I don't know anyone who hasn't wandered into the water with their relief zipper open at least once. It took me two times to really learn the lesson. (I use a lowered pzip.)
My personal dry suit advice - before launching walk into the water and immerse up to the neck. In addition for checking things like open zippers, it is also the easiest way to burp your suit and to figure out if you need to add or delete layers.
