After developing a leak in our grey tank several years ago, and was able to repair it with a Plastmend kit, I decided the cause of the leak was due to the bottom of the tank flexing with the weight of water as it filled. I installed two extra braces along with the two that already were installed, I suppose to support the weight of the coroplast, glued varying thicknesses of blocks to the bottom of the grey and black tanks so the braces would contact the blocks after the coroplast was reinstalled and the braces were also reinstalled. Now, the actual weight of the tanks filled with waste is supported by the braces, not the lips of the tanks. I think I've read that the tank manufacturers specify that the lips should not be used alone to support the tanks. We can now dry camp and have the tanks completely full prior to dumping or having a pump out without worrying about having a tank break.
