IP Man (should really change to Hinckley Man)
bet Hinckley wouldn't be impressed with your name change idea if this holding tank idea is your standard thinking

Re: Re-purpose the holding tank for water?

I agree with Valhalla... Germaphobes will never be satisfied

Etch, 2 prime coats and 3 coats of potable water polyurethane .
Replace all plumbing.

Re: Re-purpose the holding tank for water?

Wow great feedback

I think I get the picture now.

Was trying once again to take a shortcut to a solution, just doesn't seem to work on boats now does it?

Looks like a new tank for sure and of course new plumbing and new deck fitting/vents hose.

Thanks to everyone and have a great day!

Re: Re-purpose the holding tank for water?

Water to poop OK. Poop to water not so. Unless you acid /caustic clean then steam clean and flush I wouldn't bother. You'll need to ensure the self passivation of the stainless can recover after this process. It will recover naturally in ambient air.

Re: Re-purpose the holding tank for water?

For those that feel that cleaning the tank and replacing the hoses/fittings are good enough, would you tell your wife/women and guests?

Re: Re-purpose the holding tank for water?

With proper sterilization (etching, strong bleach shocking etc), replacing all hoses and fittings, my guess is you will get away with it. But will you ever really want to have that water in front of you? I don't think I could get past it mentally!

Re: Re-purpose the holding tank for water?

Is drinking water from a clean steel tank any worse than drinking treated sewage? I think San Diego for one, is going that direction.

Once worked with a heavy drinker concerned about his long list of DWI. He cleaned out the windshield wiper fluid reservoir in his truck, and kept it filled with Crown Royal. He cut the hose under the dash that goes from reservoir to wiper squirters, and kept it clipped off with a hemostat when not in use. Voila, an under dash bar! Push the wiper fluid button, and the hose under the dash squirts whiskey in yer drink! No bottle for the man to find (guess he never considered his obvious inebriation). Ah, the deep south...

Re: Re-purpose the holding tank for water?

Ok....assuming and that's a big assumption, that the material used to line the inside if the tank is suitable for potable water, then you do have a course of action to sterilize the inside. This by no means will mean it's "clean" it will just mean whatever is in there will be sterile.

Go to a wine making shop, and buy sodium metabisulfate or potassium metabisulfate.

Empty the tank.

Put in 1 teaspoon of that chemical into the tank per gallon. Then fill up the tank until there is say a couple inches of air left in the top....warning, done breath the fumes, double warning, don't sniff just to see, you'll burn your nostrils and my react rather comically to anyone watching...you have been warned...stay down wind when filling. I am serious!!!!

Let that stand in your tank, and go sailing in a rough sea to splashing it around good. (That's why you left some air, so the water can move around and splash).

While out, let the tank drain but take a sample of what's draining in a clear GLASS jar. If it's steel or aluminum grey in color then the material isn't suitable for potable water, but if it's mostly clear, then hold on to it.

Go back to dock, fill all the way and drain it 3 times to flush out the sulphites. Let that clean water stand in the tank for 3 days.

Let it run from the tap a bit to ensure your tap line is clear of sulphites too...then take another sample in GLASS. Then bring that to your local agricultural extension office and have them do a full work up. That will tell you what impurities are in the water including metals.
If it comes back as clean and safe.

The whole process might take a week, but it will only cost you a few bucks to make sure it's safe...once you've had it tested, no reason to ever think or repeat it used to be a holding tank.

Warped Indeed!!!

Just wondering if we may be shooting ourselves in the foot posting ideas publicly... I mean there's only so many locations to hide stuff on a boat!

Hmm.... My mast comes down right behind a panel above my adult libation mixing station... If I just enlarge the cable run window....

Question: Is it still called an internal halyard if the bitter end is inside the mast?

I can't decide whether I'm ashamed or proud to have fully investigated this particular modification of which you speak... To the point of obtaining a new reservoir and pump assembly....

Questions: 1. Is it possible to remove coring in a non structurally critical location without removing one skin??? 2. Do you know if there are any leaching or structurally detrimental effects of distilled liquor on a large surface area fiberglass tank??? Say... Oh... 1/2" x 3' x 6'?

1. Yes, if you can access it from the side.


2. No, you should be fine. Unless maybe it was some of that "white lightning" they make in your parts, that stuff will strip the paint off a truckbed!

Re: Re-purpose the holding tank for water?

I wouldn't drink out of structural epoxy. It's one thing to use plastic drinking glasses as it's mostly the same thing, but it's another to drink out of a resin designed for structural support. You don't know what was added to the recipe for this or that effect.

Oh... I've tried the white likker stuff, that's an entirely different league and best left for professionals like FlemSCoyle... Like comparing a Sabot regatta to the Vendee...

Hmm... 0.5"x36"x72"=1296 in/cu=21.24L...

Now I see the serious advantages of a new build, and owner input in the very early layup stages...

The whole point is it's the impression of being icky with no basis in fact.

Try this: Would you eat a restauant knowing that someone with VD used the plate and silverware the just put in front of you? I can all but guarantee if you go out to eat at all, it's happened to you.

If you point it out to someone just before eating, a lot of people would hesitate before digging in, even thought the have done it on a regular basis for years.

We aren't talking about flushing the tank with fresh water a couple times and calling it good. The tank would be emptied, scrubbed, bleached, all fittings and hoses replaced...there just isn't a whole lot that will survive that and the stray icky creature that might is no longer being fed it's prefered diet and will quickly die of starvation. From a factual basis, there isn't a problem to speak of.
