Worked well. Dye takes several days to fade away. Our sump pump goes to our pond, so pond was neon green for a few days or a corner of it. Only takes a little bit to use, not entire gallon.

The product was busted open and all over my driveway when I got home.

This stuff is great pour a bit into the washing machine to find out where it was leaking and sure it enough it helped me find it

I was luckily able to prove a city engineer wrong about old storm sewer connections that did not have any plans in the city files and save a lot of problems.

I needed to find out if water entering into house crawlspace was coming from downspout discharge. I poured some dye on the ground by the downspout and it showed up under the house with a UV flashlight.

I was able to mix a small amount and see exactly which drain tile was leaking. Saved me time and effort. Very easy to see even in low light.
