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

This stands out very well when detecting leaks in water lines. I used it to locate an exit point for a drain pipe and it worked perfectly. Very fluorescent green color can’t miss it.

Just what I ordered

Very easy to use and effective. Very good value.

this looked cool in my fountain under black lights

It’s not really any cheaper to buy this stuff. It’s priced about the same. I have eye dropper bottles. It goes in those. I use it for dye tests (you only need a couple drops!) and for showing customers leaks in their toilets, showers, etc. It is super visible. It’s a good product and basically a lifetime supply of this stuff unless you have crews. Then they’ll use a bottle of this a week because they’ll waste it and spill it. Lol. In this case you need to order it once a week. Haha

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.

Easy, found & marked hot tub leak

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.

Very visible on the ground when I am doing septic inspections.
