In your first post in this thread you asked:

Is it assuming there is pressure on top of the bulkhead or not?

The correct response from me should have been:
Hell no! There is no pressure on a drain bulkhead! Only the weight of any water that is on top of it.(Weight and pressure are two totaly different things.)

My reply with the word "probably" was just a nice way of saying "No pressure....... Only weight."

BTW, there's nothing wrong with this calculator IMO.
