I don't really think they care. The tanks have been improperly installed for years and tanks have split and broke in various ways, all due to being supported only by the lips at the top of the tanks, when the tank manufacturers say they should be supported from underneath. We had a leak in our grey tank and I was able to repair the crack instead of replacing the tank, and to avoid another incident of some other failure to either the grey tank or the black, I added supports under both the tanks, and now do not worry about them breaking or falling from where they are mounted. After I completed adding additional supports, I removed the braces, reinstalled the coroplast, and then reinstalled the braces.
