Hey guys. I got a leaky Aqualung Calypso Primary reg. I changed the MP Seat and the crown and it still leaks a bit. Do you think it might be the spring that's weakened over the poppet or even the locknut? I'm stuck on this one.
Any help will be great, thanks
This is unfortunately a pretty common problem with the Calypso, especially with the 2010 - today models.
The components are so lousy and therefore there are so many problems that Aqualung had to offer the Calypso with the older model after one or two years.
The older Calypsos (2004 and later) had been to me the best fleet seconds of their times, the 2010 models are incredible crap and I don't get it why they are still on the market.
The problem why you cannot adjust the Calypso lays probably in the valve insert, reversible (part number 128606). That is the part where the poppet goes through.
The plastic (which is BS anyway) is so soft, that even after 50 - 100 dives the poppet has slightly cut into the plastic, leaving the orifice not perfect square anymore.
So the friction is increasing until the poppet does not move to its supposed position anymore. That's also the reason why usually the 2nd is not free flowing when you just turn on the tank valve. But one time pressing the purge button and it's not stopping anymore to slightly free flow anyway how you try to adjust the other components.
If you are lucky just some dirt or minerals are causing the friction and after ultrasonic cleaning it might be okay.
Chances are that it is the valve insert, and if you take it out you probably can see that the orifice is not square anymore, so you need to replace it.
Actually the same problems you might have with the older 2004 Classic model, but there the plastic of the so called Poppet Bearing ( part number 104134) is quite harder, so those problems occur much later (if at all).
I have always a number of either parts in my stock (just today I had to change again one those Valve Inserts).
So check if I might be right. Good luck
