I have an old well which we have used for years. Recently we built a new cabin on our land and my significant other demanded I get the water tested prior to allowing us to use the water from the well. So I got the water tested and the results came back that is tested positive for coliform bacteria. I have been doing some research on how to decontaminate the well, but I'm not confident any of these will work for sure.
Now I have an extra Reverse Osmosis unit and was thinking maybe I could use this. My problem is trying to figure out 1) if this will work, 2) how to get it set up? If it will work, then I just need to figure out how to get the water from the well to the cabin with enough pressure for the RO unit to work properly...it needs at least 40 psi, but works better at 75-80 psi.
Any help or comments would be appreciated.

RO filters are supposed to remove coliform bacteria. You will need a huge system if you want to filter 100% of the house water
What's your question about setting it up? Water in, water out and a waste line. Most of the drinking water systems I have seen also have a small pressure vessel to store a couple gallons ready for use

What do you mean I would need a huge system? I have a 100 gal/day system, I don't think I would need more than 5 gallons a day...not even that much in reality.
I really only want to use this for drinking/cooking water while we are at the cabin. We use a lot of water, especially when it is hot for things like kool aid, lemonaide, etc. Then not to mention for coffee.

I hadn't even heard of those filters...if they weren't so expensive it would be something to look at.

You can get a pair of the filter elements for $100 on eBay.

Is it just me, but doesn't that seem to be quite expensive? My RO system cost me less than that.

The filters are advertised for 3000 gallons each useful life. If you and the SO use 3 gallons a day that's 2000 days, almost 5.5 years of daily use from a pair of filters.
How much water will that RO system filter without a pump to drive it?

I have pumps to drive the RO System; but those filters are pretty interesting, I'll give you that.

Anyone have any experience with the Berkey Black Element Filters? They sound pretty interesting. My question is if they can be used intermittently, or if once exposed to water if they must be kept moist?

Thanks Rob_O; I sent the manufacturer an e-mail last night asking about this and received a response this morning letting me know they can be used intermittently, but I appreciate you response.
