Has anyone replaced their guillotine waste valves? I believe my gray tank valve is not opening when I pull the handle out. It may just be a sensor error, but just in case, is this a difficult task on a classic 2015 Anthem. There are youtube videos available online, not Entegra specific, but I'd like to hear from an Entegra owner. Can the handle and stem become disengaged from the guillotine mechanism? If anyone has replaced theirs, is there a recommended part number to use?
Thanks, Jim
