In all the years reading about
this topic, some basic "light bulb" idea never got to me until last week. I'd even gone so far as to buy the parts to plumb into the sink drain. I also had gotten into the habit of using the head sink "wand" for the last flush of the head, but ended up dripping in the head, so required more work to clean up.How many of us use plastic bottles, for juice, soda, water??? probably everyone.I filled one up from the galley sink, flushed the head on dry bowl, closed the head inlet, then poured the water into the bowl, and flushed.No additional plumbing, no getting the head wet from extending the head sink wand. No brains for not thinking of this very easy solution 10 years ago.
