Green Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

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 :)

works

Have only run a few sample tests, but it definitely turns the water green and can be seen pretty well with a UV light. I only used a few drops in a gallon of water, and that worked pretty well. Want to run a few more tests before trying to figure out leakages in a water feature and fish pond. So far, so good.

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.

small amount identified water flow and it cleared quickly........

Did what it was supposed to do. Located the leak quite easily. Good product.

Works very well. Have used on several jobs.

We had a leak in our 4500 gallon pond. Once we were not able to detect the leak on our own we sought this product out. However we tried using it several times and were unable to locate the leak. Partially because the fish once you pour the liquid in just kept moving around and messing everything up. We have about 30 fish in our pond so it wasn’t easy to just remove them. The product didn’t hurt them at all whatsoever. We ended up having to buy a new pond liner and pull the fish out and replace the liner. I feel as if this product is much better for plumbing leaks.

We have a drainage issue on the property with a retention area that has been draining very slowly and we didn’t know where it drained out. I used 2 cups over the area where the water is supposed to drain from, and in a few minutes we found the drainage pipe where the water exited about 200 hundred yards down the road.

Worked great- saved me thousands in excavation fees.
