Regulator free flow issue

[Saboteur]

Hi all. Yesterday while gearing up for the morning dives my octo started free flowing. We attempted to switch it to one of the dive boats octo's with the same result. I took it in to a dive shop and he checked the IP, which he said was off the scale. The set up is a Zeagle Envoy II with Oceanic Swiv octo, it is about a year and a half old with about 60 dives on it. I had it the reg looked over and the IP checked (not serviced) before I left and the IP was right on spec. Its been working fine on my monthly pool dives and for the first week of this trip. l'll get it looked at back home at my LDS, but for my own knowledge what sort of things can cause the sudden problem. Thanks.

The HP seat has failed.
Probably no particular reason why it's failed.

I had a HP seat fail on a weeks trip earlier in the year. Luckily we had a spare first stage in the group that I could borrow, only lost the one dive whilst I swapped it out.

Like other manufacturers Zeagle has had defective high pressure seats in the past and this failure sounds like the high pressure seat.

It could be the HP seat but it could also be one of couple different orings. No real way to tell until you get it apart. That is the reason I carry a spare reg, stuff happens.

Thanks for the info, much appreciated.

Yet another reason I advocate having an IP gauge and regularly checking what is going on within your set (not saying anything against the OP - obviously he did have it checked and it passed). This seems like it was a sudden failure but maybe the gauge would have seen a creep developing before it let go. Having a spare 1st & 2nd is always good insurance especially on a big trip.
