective ways to pinpoint the source is through a dye test. This method helps detect leaks by visually showing where water is escaping from your pool. A dye test involves using a special leak detection dye around suspected areas—such as cracks, fittings, lights, main drains, skimmers, or return jets. The pool’s circulation system must be turned off so the water remains still. Once the dye is released near the suspected area, it behaves like smoke in the air: if there’s a leak, the dye will be pulled toward and into the opening, revealing the exact location of the problem. This simple test can confirm whether water loss is due to a structural crack, plumbing issue, or faulty seal rather than evaporation. It’s a cost-effective first step before more advanced leak detection methods are needed. At Coastal Pool Restoration, we use dye testing as part of our professional leak detection process to save you time, water, and unnecessary repairs. Identifying the leak early helps prevent bigger issues—like surface damage or equipment failure—down the road. Think your pool might have a leak? Don’t wait for small cracks to become big problems. Contact Coastal Pool Restoration, proudly serving the Grand Strand and surrounding areas, to schedule a professional inspection and keep your pool watertight and worry-free.
