I have a 2019 3120RL. Have had the cable pull for black tank fail twice. Last time I was in a hurry - tech opened black tank gate and just left it open - I have a knife valve at the end of sewer line. Not the way I want to continue. Obviously the cable is part of problem - it will no move. Any suggestions as to a permanent fix. I do not wish to leave it open nor do I need techs coming to my campsite to try fixing the issue. I there a better solution than the pull cables.

Thanks Brian
