Green Tracing Dye - Highly Visible Concentrated Fluorescent Leak Detection Dye - 1 Gallon

We actually bought this tracing dye to turn our pond green for St. Patrick’s Day. It worked perfectly, the color lasted a few days and it was great for the occasion.

Worked exactly as expected. Was able to find the water seeping into my yard was from the septic system. Did take a little longer to show them thought, but when it did it was very noticeable.

Easy, found & marked hot tub leak

Good stuff

This product proved conclusively that during a heavy rain water flowing under my land from a road catch basin had long ago found a way out of an apparently broken drain pipe and caused a large cave-in on my driveway. Hole is 40 inches wide and 40 inches deep, and also extends an unknown distance under the asphalt that is still intact. My town cannot dispute the results and will remedy the situation and repair my driveway. The photo shows the green dye just arriving in the big hole several minutes after I poured some into the catch basin on the road during a heavy rain.

It worked as advertised. I did not know it would take so long for it to appear at the discharge line of my septic system.

This worked as we thought a a little bit goes a long way be sure to wear gloves when pouring.

Still havent found the drains. It does stain heavily so be careful not to spill or get it on your hands. Takes a long time to wear off! May work better for othera needs not so much for ours. We wanted to know wherw are down spouts and floor drains led and.atill no.clue.

great for verification of under ground utilities

Used to trace were drainage was leaking from. Did a good job. Easy to follow. Last for days . Maybe have used to much but worked well.
