5. Plumb the Shower Column
Using a level, check the position of the shower column to ensure
it is plumb.
The upper mounting collar is adjustable to account for plumb and
wall surface offset. Turn the mounting collar until the shower
column is plumb.
Verify that the mounting collar slots align with the pencil
markings on the finished wall. Make any adjustments as needed.
Remove the shower column from the supply adapter.
