Water dye to debug water problem
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?
