Re: Water purification

Sounds like another excuse to wash in water but drink beer ( grin). On more serious note. being politically incorrect carry bottle water for drinking when ever in area concerned about purity. Next pass on the boat is to put in reverse osmosis when the kitty goes back up. Still use filters on in and out.At least take out particulate matter.

Re: Water purification

i clean the water tanks every year with a heavy dose of chlorine and a brush (very good access to the inside). i add a bit of chlorine to the tank whenever i take on water. i also have a rec vehicle type filter between the water pump and the faucets. cost about $20 at any rv place - also seen them at walmart.

but the admiral still prefers bottled water. so for drinking purposes, there's bottled water stored all over the damned place.

otoh, if you are truly concerned about the purity of your water, there is only one method that is capable of producing it; steam distillation. suprisingly, there are some reasonably priced units available that will make one or two gallons at a time, either on your stovetop or 110 ac. google around if you're interested...

Re: Water purification

The coconut carbon is a necessary evil that causes as many problems as it solves in that its a bit of a bacteria breeding bed

Officially are final microbial filters at work are .2 micron


To be really clean we go 5 micron string filter/ coconut carbon bed/5 micron string filter to remove carbon fines /stuff that does not matter/ ABSOLUTE 5 micron filters/ABSOLUTE.2 micron filters



Of great interest right now is the units like camelbak portable UV unit for camping Treats 80 cycles or 16 gallons with each charge

Re: Water purification

Still think it makes sense as consumables are used up by volume to filter at 5-10microns going in but filter differentially going out. Needs for wash/rinse/cooking and potable water are all different. One can make the case for a variation of a "day tank" like the big boats do for fuel. Personally filter to 5microns. While coastal ( this year) will use bottled water and look into the camping devices. Next year (if funds) allow will add reverse osmosis for potable water. My tanks are GRP with a epoxy liner. Will be rinsed with clean water and baking soda. then rinsed again with just fresh. then periodically bleach shock and rinsed. need to run through all tubing and faucets to get fresh tasting water.

Re: Water purification

Add chlorine to your water. No more than 4mg/l. Filters are good for taking particualte matter out of the water, but that doesn't strain out the little critters. By the way, tap water in the US is treated with cholire.

Re: Water purification

On the hard we're on a well. No Chlorine. Filter system. Lawns/shower/toilets etc. filtered to one degree. all in house faucets UV and fine filtered. Stomach has very low pH. Don't use chlorine in system. Back flush periodically. Haven't got sick yet. Salt pellets cheap. filters more money and less flow as finest goes up. Would like to approximate on the boat.

Re: Water purification

Water from a reverse osmosis watermaker should not need additional treatment, unless it is stored for while. Exposure to air or the container could allow microbes to contaminate the water. Tap water in the US is already treated with chlorine. If you are concerned about microbes in your water, no "filtering" is going to help. Boil the water to kill the microbes or use chlorine. Eight to 16 drops per gallon of houshold bleach will work. There are other bleach products you can use that FDA approved for human consumption.

There are many studies that prove the effacacy of chlorine as a sterlizing agent in water. It has also proven to be safe when used in low dosages. On the other hand, just a few microbes can kill you, and do kill thousands of people every day.

Re: Water purification

Agree a few microbes can kill you but unless you are getting your water from contaminated sources in the US not much of a concern. Infectious diarrhea remains a leading cause of childhood death worldwide but fairly rare here. Well water with clean pipes safe on land. Marina water should be looked at for source and plumbing but unusual to be a problem in US. Would be not as concerned especially if your water is used as sitting water more of a concern. You have billions upon billions of microbes on you and in you as you read this post including many potential pathogens. Still, proper handling of potable water is an issue of all of us on or off the boat. If your water sits by all means add bleach.

Re: Water purification

I think what Knothead is trying to say here is yep, this one.
