Hey y’all. I have a 2016 Entegra Aspire. It won’t gravity dump on either tank and only dumps when macerator is engaged. Today I pulled the hose out a little and realized the pvc pipe goes up. No wonder it will never gravity dump. Is this a normal setup? I’m second owner. (See photo) the pipe came loose today and sprayed gray water all over. Luckily it was gray. Still nasty!
