Green Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

I had an issue in which one of the waste pipes within a house underneath the basement slab was cracked and was leaking into the french drain and ending up in the sump pit. To isolate the source, I added a small amount (4 ozs) of this tracing dye to a 5-gallon bucket of water. This stuff is orange in the bottle, but wildly flourescent yellow-green when mixed with water. It worked fantastically well, and we quickly isolated the source. Following the directions, we had also purchased a UV blacklight to more easily see the colored solution in the sump pit, but in our case, it was so obvious -- and so yellowy-green -- that we didnt really need that UV blacklight. FYI, the seller was very prompt with delivery and we received this without any leaks. For this particular application, I highly recommend it.

This product worked perfectly for exactly what its intended to do. We used it to test the effectiveness of our septic system. It was shipped in a timely manor and service was great. It did arrive with a crack in the lid, but there was no leak, and since it was packaged in plastic it wouldnt have been too messy if it did leak. Overall were satisfied! Thanks!

Not sure if I was unlucky with my batch, but my UV light and black light both failed to properly light up the liquid diluted in water (at a ratio that was more concentrated than suggested). While the yellow colour was very bright and fluorescent in colour when in the tub, the inability to light up under UV light meant that it was all but invisible on concrete (colour would not show after momentarily flowing over a concrete slab I tested on). Product works fine if you just want the colour, but would NOT RECOMMEND if you want the fluorescent properties. The cap was also cracked on arrival (but thankfully there was an inner seal. It just means I can not fully tighten and close the cap now and must keep it upright.

DWV line testing. I found a couple leaks using it that I wouldve never found without it. Note: Using a black light really helped illuminate it.

Thank you!

I was luckily able to prove a city engineer wrong about old storm sewer connections that did not have any plans in the city files and save a lot of problems.

It works...I guess. I used this to try and find a leak in my septic system. I even bought a UV light and thought I saw some. Turns out it was just the UV light in the water. I would try red to show up better in the yard.

When my sons truck began to have radiator fluid leak issues, we tried to find the problem area but there was so much gunk on the engine block, it was difficult to tell. We put some of this fluid in the radiator (dont need to use much) and started the truck, then used an inexpensive UV light to see where the leak was. Worked like a charm!

I used this green tracing dye to dye our 5,000 gallon fountain green for St. Patricks Day since I read this is what they use at the white house fountains since it wont stain the stone in the fountain. It worked great. It took about 1/3 of a gallon for the fountain to turn fluorescent green (see picture). Day two and it still looks the same with no stains to the stone.

What a mess. The bottle was broken in the box and got on my other purchases. Plus it did not work.
