Can this be used as a gravity type filter or does there have be pressure to make the water flow through the filter?

It makes a great gravity filter--I purchased some surgical tubing (no memory coils) that attach to each end of the filter. The "uphill" tube inserts into the water source (bucket or bear canister), when with some sucking, the water will siphon up and over the side, and down through the filter, into the downhill tube and your water bottle. I do not use the sawyer bottle, except for storage. Once the first container is filled, others are quickly put in it's place until the source is out of water, and the cycle repeates. I love the backflow syringe for instant cleaning--BEST feature of the whole device!

These are actually used as gravity filters, but to be honest I would recommend the point zero 2 (.02) microbe filter for that, because it is larger and designed for gravity(as far as what is included). Anyways, yes it can work, but if you are referring to gravity as the pressure in a 5 gallon+ bucket, it would need to be at least 1/3 full and generally pre-filtered of particles. I would expect great results from this for you

The short answer is YES it will work as a gravity filter but using pressure or squeezing will assist you in filtering much quicker. Take a look at this video and you'll see the Sawyer Mini Filter in action as a gravity filter. I hope this helps. https://www.youtube.com/watch?v=GXQ2zBhiUlI

I believe it says in the instructions you need to move it closer to the filter to get a water flow / movement but I may be wrong. If that doesn't work use a flat head open and clean if it was a used one.

This unit should work on a gravity system as it shouldn't need a minimum flow like a tankless water heater does.

You can definitely use this as a gravity drip filter. I went on a 3 day backpacking trip and I had it attached to a bladder and I would fill my bladder with water, pull off the end where I would suck the water from and very quickly use it to fill up my fellow hikers bladders that didn't have this filter. It was great for filling the pots for cooking. It is much faster then the older pump filters. I would highly recommend this system.

It's kinda "compressable", so has plastic panels like you see on the sides. Probably best if you need a more flat filter rather than a cone type.

You might want to check the pump for any kind of blockage,it does not come rushing our with any kind of pressure.I thought there would be more pressure coming out after I installed mine as compared to other filters I have had in the past...that is not the case with this filter/pump set up.

When you have it on the filter setting yes .If the filter itself is properly set up, it is not greatly diminished when filtering. When the filter is not being used,it should be normal pressure.

This fuel water separator installs from the tank to the engine or in your case the outboard. it needs the suction of the fuel pump to draw fuel through it. gravity fed fuel would not be able to pass through the filter. Hope this answers your question C. Blue.

Some water flows through, i bought a cap to stop water from going through no problems filter works great.

Two questions: what kind of filter are you using; and are you sure the selector is switched to allow water to flow through?

It would depend on which filter you put inside it. I only use a sediment filter in this; so as not to disrupt pressure. I have a second filter in my fridge that I use to filter out the stuff like arsenic

Yes, this is a filter, it has to be oriented the same way it is in the photo. It draws water up from the bottom and pushes it through the filter media and then out through the top of the filter where it forms a sort of waterfall.

Yes. Should go thru a pressure regulator, or fill slowly, or filter will not get a chance to do its job. But it did a good job of filtering .

I don't see any reason that would prvent it from working in the vertical position as long as you follow the inlet/outlet flow positions. it's the directional flow of the water and not gravity that gets the job done.

I used 1 1/4" tube with the included pump and it has large flow. The filter doesn't hinder flow much if kept level with water. Extreme elevation will slow the flow. (Over 10 feet) check for blocks. Check the pump by itself

Not really. I think what you want is a particulate filter or reverse osmosis for that issue.

I an not an expert, but I would say that any size centrifugal pump would work, but only so much flow will pass through the filter . A positive displacement pump may build up too much pressure to be effective
