Lectra San
I too am in the process of installing a Lectra San and Vaccuflush.
All the discussion about salt tanks leads to to think that these are fresh
water applications. I am in the PNW, so can I not just hook up pressurized
sea water to the toilet? It seems that the Vaccuflush is designed for fresh
water, but is there a inherent problem in feeding it with seawater?
Any one using raw water in this set up?

I have been using a vacuflush head for several years with a raw water
flush. I also have a lectra-san with a four gallon salt tank (with pump)
that is also hooked up to raw sea water. The only problem I see is that
There is a scum in the salt tank caused by the creepy-crawlees
die-ing when they hit the brine in the tank. I talked to Vic Wilman at
Reritan about that and he said there was no reason it wouldn't work, and it
will use marginally less salt. The vacuflush works fine, except that I get
a build-up of salt in the plumbing. I change out the lines to the vacuum
tank about every three years. Not a big deal I can get to everything
without being a three armed midget. (Apologies to any three armed midgets
out there.) I am happy with the system so far and my freshwater lasts a
long time when I am cruising.

Since toilets--including the VacuFlush--designed to use pressurized
flush water have no intake pump, using sea water would require
installing a flush water tank and water pump to provide pressurized
water, or removing the water valve from the toilet and replacing it with
an intake pump to pull sea water to it--which would also require wiring
it...which in turn would mean replacing the flush pedal--which needs no
power--with with a button. If want to flush with sea water, why spend
$2000--$4000 for a VacuFlush installed when you can buy any one of a
dozen electric toilets designed to use sea water for around $500?
It seems that the Vaccuflush is
designed for fresh water, but is there a inherent problem in feeding it
with seawater?
In addition to all of the above, flushing with sea water defeats one of
the main advantages to toilets designed to use pressurized fresh water:
the elimination of odors caused by stagnant sea water trapped in the
head intake and channel in the rim of the bowl.
