Rated 4.9 out of 5 by 9 reviewers.
Rated 4.0 out of 5.0 by Easy to install! The only reason why this doesn't get a 5 star rating is because while there is documentation on the product in the kit, it doesn't speak to the actual installation of the system. Also, if the top nut holding the crystal sleeve/UV bulb is not tight enough water will seep out and drip directly onto the control board. Oversight in design engineering. Fortunately if you search for the kit on YouTube there is a gentleman that has made all the mistakes, and shows how to prevent them. I purchased the kit because we had colliform in our well water. Our water is now some of the cleanest the lab has ever seen. January 24, 2014
Rated 5.0 out of 5.0 by Recommended for Well Water All I can suggest is to look at your plumbing requirements and make a list of everything you need and might need (just in case items). Installation is very easy. Just take your time putting in the bulb. Use of shark bite fittings and hoses makes it a snap. Extra items are always needed because some modifications are needed to your plumbing but this was installed and running in about an hour. Just like all installations, I installed 2 house filters before the light which makes a difference in the water cleanliness. Maintenance is needed once a year on the light for about 79.00. Great product and it works. December 28, 2014
Rated 5.0 out of 5.0 by This product works great and is a great value. This product must work great because neither my wife or I have had any issues drinking the treated water from the lake. August 22, 2012
Rated 5.0 out of 5.0 by Easy to install and set up. A very simple way to treat water for bad bacteria without affecting it’s taste. Installation using PEX pipe and fittings was fast and simple – no leaks – no alignment problems! June 11, 2013
Rated 5.0 out of 5.0 by Easy to install I read other reviews about leaks around the top o-ring, but assemble it correctly and no problems. My well tested positive for bacteria before, and had it retested. second test came back clean. I also like that you could position it to be a left or right side connections. September 2, 2014
Rated 5.0 out of 5.0 by Work's great! Our well water is safe to drink again and the UV filter even removed the musty smell. August 19, 2014
Rated 5.0 out of 5.0 by Works Great Works excellent. When I bought my house with a private well we had the water tested and there was a small amount of Coliform bacteria. After I installed this unit the water tested 100% clear. December 1, 2013
Rated 5.0 out of 5.0 by Works as aadvertised Instructions could be clearer.... But check YouTube for installation instructions... Works well to keep me in "better than bottle quality water" July 24, 2014
