???? I can't see how that would work in any marine sanitation system. Back when I was a young pup in a design office drawing piping schematics for passenger vessels I used to put these in on every sanitary piping plan because they were on the plans they gave me as a "go-by". These were large vessels by yacht standards, generally with ordinary jet flush toilets like you would find in an office building. I can't see any reason why it wouldn't work in a fresh water flushing system. Even if you had a large flushing tank, you might want to be able to replenish it from the main tank; especially if you were running an RO system into it. Here's how it would look: http://home.maine.rr.com/rlma/Flush.jpg On the large vessels with engineers monitoring everything, the float switch was just a manual valve and the flush tank large enough for about a day's use. My sink drain connection to the head intake is just a variation of this. If I simply added a 2 -3 gallon tank into the line, which I have some minimally useful space to do, I could easily set the system up for several unattended FW flushes. This is something I might want to do if I planned to visit some place like St. Johns, Newfoundland where the water coming into the head might well be dirtier than the water flushing out of it ![]() -- Roger Long |
