If your refering to what I posted then I am talking about the lever opening and dumping water out of the hoses when its not attached to the canister. Its not like there loose or anything, but pretty easy, and I am overeacting.
Edit> since this post has been resurrected I will make a correction. I never realized the level actually locks off when removed, no chance of accidentally releasing the water flow when its off the canister. Silly me.
