![]() as for the thread, bad choice of where to drill it coupled with an unsupported bottom. all that don't support a tank with trim is bunk if you use a foam that will take out the irregularities it only adds to the strength and resistance to cracking. but bulkheads drilled along the middle are just bad, you can see the progression in the pic, the two closest to you started it and the shift caused the 3rd to be included. so you have an unsupported bottom, with rock pilled over the weakest point and nothing to resist the localized downward force.. at any rate a lot more heaters, overflows, ect have caused floods than tanks breaking because of being drilled. ![]() Steve
