Drinking Water Poll

[Poignard]

See post #8.

If you fill the tanks with a 20% bleach solution, leave 24 hours and pump out via the taps/outlets, you will be missing the bucket of bleach solution by using the tanks instead.

Pretty sure that will bring your water tanks back into safe use.

Isn't bleach supposed to cure Covid?

I'm pretty sure I read that somewhere . . . . .

Only if you use a very strong light and shine it inside you just after you have drunk the bleach.

On the new boat I concluded that given that the Seagull filter is a 99.99% filter and you can literally pour ebola virus in the tanks and drink from the Seagull

Can you link the one you have? The only “seagull filter” I can find is a carbon filter, which is the same as a Brita cartridge. This absorbs chemicals but ebola would be entirely untouched.
As a general rule if there isn’t a pump involved it adds no safety at all since it’s not forcing water through a micron scale membrane or similar which is the only non-chemical way to remove nasties.
Carbon filters can remove heavy metals but offer no guarantee since absorption is haphazard. They do remove limescale and flavours though.

Then there’s the Water2.0 “filter” which doesn’t affect water pressure at all and lasts a year. It does essentially nothing.

I've got this type of cartridge on my galley system Nature Pure Ultra Fine Water Purifier Element
Price has jumped up in the last few years !
Strips out most or possibly all harmful things from water.
Put this type of filter on my heads water tank. Pardon our interruption...
Works well with a foot pump or a simple cheap inline pump. More expensive filters strip out the ecoli bugs, etc but as I fill up with tap water not generally needed.

My parent's old house got its water from rooftop runoff. They had to filter for seagulls and plenty else as well.

I have lived aboard for 40 years. Water is collected from taps and hose where available and from rainwater collection off the deck. We add a sit of bleach to kill nasties. Never had a problem. GRP tanks and they are cleaned every 5 years or so.
On our new vessel we have aluminium tanks so just don't use bleach, carbon filter shoreside water when filling, collect rain water from the deck and have the luxury of a water maker.
I can understand some countries water supply is not good and I would be cautious and use bleach a lot.
I must admit the water maker is nice and takes the edge of water management when waiting for rain.

The filter is the General Ecology 'seagull' so named for the pic on the tap. The kit costs nearly £700 and new filter elements are £80.00.

They are the best.

I drink carbon filtered but the crew drinks bottled water. I tell her I wouldn't:

"The researchers found that, on average, a liter of bottled water included about 240,000 tiny pieces of plastic. About 90% of these plastic fragments were nanoplastics. This total was 10 to 100 times more plastic particles than seen in earlier studies, which mostly focused on larger microplastics." Plastic particles in bottled water

I use the 10" standard filter and buy an expensive carbon filter - but it's nothing like the price of the General Ecology ones.

General Ecology Nature Pure QC2 Purifier with Faucet

This is the same as the Seagull but 30% less as they don't have the stainless canister for the filter element but its the same filter

 

[noelex]

These filters seem incredibly expensive compared to the commercial alternatives; however, we don’t use any filters from our tank to our faucet so perhaps we are out of touch.

On a friend's boat I foolishly rinsed my mouth after doing teeth

I recently learnt that dentists recommend NOT rinsing after "doing teeth". Something about the benefits of absorbing fluoride, I think.
I have been doing it for a few months now.

Here, I see there are other benefits too!

 

[TiggerToo]

On Tigger it is as follows:

Tanks get dosed with Milton at the start of the season. Then rinsed out. Repeat at the end of the summer.

Drinking water (including tea, coffee) comes from a 5lt bottle (we have 4) left over from some cheap supermarket stuff bought 4 years ago and refilled when we are at a marina/harbour. Just to avoid the residual whiff of Milton.

The bottom of the tanks were "hoovered" last year to remove a bit of grit which had accumulated over the past 27 years.

That's interesting.
Most boat tanks are grp. I wonder if the above is aso applicable .

I use Duraphat 5000 toothpaste and, the instructions for it tell you not to rinse after using it, or drink anything for 30 minutses afterwards.

For those with more money than sense?

The process of making the bottles is the cause, I think. They are small plastic blanks which are blown up to size under pressure. That's where the plastic fragments come off the blank and remain inside when the bottle is filled. I can't believe that people actually think that bottled water is healthier than well filtered water.

The toothpaste tube probably says not to swallow though, too much fluoride is not good for you.

swallow: TMI?

(I doubt they state anything like that... you could probably eat the whole thing - over several weeks, and come out of it none the worse; the levels of fluoride in toothpaste is waaaaaay below the toxic limits).

There wasn’t an option for more than one. Basically, we used tank water but occasionally took bottled water on board. A filter improved the taste as we travelled a lot and got water from wherever we were. The answer is to have lots of showers and keep the system well flushed through.

Agreed. We often use bottled water but we have a carbon filter on the galley tap and sometimes use that water for drinking.

 

[lustyd]

Mine says it on the tube, did you actually look?
