Thanks

Try ordinary vinegar.

Yes, it's true. Distilled white vinegar will dissolve and then prevent
future buildup of sea water minerals in pumps and hoses...not only in
sanitations systems, but in all raw water intake lines.

Use ONLY distilled white vinegar...it's a lot more acetic than cider or
wine vinegars. Plus, it's distilled from alcohol...cider and wine
vinegars are distilled from fruit juice, which can leave a sticky residue.

If you have a serious buildup, you may want to use a 12% solutions of
muriatic acid to clean it out...white vinegar will work, but it may
require several applications, whereas muriatic acid will work a lot faster.

Once you've cleaned out the system, a cupful--two at the most if the
lines are longer than they should be--once a week, flushed ALL the way
through the system (do NOT leave it sitting in the bowl!) once a week
will prevent it.

Distilled white vinegar is available in any supermarket. If it's not on
the shelf with cider vinegar, it'll be in the cleaning supplies
aisle...'cuz although distilled white vinegar has very limited
application in foods, its primarily a cleaner.

You might want to google "white vinegar" to see all the cleaning jobs it
can do.

It will evaporate, leaving no residue on things like windows and
mirrors, and it eats soap scum on shower walls. It's also cheap.
The muratic acid mentioned will remove rust stains from plumbing
fixtures, and vinegar won't. However hydrochloric [muratic] acid fumes
are highly corrosive.

Peggie,
Won't the hydrochloric acid eat the porcelain bowl?

Nope. Won't eat rubber either. In fact, owners and pros have used it for
decades to clean sea water minerals out of raw water intake hoses and
raw water engine cooling systems. The instructions for
cleaning/descaling) the Lectra/San electrode pack also call for a 12%
solution of muriatic (hydochloric) acid, flushed into the unit through
the toilet.

SS fittings in the sanitation system plumbing??? Not a good choice,
'cuz urine will corrode 'em. At least one trawler mfr who puts all
fittings on the top of the tank, with a pickup tube inside the tank on
the discharge (a great idea) used stainless fittings and pickup tubes--a
VERY bad idea, 'cuz the tubes are corroding, even falling off in pieces
inside the tank, in just a few years.

Peggy,

Pardon the pun, but you really know your ****!

hahahahaaa!!!

Couldn't resist!

Peggie,
The dilemma is the Lloyds certification for thru hull fittings, which call
for fire proof valves against your years of experience. My solution will be
plastic valves at the plastic holding tanks in deference to your experience
and 316L valves at the hull. This solution should satisfy both. Thanks for
the Muriatic tip. It should have been obvious, but I did not consider scale
build up as an issue.

If you must use metal for your thru-hulls, use bronze. It's a lot more
resistant to urine than SS...almost bullet proof. In fact, the best
high-end manual marine toilets--Blake, W-C Skipper, Groco K etc--are
bronze "thrones."

Umm.....where in the grocery store do you suppose you might find acetic
acid?

Uhmmm...right *next* to the vinegar maybe?

Keith Hughes

Yes, acetic acid is white vinegar, but the stores only carry 5%
strength which seems to do little or nothing.
