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

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!

Easy to see in daylight. Used it to confirm patency of positive crawl space drain.

The liquid was not green at all, and was closer to a red black and totally useless.

Just what I ordered

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.

Just what I needed .

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

used it for halloween / a little goes a long way
