So I filled it with saniclean, emptied by opening up and pouring out. I usually push all the saniclean out to purge it but I was trying to conserve CO2. Then began racking from the carboy. I did see some air bubbles at the end. I also detached the hose from the lid, opened it up and just put the hose in the keg at the end but it was just a trickle coming out, and that is when I switched to the racking cane. I had the PSI cranked up to 10 at one point, I usually set it at 3 PSI for this. Maybe it was clogged, I don't know.
