Is there a reason the vacuum breaker has to be that high . I have a 310RLS and its behind my shower . The lines go up to the shower are right above my furnace so that if it ever leaks that's where the water will go. I understand that the breaker needs to be at the highest point of the plumbing , but in this case the entire black flush line is only connected to city water and not to the rest of the RV plumbing . could i not just replumb to behind the nautilus panel ? on a side note i have already replumbed and removed and replaced all the vinyl tubing in my system with PEX except for the black flush line , so replumbing and moving will leave me zero vinyl tubing in the system unless there is some in the underbelly (a project for this winter)
