Green Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

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!

does what it is suppose to do, turns water florescent green.

fast shipment , found leak quickly !

Great price and it did the job. Cheaper than a plumber!

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.

Found the tub leak, wasnt anywhere near where I thought it was. This contrast lead me to the culprit

Tracking simple and clear thanks to a well designed product, that dissipates within a decent interval without compromising on its stated purpose. It works!

Little expensive but it’s worth it. I didn’t use it for finding a leak. It served its purpose. Don’t get scared of the orange color when you get it because it will be green when you add it in water!

Used this to find a leak in a sewer pipe. This stuff is super bright with a black light even in direct sunlight. Made finding the leak a breeze.

Not much exciting to say about tracing die but it does it’s job as intended. Shipping was fast and efficient.
