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

It works!

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

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.

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.
