Are these pouches designed to also act as a pressure clean out for the filter - to replace the syringe?

Sawyer recommends using the syringe. I have not tried what you are asking but I don't think the bag can create that much pressure.
581476
I have not done this and would suggest you might not want to... Three things to think about: 1) Syringe gives lots of pressure - instructions note the filter can take a lot of pressure - and weight next to nothing (why not carry it), 2) Bags are "squeezable" but that is only to the point of pushing water through filter...I would be concerned about rupturing a seam, 3) I like to keep the bags on one end of the filter...to keep things clean.I f you are concerned about clogging on the trail take two...not likely you'll clog both up on the same trip.

No...need syringe to apply high pressure. I put the syringe against my chest and use both hands to pull the unit back with all my mite. Works great. 3 of us camped on only water source for a week, which was a stagnant beaver pond. Water smelled bad but no one got sick.

I think my answer would be close to what R.Pe noted,good information there.What I would say is that unless you filter from some sketchy sources a lot the Sawyer filter won't need back washing in the field.When you get home you can backwash your filter.I hike with 3 guys several times a year and we all carry the Sawyer,we will bring one syringe between us but on four trips we have been on nobody had to backwash-that being said chose your water sources wisely.

Sawyer recommends using the syringe. Besides the bags screw on to the wrong end to be used to flush the filter.

No. The bags are strick for water storage and to eliminate you from ducking too hard. You can squeeze the bags a bit to push water through. Some folks I know, never use it as a straw...just fill other containers from the bags. The syringe is to reverse flow and clean.

I can't answer that definitively as I have never tried 'filterless', but it may work. The rubber holder keeps the tube in place until you crank the handle almost the whole way. At that point it releases so as not to damage the end of the cigarette. It may suit your purpose just fine but I cannot answer that for sure...

Yes. Just trim the pack plastic strip to fit around the filter. Very easy to do.

I am no expert but I think what you are asking is about the outer plastic disk that these slide into. The outer disk can be reused with these filters. Hope this helps!

Yes, that's what I use mine for. I use the BD Allergy Syringe (28G x 1/2" 1 ml) and it's a perfect fit without using any spacers.

Yes, size, but a syringe would work a whole lot better. They would probably make a mess. these are more for liquids.

Sure - though you likely wouldn't need/want the plunger/filter - which is easily removed as it screws apart. :)

Yes, the filters are used to filter out debris, particles, food, pet hair, etc from getting into the pump. It doesn't not change the "water" other than filtering it.

While I don't know that this will be helpful to you given the time since you asked the question, for the edification of others I'll throw this out there. All sawyer filters are designed to be back flushed to clean them out. That is what the syringe that comes with the system is for. Fill it with water, place it on the out of the filter, and force water through it. You may have to do it a couple times.

There is a connector that fits the threads on the pump and is barbed on the other end. You just push the filter onto the barbed connector

They don't always work immediately. The scotch brite tip works, allow the filter to dry entirely and then when resubmerged in water allow a day for it to become saturated with water all the way through. I promise they work and I personally believe a slower filter is not such a bad thing. Allowing some way for the system to vent is critical as well, get creative. Messing with that ceramic filter a lil bit is a lot less effort than carrying cases of water. The Dude..... I'll gladly take those off your hands.

Yes it will work as a gravity filter. It works really well too. It will drain a 3L bladder in just a few minutes. I added anothe quick release near the bite valve so I could use it either way.

Not exactly, I have to trim one of the end of the filter, for it to go into the filter housing/cavity.

If the filter has a hose that you can cut and place this sterilizer in line it will work.

No. This type is for external use. I use mine on the outflow hose of my cannister filter.

sure, but will get stuck in your filter. You will have to clean the filter quickly

The pouches are used to collect the untreated water (place into a pond or ditch or hole or stream). Should be cleaned later with a bleach solution on a regular basis.
