We have a 2011 Bighorn and have replaced the toilet with a composting toilet so our black tank sits empty. Taking the suggestion from the Wynn's (http://www.gonewiththewynns.com/product/valterra-t58-twist-on-waste-valve) we installed an external valve with the intention of closing it and opening both the bathroom tank and the empty black tank to allow the levels to equalize. However, nothing flows in the black tank!
Anyone have experience or insight?
