This is super easy to replace yourself in case your diaphragm gets damaged. Hopefully the reason is because it got stabbed by a sea urchin spike !!

Just make sure that if you have a retaining ring, that you put things back in the correct order. Reversing the order will cause the diaphragm to fold in your reg at the most inconvenient moment as you are working hard against a current.
