Green Water Tracing & Leak Detection Flourescent Dye - 1 Gallon

Works great, especially when it makes contact with water.

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

DWV line testing. I found a couple leaks using it that I wouldve never found without it. Note: Using a black light really helped illuminate it.

I am unsure where my previous review went, however here is an update: When I received the item the color of the dye was orange. The label is as pictured but the color of the dye in the bottle is definitely orange. It will also stain your clothes that color of orange. After pouring the orange liquid into your drains and dissolving/mixing it with water it will turn the brightest green you have ever seen. I used it to test flows for french as well as finding downspout drains. Works excellently! Will buy again. Seller is top notch!

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.

Little expensive but it’s worth it. I didn’t use it for finding a leak. It served its purpose. Don’t get scared of the orange color when you get it because it will be green when you add it in water!

I bought both the Red and the Green Dye for a project in which I was going to utilize a blacklight to make water glow. The green worked just fine. The red (which was more dull pink in color) did NOT glow under a blacklight. I dont know why. The green is ok.

Used it in my yard to do 2 things....first to locate and underground drain tile that went from the backyard to some where in the front yard. Worked perfect. And at the same time poured small amounts around the backyard during a rain storm to identify the water flow across the yard in preparation for installation of drain to feed to the newly discovered existing drain. Used in a commercial project to locate leaks in a water feature. Again worked perfectly. Have used both the red and green but like the green better. Much brighter, no light needed.

It works

Works great! Needed it to trace water flowing thru a drainage pipe located at the back our subdivisions run of homes. Helped identify where the blockage was to then water jet the blockage.
