After looking at the prices of union valves in the hopes of making the plumbing removable it seems that it would be more cost effective to just replace part of the plubing again when I move the system.
If I make the runs of pipe a few inches longer under the bulkheads I will then be able to cut them and then repair the cut with a coupling after I move the tanks.
I went ahead and ordered some new bulkheads after deciding to chop off the old ones. The gaskets on the old ones looked somewhat worn so it seemed better to go ahead and replace them.
I also finished cleaning out the corner of the basement and set up the "stands". The middle will hold the sump underneath and the other two will serve as extra storage.
Now to do something about the plumbing. Time for another trip to the big orange box hardware store.
