I read somewhere it may have been here or in another website about a little plastic "pop-up" vent that you clip into your pouch at the rear near the top and can then be used if and when the charcoal vent blocks up which I found happened a lot when I would attempt to flush the pouch out. Does anyone out there know or have heard of these things and if so where are they available from. Be nice if they exist and are available in Australia. Thank you in advance to you all, regards,
Tom.
