I tried to have a day off today. After 4 calls in the morning, one of which told me that the Coltri Sub compressor on our dive boat, which we had just fixed having a bad second stage intake valve, which then blew out the gasket just over and between the first stage intake and exhaust valves, I decided that a day off was not in my immediate near future.
I went to the MV Saifon, Adventure Divers boat, and sure enough, after three straight days of big and small problems, it hasn’t gotten better. I started the Coltri Sub and the same symptoms as a week ago were there. The third stage piston, a free piston, driven closed by a push from the push rod, but driven open by pressure alone, was clattering, meaning that in the third stage there is not enough pressure to drive it open.
Right now, being completely bored with these continuous problems, hope to get Steve, from Easy Tek, to come out to the boat and remove the offending compressor to fix it and to install one that he has in his shop that he uses for training purposes.
