I hate the Anderson valve system. We had a new o ring replaced under factory warranty but a couple months later same problem: on city water our fresh water tank overfills. We have a Big Horn 2017 model. Why not do it like on my other RVs? Direct fill for fresh water. There are a gaggle of hoses behind the inlet lever which are confusing and could lead to leaks. We're going to try to bypass some of this and make a simpler system. I don't get why RV manufacturers (Heartland) make things worse rather than better. Bean counters?
