Here is my 6.9l pressure vessel. just refilled as no longer window cleaning. i baught this last year. i know that the ones you buy are just over half filled. this one is as full as i could get it so the resin inside is brand new. the container is approaching a year old. regular hose fittings the resin i use is in the picture. i kept this 6.9 ltr as a backup because once or twice, my reading were zero but as the vessel approaches empty it can happen mid day and i left a customers house with a few spots so i got something that i could just switch to to safe going home midday.
