Dear Jon, when you place an atom at the screen pointer, there is no symmetry that Coot would be able to use. You need to tell Coot. One way is to merge it with an existing molecule that has a valid symmetry description. Another way is to create a separate PDB file with the symmetry of your choice and reload it. For all subsequent water molecules, you can follow Eugene's suggestion and merge new water molecules into your 'water-PDB'.
