The problem with water leaks is that the water quickly evaporates and will often leave no trace behind. Your water delivery system may be leaking water, but you may find it difficult to find out exactly where the water leak is coming from. One option is to introduce a water dye to the system that can allow you to identify the source of the leak and correct it.
Choose the Right Dye for Your Delivery System
Before purchasing the dye, read the label to learn about the suitable water delivery systems that can use the dye. If your delivery system is not listed, contact the manufacturer and describe your system in detail.
Select the Best Dye Type
Water leak dyes come in the form of tablets, powders, liquids or waxes. Liquids and tablets are easier to use because they can be dropped or poured into the water delivery system. Powders often need to be mixed with water. If you do not locate the leak after administering the dye, add more dye to the delivery system. Powders and liquids can usually be used more efficiently for larger delivery systems.
Use a Safe Dye Formula
For drinking water, the tablets should be non-toxic. All tablets should be non-corrosive to avoid damaging the water delivery system. Dyes should also not cause permanent stain and should instead break down. While temporary staining is an important part of using the dye, the stain should fade over time or wash away. They must be biodegradable, especially if used outdoors.
Pick the Right Color
Choose a dye color very different from the color scheme of your building. For example, if your building doesn't contain a lot of green, choose a green dye. Brighter dyes are more visible.
Look for the Circulated Dye
Fluorescent dyes emit light and should be chosen so that leaks become visible in the dark. Check fixtures and pipes for the fluorescent dye. When you find a dye stain, look for any slopes to determine the route of the water leak. Also, check above the dye stain for leaks.
Leak detection dyes are best used in combination with other water leak detection systems, such as water leak sensors. The sensors will generate a sound that will bring the leak problem to your attention in the first place. But even though you will know where your facility is moist, water leak dyes are likely the only way you will find the specific leak.
