There needs to be some clarity describing how to get placement properly.

After a ton of trial/error in sandbox, the ground in the water needs to be at least -2 flat (-3 visually if sloped out)

This is confusing on maps where the default terrain is +4 as the depth means the pier walls are unstable and will collapse.

While the vanilla pump/dump has the same limits, it's less obvious as it's further from the coast line.

Recommend putting the -2 height requirement in the tooltips and on the mod page
