Water fountain with leak detection dye - GIF

[hemmjo]

I have several packs of old Sea Marker Dye.


We used it just yesterday to find an old plugged up field tile at my daughters place.

Dropped a pack in the standing water at a drain in the woods.


Waited a while then started looking "down hill" Found it oozing out of the ground
in a swale, across two other properties, about 400-500 feet away.
That is muddy green dye in the center.


Then started walking back toward the drain and found two blow-outs with green water in them.


Now we know there the drain is, we need to try opening it up a bit.
