I have a late '70's MK5 that I recently sent in for routine service, and it ended up being returned to me marked as "unserviceable", due to a bad piston. I thought that to be a very vague explanation so I called the service center for a better answer and what I got was that they were unable to get the intermediate pressure to stabilize, due to the piston being bad, whether from a worn knife edge, or any other slight deformity. Apparently Scubapro has discontinued support for the MK5 first stage and the replacement piston is not available. I thought I was SOL until I came across a MK5 piston for sale on ebay that was rescued from an old dive shop. I called the service center back to let them know I had a replacement piston and I was told they still cannot service it since the part didn't come from Scubapro and they don't know it's history, valid point I thought.
Anyway, I've since thought maybe I'd have better luck taking it to a different shop. Is this a waste of time, and should I just cave and replace my 35+ year old reg? Has anyone else experienced similar issues?
