Re: Stus-List Treating Monel water tanks

[Russ & Melody via CnC-List]

Hey guys,
You guys might need to dig a little deeper, try 
wiki/monel and look to the section "other" and 
the alloy Monel 400, which will be the common tank material.

BTW, it is also the best alloy for kitchen 
sinks... a much harsher application than a water 
tank that gets "shocked" once or twice a year.

It is THE preferred alloy for marine 
applications, far superior than stainless steels 
but a little more expensive so you won't see much 
on production yachts. Lastly, a little reminder 
about our salt water boats sitting in a solution 
of NaCl (sodium & chloride) and the shaft and 
thingies down there last for years and years 
because of an ultra low corrosion rate if Monel is used.

My spring tank routine is a bleach shock (about 
1/2 cup for 15 gallons) to a 1/2 tank then fill 
to top. After a 1 beer soak, I pop the outlet 
hose and drain to bilge. A couple of good rinses 
follow and done for another year. During summer I 
might add a teaspoon of bleach during a fill if I 
remember. We use the tank for drinking and coffee 
water but put it through a Britta filter.
The above will freshen the bilge as a bonus.

Just did some Google-Fu and Monel might not be especially good with chlorine.

Ron,

This looks like a winner!  The tanks are in my 
Hylas.  The Office did not have Monel.

I've read that chlorine reacts with the metal so 
it should be avoided, but that info could be wrong.

Joel,

Here’s what I used for my ‘plastic’ tanks: 
<https://www.fisheriessupply.com/thetford-fresh-water-tank-sanitizer-36662>https://www.fisheriessupply.com/thetford-fresh-water-tank-sanitizer-36662. 
It is supposed to be non-corrosive.

I’m curious how you got Monel tanks.  It is 
corrosion resistant but does corrode.  I have a 
3” ball from a sea valve that has ¼” deep 
pits on the surface where it was exposed to salt water.
