Ultra violet filter installation

installing a new UV filter for the drinking water system

We upgraded our drinking water filter system today.

It comes into the house and enters a sediment filter, and then goes to our new UV filter, which is 3 times bigger than the old one.

The attractive stainless steel container is made in Italy by a company called Minox. We found it on Amazon for 170 dollars.

If you don't already have them, consider using copper piping for transporting drinking water from the tank to the tap. They inhibit bacterial growth.

Have you considered Berkey water filters?

Roland-I like that idea. A small section might not be too hard. It makes me wonder how long the effect lasts once the copper gets corroded? Maybe a short section that can be removed easily and cleaned with a wire brush would maiximize the effect.

Gerry-I considered the Berkey filter, but was weary of buying filters so often, and we know our current system works and is safe.

Like most lamps(light bulbs)have a limited life expectancy, you will eventually have to replace the lamp. Ozone can also be used to disinfect water and making a ozone generator with a small high voltage transformer would be easy just time consuming experimenting with different parts.

@Mark: I don't think the copper would corrode that fast as long as it is submerged in water. And as opposed to PEX, copper water pipes are known for not growing a biofilm, so I suspect that even when tarnished it retains its germicidal properties. Studies have shown that at least tarnished brass retains them.
