I had the vacuum breaker that is in line to the black tank flush break and flood the place, water started coming out everywhere. Unfortunately it also flooded the furnace and the fan started running, I think it fryed the mother board. My problem is I cant seem to find a replacement vacuum breaker. I thought I read somewhere that Home Depot or Lowes might have them, there is a severe shortage of RV dealers here in the Lake of the Ozarks. I would appreciate any help that can be given.
