Open or Closed???
How do others handle the black water discharge at full hook-up campgrounds? My thought was to keep it closed until it is fairly full so the chemicals have a chance to break down the solids. I've spoken to others who leave it open. Would leaving it open cause a problem of the solids building up in the tank without ever being broken down or is the tank shaped in such a way that everything goes out on every flush?
Sorry for the indelicate subject, but we are doing our first long term camping trip and I've never had this question before.
