I don't want any part of my fresh water tied in with my tank flush. If your backflow sticks on the black tank flush you contaminate the whole trailer.

Agree, don’t think whomever did that understood the ramifications of that setup.

Not to mention using up filter life filtering your black tank flush water.

Where did you see this?
It appears that he is sending filtered water to the black tank flusher? There are a couple of other items that I cannot determine what they do?

The ones I have seen use an air gap design.....Pretty safe...... But still, I wouldn't do it.

It was on a FB RV group...I refrained from comment. The guy was proud of the clean install (I'll give him that) but indignant toward the onslaught naysayers...

This isnt even the concern. Without having a path for the "clean" water part of the black flush to drain back out, the vacuum breaker wont ever do its job and it might as well not be installed. It would be a concern when the tank is full or at least fuller than where the flush line enters the tank and then bacteria can slowly work it's way up the line. Probably wont hurt anyone, but certainly not the most sanitary type of installation.

+1 what @FT4NOW said above.

I use the same hose for fresh water and black flush water, but the main reason I'm comfortable doing that is that when I disconnect from black flush I can see the clean fresh water flowing back out from the vacuum break valve high up in the trailer's interior. If ever I didn't see that, and had reason to think that water would be trapped in the line as a welcoming resort for pathogens, I'd make sure it was fixed before using the fresh water hose to supply it.

As for running the black flush water through an expensive filter... that's a little nutty.

If you know the guy who put that together be a friend and warn him against it.

I saw about 10-15 folks make that suggestion under his post...he wasn't having any of it...to each their own.
