Not so high? OK, but not by much. The pressure wants to make a
cylindrical tank round. The ends usually are the first to go vs. a
longitudinal seam. The ends are flat. It usually goes _UP_ due to
years of sediment/scale inside resting on the bottom. Scale act as a
wonderful insulator causing advanced abuse/use on the bottom due to
overheating and loss of elasticity.

This is more typical:

Jeff,

Watts used to have a video of one set off above ground. Results were
similiar.
