Joe, Sounds like you have the Small Wonder central vac system. If so you can google the name and it will give you the website. If memory serves it is now part of the Dirty Devil group. The inlets or valves are typically the standard Broan, Nutone, Beam, Lamb, etc which can be purchase at most electrical wholesale or go to the web and order from a Dale Electric. The bags are still available from Small Wonder, 3 bags for $6.95 approximately. Ken
