I want to use some sort of gravity fed filtration system when in camp for my water. I need a light wt. system. My thought is: hang a platypus 3L somehow, tube goes to Sweetwater Silt stopper, then thru tube to Seychelle In-line Filter, then thru tube to another platypus 3L. Any thoughts??

Sounds like a good plan.

Another possibility - Have you seen the Hiker's Friend style of gravity systems? You could use a normal size filter (would they last longer than the in-line?) and substitute some panty hose for the silt stopper (save cost/weight). Then run it to the Platy as you describe. Just a thought - might be cheaper and weigh less.

This isn't from personal experience (I use iodine, or boil) but I've only heard of 2 problems with a homemade gravity system:
1) if you get a filter made for a pressurized system you'll be waiting forever for your water
2) sometimes filling the prefilter bag can be a pain, especially from a shallow water source.

You can use a dip cup to fill the waterbag or platy. I hadn't thought about the pressurized filter - that's a good point.

This system works well. You can plumb the filter easily into a Platypus and leave the bag at home.

I carry the bag as well because it's easier to collect water from shallow sources. Very handy for cleaning up, as well.

hey jeff! for a guy who's never really hiked out in the woods and has this really lame web site, you sure know your gear! HOW do you do it!? ( :biggrin: sorry... the target was there.... i had to shoot, even if it was a 'friendly'...)

(for those who don't understand why that was funny, this is military humor... he knows i was just kidding, and to what i was referring...)

i love you man... (but you can't have my beer.)

HOW do you do it!?

Just pretending, that's all.

(And I don't need your beer - I already recon'd your scotch...)

(thanks for taking it in the spirit in which it was intended)

Dang... so that's what happened to it...

Thanks for the info. I think the Amigo from ULA will fit the bill.

Just put the Seychelle in line with a bag and add a positive on -off From Camelback in front of the bite valve...pull off the bite valve...hang the bag up side down...open the on-off...put what ever under the set up ..done...I have used this system for 2 + years...

BONUS... you also have a scoop and go filtration system....

EXTRA BONUS... if you keep the on-off closed, you will never have the "puddle leak" ( especially bad luck if it is all over someones bag on a 35 degree evening) in a crowded shelter when someone sits or kneels on the bite valve of an unattended water bladder....NOTE....this happens a lot...it is cheap insurance...and it prevents unintentional water loss when water is in short supply.

Platipuses work well in this arrangement...get the stand up model and use a hole punch in the excess bottom material corners and then you can add a handle of 2mm cord....easy to carry...easy to hang.
