A dye test is one way to investigate swimming pool leaks. Red, yellow and blue dyes are used to find a pool leak in the surface of a pool or spa tub. The red dye is the most common, while a fluorescent yellow dye can be used for a dark painted surface. The blue dye is used on light colored pool surfaces.

How The Dye Test Works

A dye test works for pool leak detection because the concentrated dye is heavier than the water. A leak detection professional applies the dye with a syringe close to the area where they suspect a spa tub or swimming pool leak.

Turn off the pool pump so you are working with still water. It's important to have precise dye placement to identify leaks wherever they are located. When a leak is present, the color will be sucked into the pool wall crack or fissure causing the leak. The dye identifies the area and the water movement into the fissure. All dye colors will eventually dissipate in the water.

Dyes work on all pool surfaces, including vinyl, fiberglass, and gunite or cement. Fluorescent yellow dye will work well on the vinyl pool with a dark blue surface. The pool can be in-ground or the above-ground style in a frame.

In addition to using this process to find surface leaks on pool tiles, a leak specialist can use dye to identify water loss around a spa or pool's drain, skimmer, and fittings pass inspection. With an obvious leak, the crack or fissure may be felt rather than seen by an experienced leak detection technician who knows what to look for in the water. However, it's still helpful to confirm with dye.

Repairing Swimming Pool and Spa Tub Leaks

A leaking pool can saturate the ground around it and cause problems with the skimmer and pump system. Therefore, it is important to fill the cracks as soon as you detect a leak. This can be done without draining the pool.

You can apply a special patch to a vinyl pool lining if the material tears. This must be done immediately to prevent the tear from spreading. Vinyl is very susceptible to tears that can cause a swimming pool leak.

If you have an inground pool, a professional will use special epoxy fillings to repair leaky fiberglass and concrete pool issues. Gunite, a concrete and sand mix, is very durable and cracks in the surface are rare. Nevertheless, older swimming pools can have small surface cracks that can lead to bigger problems. A quick setting epoxy can be used underwater to fix cracks and areas where fittings have pulled away from the surface.
