I have an new Mares BC. I cant remember the exact modle but its about 2yrs old. Anyway I bought a Zeagle OCTO+ Octopus/Inflater to install on my my Mares BCD. In order to remove the old Ergo Inflater that came with my Mares I had to cut the cord that went to the release valve at the top of the Corrugated Hose. I was then able to remove the old inflater and install the Zeagle OCTO +. It seems to work but it dosen't Purge the air out of the BC like the Original Valve did. In fact it seems Like I will have to sqeeze the BC a Little for it to Vent. Is this how a properly installed octo/Inflater should work or was there some way to attach the cord connecting to the valve to my new Octo? Any Info would be greatly appreciated.
