First, you don't disconnect the tubes, you lock the valve block off, and remove it from the motorhead. That keeps the tubing from leaking. In any case, it sounds like you need a new o ring for the motorhead too. Every time you maintain the filter, it is advised to put a thin smear of silicone lubricant on this o ring to prevent it from drying out and shrinking. It may look fine to the naked eye, but could have shrunk. Maintenance should be every month to two months. It may have dry rotted too, as we have not manufactured the C Series in about two years, so if you have had it only 6 months, it sat on a shelf somewhere for a bit. Since you have not had the filter very long, we would be happy to help you out. Please call 1-800-322-1266.
