Fresh water for head

I converted my Raritans with the conversion kits a while ago. It did big things for eliminating odors for me. I hold 240 gals and there is no stress on weekend supply due to the conversion

Raritan and a company called blue streak make an in-line cleaner system that works really well. I’ve used in on raw water flush toilets in the past with success. I’d love to use it again with my Galley Maid heads, but they don’t do a size for my intake lines.

I found these systems completely eliminate holding tank of odors from waste or raw water, especially when on longer vacations and going longer between pump outs.

I installed a raritan marine elegance toilet and tapped my fresh water system. Works great and eliminated the foul odors.

with a check valve as back up.

Hmmm, sounds like some good @#!* here! I have two Raritan Crown heads too, always used sea water. Never smelled to bad and I always add a shot of holding tank treatment to the head when I leave for the week.
But I like the fresh water thing.. Do they make a 12 volt valve? That looks to be 24volt. What's yours Capt Ralph?

Ok, I wasn't sure. But why can't you just run a water line from your fresh water system direct to the intake on the impellor pump of the head and eliminate any valves at all? when you flush the head the water will flow via the impellor turning? This may be a dumb question.... I don't understand why you need a valve then?

Ok , I see now, and fully understand. Well this project is low on the totem pole for me, because my @#*! don't stink! ...that bad...
I may get to it one day. Thanks C.R.
