My inflator hose is a 2 piece design. I can uncouple it in the middle of the hose and have an open end to use to fill and rinse the inside. on any BCD you can empty the air and submerge in a tub of fresh water then depress the deflate button or pull the dump valves and be able to fill enough to rinse. after rinsing hook up to a tank or orally add air before trying to empty. the air will help force the rinse water out. Then store with a little air in it.
