Rated 5 out of 5 by from Flourescein Drain Tracing Dye Use to ascertain outlet / position of drain & if it worked. Very long drain system (200m+), took time for water / dye to arrive at outlet, once found (overgrown). Initially couldn't find the outlet but heard the water before locating it & the dye. Ended up using the whole tub but the dye was clearly visible at the outlet. Would definitely use again. Only negative is all these dyes seem expensive.

Rated 5 out of 5 by from Great Product used to try & identify water ingress on a roof . Hardly any powder required to change water colour - only issue was description of how much to use was not easy to understand. we used 1/2 teaspoon in 10 litres , could probably have used less powder for that amount of water.

Is this safe for wildlife, if the drain runs to a ditch.

The linked safety pdf is not helpful, it only mentioned light colours and wavelengths.

Find a roof leak.

I have a leak in the roof of my property into the attic/loft space which I am struggling to locate the source of the leak. Could this product be used for this purpose?

Add it to the toilet tank

Hi Can you add this dye straight into a toilet/ tank and then flush to see if the drains are working properly? Also will it stain the toilet bowl? Thanks
Asked by: NHS123

toilet leak

Would this product show a leak at the toilet bowl waste pipe connection? Similarly would it show a leak from cistern to toilet bowl?

Where are the detailed instructions for this product?

You can download a safety leaflet but not details instructions. It refers to it being visible in Black Light but what do they mean by Black Light? If they mean it is visible in normal daylight why not say that? Is a special light needed?
Asked by: PhildItin
Black light is what makes a white t-shirt glow in a ghost train. A kind of deep purple light. I believe the product is the colour of a high vis vest anyway but with the aid of a black light torch, should glow and be very distinctive for tracing purposes.
