Water dye to debug water problem

[wacnstac]

I have a bit of water sitting and leaking from the bottom of the compartment where my grey and black water tanks are. This could be coming from:

a: water leaking from roof around wall to pan
b: a small water leak I have discovered plumbing in the rear access of the trailer
c: grey water tank
d: black water tank

I'd like to put some different colored water in the grey and black water tanks to to rule them out (sure would feel good to rule these out). Can anybody recommend a dye that would be safe on the plumbing that would get this done for me?

I just use food coloring. Use a white paper towel to dab up the leak and you can see the color easier.

I swear if it's one of my tanks that is leaking I am done with this thing!

You can also buy Easter egg coloring kits. I hope it's not a tank. Depending on the material it can be a fairly simple repair job.

If you pull an Easter egg out of the black tank , PUT IT BACK!

I think I found the source of my water down there. It is pouring in at the seam of the bumper and back end of the trailer.

Nope, just filled both tanks tonight and water is dripping from the behind after it was dry all day. Just dumped the grey water tank. Put food coloring in the black water tank. If that's the leaker I think I'm done with this thing! Can't pour any more time or money into it.

Anybody have any idea what it would cost to take something like this in and get repaired (if they'd even look at a 79?). It's the black water tank to make things even worse. Now I'm not sure if the tank is leaking or if it can leak at the valve into the pan. I'm afraid to start loosening the bolts that hold the belly on in that area as I bet they will all shear off.
