Rated 5 out of 5 by from Excellent drain water tracer Used to trace water seepage in Victorian property cellar. Thought to be ground water, traced to leaking drain. Excellent product, bright green noticable even after 3 metres of ground travel.

Rated 5 out of 5 by from Brilliant Tried another well known brand before trying this one and found this one much better in keeping the colour and consistency in water that travelled some distance before coming out in my garden. Highly recommended.

Rated 5 out of 5 by from Good way to prove leak source I have two below ground rooms, a basement and a garage, both have had leak problems. With the basement I couldn't tell if the water was coming from the flower bed adjacent or from the water table rising, so I sprinkled some of the crystals in the flower bed when it was raining the pictures below show this is definitively where the water was coming from. When I dug the flowerbed out it soon became apparent there was 6 inches of rain water pipe missing (10p plastic cost £1000's in ruined wooden flooring. In the garage again I couldn't tell if the water was coming from surface water leaking in or from a rain water drain, I put the crystals in the drain and got a similar effect in the garage, will now claim on the water company insurance scheme. Don't get it on your hands, it will wash off but will mark everything you touch!
