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

Suspected a sewer plumbing break because black water was making to my dump pump. Poured 1/2 a gallon of the dye into the kitchen sink. Day later my sump pump pit was green like the Chicago waterways on St. Patty’s day. Stuff works!

Tracing pipes

Just what I needed .

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.

Worked perfectly for my Halloween display. Color was great.

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.

Worked great! I needed to trace where the water bubbling up in my lawn was coming from. Unlike other septic dyes, this was very visible and unmistakeable.

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.

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.
