I need an advice regarding a similar problem. A week ago my instructor found out that my new Scubapro x650 had been soaked for about 20 minutes without the protective cap. My instructor is also the owner of the shop who sold me the regulator and he is also the one who is doing servicing of Scubapro and Poseidon regulators at the shop so he should know something about regulators. He also have about 30 years of diving experience.
Anyway, I asked him if the regulator was damaged. He told me that it should be fine although he advised me not to soak or rinse without the protective cap again as water may lead to washing out lubricants. He did NOT dry the regulator by putting it on a tank and running air through it. He just handed it back to me and when I kept asking him about it he insisted that I shouldn’t worry that this one accident will damage a well engineered product such as the x650.
The next morning I dived for 68 minutes at about 9m with the regulator. My question is if all the air that went through the regulator during the next morning was enough to dry the first stage and the hoses completely? Also, what about water in the hose of the octopus? Since I didn’t use the octopus then is it possible that water in the hose of the octopus didn’t dry (if there was any)? I became more worried after I read in this forum about the drying procedure in such cases, which my instructor didn’t do. So, should I worry that not drying the regulator as described above will lead to damage?
