SHTF Water Filter
I realize there's quite a few videos about this on the inturwebs already. But I saw a couple of flaws in the way they were made that could hinder it's usage in a real emergency situation. Mainly, once you insert the filter into the bucket, you can no longer set the bucket down without possibly snapping the nipple off the filter.
So I've been thinking about this for a while on a way to design this simple filter using off the shelf parts and easily assembled. I'm using food safe buckets with Gamma seal lids. Black lid for the filter bucket, blue lid for the clean water bucket.
I picked up the these parts from my local big box store:
Cut a hole in the bottom of the bucket:
Perfect fit:
Sanded the top of the cap down smooth so to get a good seal with the O-Ring of the filter:
Sealed the bottom piece in with PVC glue and clear silicon:
Put cap down sealed with PVC glue and clear silicon, used a bottle of water to apply pressure while the glue and silicon cured.
Filter fits in perfectly:
I'm currently timing about 5 gallons of water through the filter. It's slow, but it's working. I figure with the filter raised off the bottom, this also creates a "silt sump", a place for silt to settle on the bottom without it interfering with the filter.Rules are written in the stone,

Re: SHTF Water Filter
So, how does it work? Do you sit on it? How much $?

Re: SHTF Water Filter
Or just buy a bunch of brita filters/booble filters, etc..
It would be a good idea if you could make the filter, but in the end you still need to purchase a filter
Also what are these carbon filters really filtering out in terms of chemicals etc.
I would imagine the best filtration setup, as my parents have is, reverse osmosis..Last edited by Svickstc; January 30th, 2012 at 05:22 PM.

The PVC parts I picked up at Lowes, less than $5.00 for both, don't really recall them. The buckets, I do not remember where I got them, but they were around $5 each as well. Glue and Silicon sealer I had laying around.Rules are written in the stone,

Re: SHTF Water Filter
And lets everyone around you know about it. Like I asked, can you sit on it? As in, will it bear an average adult weight and still function?

Re: SHTF Water Filter
I wouldn't see why not. Put the lids on them and you could use it as a seat. If you stack the two buckets up, it would be about the height of a barstool though. The buckets themselves are just 5 gallon buckets with gamma seal lids.
The bucket with the filter sits flat on the lip of the bucket, not on the PVC fitting the filter is attached to. The filter sits a couple inches below the bottom of the lid.Rules are written in the stone,
