I have what I think is called a "vacuum break" leaking water. It is connected into the black tank flush water line. I don't really understand why, but the vacuum break is installed behind my shower at nearly the height of my shower valves. They have run a water line from the hookup side clear across the trailer and up behind the shower to install this thing. I have a 3650 and the shower is on the starboard side (that is if port is left and starboard is right, never been quite sure about that). It certainly is not easy to access. Anyway, when I shut water off on the black tank flush, water begins dripping out of the vacuum break thingy. I suppose this thing is installed to prevent any yuck water from getting into potable water. I would like to simply eliminate the vacuum break but am I then risking contamination of my potable water?
This may not be related but when I unhook my hose from the black flush hookup, some water drains back out of the lines. I've wondered if this backflow of water is opening the vacuum break causing it to leak. Should there be a one way valve at that hookup to prevent backflow?
I have included a fuzzy picture of the problem part. It's hard to focus when holding the camera down into a dark hole.
TIA for any responses.
