We store and dispose of nuclear and chemical waste in our sewer drain so I don't foresee any issues.....j/k
But seriously, any general advice about these things? What do they look for exactly?
For instance, we have a Fork-truck that's been leaking hydraulic fluid for the last two weeks (while our normal truck is being repaired) onto our factory floor. Is this going to wig them out? I have no idea how these things go.
FWIW, the fork-truck that is leaking has a scratch in the main mast cylinder and it would cost more to repair it than to replace the truck is worth. If it were a line or something we would have fixed it. We are only using it while the tranny ion our normal truck is being rebuilt.
