UV for Water Purification - Does it Work?
Last Updated: 08/29/2012
I would like to know if you sell or even recommend UV light water purification. I have well water and am concerned about it. We donít drink it but use it for everything else, this seems to be a viable alternative to chlorine injection systems.
Most well water is "safe" to drink.
And you can have it checked by the local Health Department ( or get a "bag" for sample to test ).
UV does NOT work if you have well water and bacteria problems ( in my experience ).
The "lens" get's cloudy, and the "lamp" must be changed Annually ( $ 50 - $ 150 ).
We do not sell, use or recommend UV for water purification.
Too many variables and extensive "pre-treatment" is require to "effectively" use UV to "dis-infect" water that is contaminated.

And a "proper" UV ( with lens cleaners, alarms, and sensors to let you know if the UV is actually working ) for a home cost at least $ 1,000.

And the small units for "drinking" water only, can only be used after a Reverse Osmosis system. And annual replacement cost run $ 30 - $ 50.

So, you can not understand why we don't sell them.
I did years ago, and used in my own "water store" and "water vending machines".
And I've seen them installed in residential applications.

If water is contaminated, then chlorine injection, with "contact" tank, and then "de-chlorination" with Carbon Filter Tank, is what we have used and recommend.
This is best properly sized by local water treatment professionals.
