Rated 5 out of 5 by from Great product, use sparingly A really useul tool for finding leaks and water connections. Used it to trace a leaking drain, and it saved me a load of unnecessary work. Use it sparingly, you don't need much to see the water colouration.

Rated 5 out of 5 by from Great product Bought this to Trace the drains for a customer so I could run the waste for a new kitchen into the correct drain. Wow it coloured the water great when I poured the water into the drain it was easy to see it going into the right manhole! And there are lots left for another day great product thanks Screwfix!

Rated 5 out of 5 by from Best dye in the office So much better than previous dyes I have experienced. It showed me the direction of flow in the pipe with such confidence that I was able to carry out my job feeling that I had developed a bond with this dye, and would totally have it as my wingman on a night out. Would recommend to all those who need a dye in their life.
