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 :)

Dumped it into a pool to find the slow leak I had,,, it ONLY made the whole pool discolored and ugly

Not working properly. Hardly see it from the wastewater.

Solved my problem!

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.

One of the bottles came WITHOUT a cap. Only the foil seal prevented a huge mess in transport.

Arrived very quickly. Used small amount on a suspicious area on my tile over concrete deck. In a very short time cofirmed that rain water was traveling from that area, under the tile into my house. Worked perfectly.

Did exactly what we wanted, helped me trace where an old cistern was discharging to (our sump pit) worked immediately. Just what we needed to solve our problem.

This stuff is great pour a bit into the washing machine to find out where it was leaking and sure it enough it helped me find it

Worked great- saved me thousands in excavation fees.
