Heylo Drain dye

The dyes are suitable for leak detection in drains and sewage systems. They are also excellent for finding leaks in flat roofs, terrace drains and underground garages.

The leak detection dyes red, green, blue and yellow can be detected visually without any aids. They are dissolved in water in the area to be tested and the water course to be examined is thus made visible.

The leak detection dye fluorescein/uranine is most clearly visible under infrared and ultraviolet light.

How to apply: The marking dye is dissolved in water (1 level teaspoon of dye for 10 litres of water). A lower or stronger colour intensity can be changed individually by using more or less dye.

Observe the safety data sheet and adhere to the recommended dosage.
