Nothing terribly exciting or new here, but just thought I'd share how I do it with you. I used this rig last year in the BW with no issues, I made this one for my sister. It's an easy project that gets you a lot of water relatively easily. There is a parts list below the video on the youtube page if you're interested.

Simple DIY Water Filter Bag

You did a great and professional job with this filter bag, will be revisiting this thread if my Katadyn goes down.

Thank you very much.

Good job on the video, easy to follow. The bulkhead fittings look like an improvement over the hardware store fittings and the links to US plastic should make them easy to order.

Thanks Wingnut.

I built two of these exact same gravity filters this past summer before I saw this link. Mine has a few points of difference:
- I placed the outflow valve 1" from the bottom of bucket and right under the logo in the front. Allows you to get more water out of the bucket.
- For the outflow valve, I used one with an auto shutoff. In other words water won't flow unless the tubing is locked in place. Don't have to leave filter or anything else attached when filling bucket.
- I used some nylon washers that I picked up at a home improvement store on the inside and out side of the valve and siliconed them in place when assembling. Also picked up nylon nut for valve at home improvement center.
- I used a Sawyer Mini filter. For under $15 I carry a back up as well. I found that the pre filter really slowed down the flow. It was much easier to backflush the filter once or twice a day.
- From the bucket I ran a 6" piece of tubing to the filter then a 38" piece to the bottle or pot that I am filling with a shutoff valve on the end.
- My system is assembled in this order from bucket to end: bucket with outflow valve, 90° male connector, 6" tube, filter, 38" tube, shutoff valve. I actually used a couple of in-line connectors and have a couple of different lengths of the tubing after the filter to accommodate varying heights of bucket placement.

Here is my list of parts:
Collapsible Bucket
Valve w/Self Close
90° Connector
In-Line Connector Male
In-Line Connector Female
Tubing
Shutoff Valve
Sawyer Mini Filter Kit

Very nice, I like the auto shutoff at the bucket! Thanks for sharing.
