[C320-list] Head Fresh Water Plumb

[wflowe3 at aim.com]

 I have several pictures of my dedicated head-water tank on the website. The tank is in the aft lazerette with the steering quadrant. Once you log into the website, go to gallery and you should be able to find the photos by searching for "water tank".  By my calculations, the tank holds about 15 gallons of water. The holding tank holds 22 gal. I use the tank capacity as a gauge for pump out. Once the 15 gallons of fresh water from the fresh water tank has found its way to the holding tank (combined with the human contributions that got it there) I pump out.

Don,

Hopefully, this information is helpful...

1.  I just use my shower head to flush the head with FW.  I didn't want to 
possibly cross-connect my FW supply with the toilet bowl.

2.  If you do plumb from a FW tank to the head flush, I would encourage you to 
install a stand alone FW tank just for that purpose.  

3.  I tried installing a 3rd 20 gal. FW tank in the aft hull space next to the 
diesel fuel tank per one of the well written articles on our C320IA website.  
Bought the Todd Tank and all of the parts, unfortunately for my hull, the tank 
would not fit in this space between the stern and the rudder tube.  Real bummer.  
The tank was too big by about an inch or so.  No way to cut down the rotomolded 
tank.  Smaller sized Todd PE tanks that would fit, are too small to bother with 
glassing in an installation tray into the hull.  This seems like a good location 
for a small (10 gal or so PE FW tank dedicated to flushing the toilet if you 
think it is worth the effort.

4.  Not sure the PEX at Lowe's is the same dia. as the Whale tubing.  I remember 
something about Metric vs. English sizes.  I purchased my PEX tubing and Whale 
connectors for my washdown pump installation from our local marine store.  It 
all worked great, but I probably paid a "marine store premium."

5.  I believe there is some information on our C320IA website about installing a 
FW tank dedicated to the toilet.

This type of stuff make great winter projects.  That is what I intended to do 
last winter with my aborted "it would not fit my particular C320 MK II hull" 3rd 
FW tank installtion project.  

I have a 20 gal Todd PE tank and the fit kit tank adapters that I have been 
trying to sell at our local Seattle-based marine exchange.  Perhaps I will 
advertise them for 1/2 price on our C320IA website.

Good luck.

option of using saltwater when cruising. I assume I will have to tie into the 
fresh water line under the sink. I expect I will also have to turn on the water 
pump for use. Is this what is done or am I missing something?  I think the Whale 
fittings are the same as some PEX fittings I have seen at Lowes but haven't 
looked closely yet. Anybody else done this and what did you use?
