[QUOTE=PopBeavers;914215]I always use a filter that is no larger than 2 microns, preferably 1 micron. I recently read that E. Coli is around 2.5 microns. I want to trap that.

Itís never a good idea to mechanically filter bacteria from your water supply. Even though Reverse Osmosis systems can do it effectively because of the ultra filtration they provide, it is still not recommended. The bacteria will accumulate on the walls of mechanical filters and grow. Mechanical filters can fail and without warning or indications. Think of a small tear in the filter material. Suddenly you are bombarded with massive amounts of bacteria. Bacteria needs to be killed with oxidation or uv.

Very soon now I will be buying a larger regulator. It looks like the one on the house except that both ends are hose threads and not pipe threads. It also has a meter.

This is the one I am using now. I also have a gauge to check pressure of the water supply before I hook up anything to the tap and used it to check the cheap regulator and it was only at 39 psi. The shower sucked even with the Oxygenics shower head.
So put this one together and even with it set at same pressure that the cheap one was at the water flow is way better. Set it back to the factory setting of 50 psi and it is better than most homes are now. I put a gauge on the Watts regulator just so I can keep an eye on it.

I thought a little about that. But then I have been backpacking since 1976 and all I can do is use a filter rated to remove Giardia, common in the Sierras. Iodine and halazone are not very practical.

It is possible to purchase water filters impregnated with iodine. But these are normally not used in developed countries.

I do not have room for reverse osmosis. On some occasions I refill the MH up with water from a creek about 12 inches wide and two inches deep, clear water running over gravel, no cows visible upstream. I use my backpacking pump and filter.

In this situation do you have a better choice for drinking creek water than using a 1 micron filter? The filter cartridge is soaked in a chlorine solution when I get home after every trip it is used.

I suppose I could carry more water. But I already have 30 gallons on-board and another 40 gallons in jugs. There is a limit to how much water I can take with me.

When hiking all day while camping I take the water filter with me. Over the course of the day 4 adults on a very long day hike can drink a lot more water than they can carry. Besides that, any water that you carry gets warm. I refill with cold water when I have the opportunity. As long as I can find clear flowing water I can refill the individual water containers any time I cross water. These days crossing water while hiking occurs less often than it used to.

Sure, you do what you have to do. We don’t always have the luxury of purifying our water.

FWIW.

All righty then...but consider this...yea...1 gal = 8 lbs but ALSO consider the weight of the dinged danged filter element once engorged with water? That also adds
a few lbs and even if the water WITH filter weighed...say...6-7 lbs)(okay...
maybe I was overzealous with the other amount)
bouncing up-and-down and most probably not in a very accessible spot. Well...
YOU figure it out and take the chance. I'd inspect the support system for YOUR
on-board filter canister very carefully. ALSO, I WON'T EVEN MENTION the separate weight of the...FILTER C-A-N-N-I-S-T-E-R...which adds back closely to
my overzealous equation, eh?
As for the KY thing...it's water based, grease free, water soluble and I know many
people ...uh...who use it for this very use other than what it is primarily intended for. Go to the KY web site for the specs.. . I just mentioned KY as this might be in more households vs. the silicon grease tho I also use the silicon grease as my primary and when handy. When I use the KY solution I also never have any trouble removing the threaded housing either. Yes then, both are safe in a potable system(and you make a good point here when we start seeing Petroleum jelly, dielectric grease and other bad things for possible ingestion not to mention the
o-ring compromises from these things). Again I stress to also change that o-ring every time with a fresh one before lubing and yea shall never have any problems...if you are brave enough to use the on-board canister at least! Just
watch out for potholes...
