DRAIN TRACING DYE 200g YELLOW HOROBIN

Drain Tracing Dye is used for detecting the flow of water in drains or pipes, identifying individual drain runs into a common gully, and tracing leaks in drains.
Green Dye contains 50% Flourescene.
The other colours are made from 100% food grade products.
The best method is to mix the Dye into a bucket of water, and then add to the flow of the drain. A 200 gram jar will trace up to 15,000 litres in chemical free water.
