What is the overall experience with leaking O-rings on tanks provided by dive Ops in Coz?
I am asking because my personal experience & observation with tanks from 2 different small boat dive Ops involved leaking O-rings for someone on just about every dive. (I am not exaggerating). Not necessarily with the tanks I was using, but with others on the boat, including the DM on one recent trip.
My personal experience with a leaking O-ring involved using my own regulator. (Nitrox dives) It was on our 1st dive. The 2nd dive was fine, so it was not my regulator. Also, I noticed that some, but not all of the O-rings were milky white in color suggesting polyurethane O-rings.
My understanding is that, with some exceptions, the Coz Ops all own the tanks they provide and they are all (or the majority) filled at the same filling station. I could be wrong about this. It is what I was told by a well-respected dive Op owner. (Or my understanding of what I was told...LOL!). Could the problem be worn or banged-up valves that need replacing? What QC controls are in place?
