Multi Day Water System - 06/23/14 10:46 AM

Hey guys I'm new to backpacking. I've done my homework and have came up with a water system:

Platypus Big Zip 3L... 5 oz
Nalgene Ultralight 1L(an oxymoron, I know)... 3oz
Sawyer Mini Filter, syringe, and 16 Fl ounce bag... 2 oz

Summary, 10 oz, 4L, lasts 100,000 gallons (I think)

My plan is to go a water source, and filter right then and there, and then move. I would primarily drink from the platy, the Nalgene would be mostly for washing up, cooking, ect.

I have three questions:

1. Would the big zip and nalgene thread with the sawyer properly?

2. Should I carry another nalgene UL?

3. Have you had any experience with platys malfunctioning in the field? Is this a concern?

Thanks guys! Any input is appreciated!

I haven't got that much personal experience with the Platypus though I use their 4.0 gravityworks. I have yet to have any issues with it nor have those I have come across. Heck, this past weekend there were 3 other groups running the same set-up. I'm the only one that was using the carbon-filter (turns out there is no taste in the water here to filter so I'm leaving it at home next time).

I have, however, heard a few issues both on the forums and in the field of the sawyer system blocking easily and not wanting to back-flush or clear. The platypus as long as you follow the directions works great.

(start the flow, let about 1/4 liter or so come in, reverse it to purge the system of air, then it flows quickly. When you are done filtering back-flow about 1/4 liter to clear it out. That's it.)

I was referring to platypus bladders, not filters, but thanks anyway. I'm not sure about the gravity works, it seems a little bulky.

Do you know if the squeeze is anymore reliable than the mini?

I lack any personal experience in the Sawyer to say but I like the idea of the smaller one (Squeeze?) that can go inline on a hydration pack. Maybe someone with more experience will chime in.

On two occasions, I have had Platypus Big Zip containers develop leaks, usually along one of the folds. Interestingly, I have never had a standard Platy 1 or 2 liter water "bottle" develop a leak even with hard use. The leaky BZ's were circa 2005 and the issue may well be resolved now but I know that once upon a time they did develop leaks, easily.

For a simple water bottle I see no reason to carry a Nalgene when a recycled pop bottle is equally sturdy and a third the weight.

I use a Sawyer Squeeze, the larger version of the mini. I have had no problems with it in two years of use. And, that is with the original, failure-prone, bags.

I've never tried but I have heard that Platy threads leak with Sawyer equipment. Evernew bags do mate with Sawyer filters, or so I've been told.

Do you know of any bladders that would be compatible with the sawyers?
