Green Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

I had to use the whole gallon to trace the leach field of my septic system.

Great product

Worked well for our purpose

Works Great

Found my back yard septic leak easy, targeted the area fix instead of digging up the entire drain field. Used a quart out of a gallon. Flush it and wait overnight, pretty easy to see.

Great product use mine for underwater leak detection. Great visibility in low light area

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.

Easy to use

Good

Traced a septic outlet. Took a few hours for dye to reach outlet, but was very evident when it finally emerged.
