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

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.

So easy to use … no mess and brute color

This product was easy to use.

I used this product to track down a leak in my lawn sprinkler system and it only took about 10 minutes to track down the problem and replace the broken pipe. I would recommend this product. It did the job and didnt kill any plants or grass.
