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

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.

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 looked cool in my fountain under black lights

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.

Just what I needed .

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.

Good stuff

Works great and highly concentrated. Also a very good value compared to the supply houses.

Fantastic non-toxic product!! I put in small containers with eyedroppers and put in a plumbing service truck for dye testing toilets and other plumbing service issues. Three or four drops of this in a toilet will get the job done better than 1/3 of a bottle of food coloring. So glad I found this non-toxic product, make me less nervous about kids or pets while Im working in someones home.

Used to find where water was flowing into sump pit from lake. This worked beautifully and was easy to see.
