Green Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

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

Works great! Needed it to trace water flowing thru a drainage pipe located at the back our subdivisions run of homes. Helped identify where the blockage was to then water jet the blockage.

I was using this as a fluorescent marker and it worked great. I like that it is biodegradable and not nearly as nasty as some markers. the only drawback is that is looses capability as it dries. Not a show stopper from my perspective just something you have to be aware of.

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!

Worked well to find small pond leak. The warning label says that it is dangerous on your skin, so maybe a little toxic to humans. A little does go a long way. I used about a cup and could have used half that amount.

Does it work? Yes! Repeat customer here. If you want to see the flow at night, buy the recommended UV or blacklight flashlight. It does work! I already wrote a review for the first jug. See that also. We shared our first jug with neighbors, so got another one. It is not green in the jug, but dont be alarmed. It will Glow green. Daytime its a bright neon green. Nightime, use the flashlight I recommended above. Please note, it did stain our stamped concrete patio a little, but was worth it to find the stormwater runoff from uphill neighbor who re-graded the yard. Now the City is involved. Needed that proof.. green dye doesnt lie :)

Worked well. Dye takes several days to fade away. Our sump pump goes to our pond, so pond was neon green for a few days or a corner of it. Only takes a little bit to use, not entire gallon.

Worked great- saved me thousands in excavation fees.

We purchased this to confirm if our neighbors sewer was indeed leaking into our basement. They flushed it down their toilet and the green dye all over our basement was proof positive. Possibly saved a legal battle and a friend.

It worked as advertised.
