    6 Stage RO UV Water Sterilizer

    I purchased this filtration system for our well water supply. The water has always tested clean so I didn't need a whole house filter but we've got a lot of new construction going on in our neighborhood, and we're surrounded by farmland where some of the owners spray indiscriminately, so we decided to be proactive. This is probably one of best DIY kits I've ever worked with (and I do a lot of DIY projects). I used both the instruction manual and the installation video and never ran into any confusion or glitches (both guides are excellent). Admittedly it took me about four hours but I was intentionally working slowly to avoid catastrophic leaks, and I was working in a pretty tight space under the sink. I did have one leak at startup that was my error: the filter canisters should look like the illustration when installed (label facing front). I didn't tighten the GAC filter completely and yes, of course, I had a leak. I caught it quickly so no harm done, and it was the only leak I experienced. Additionally, I don't think I've ever purchased any kit that was packaged as well as this product was, and none of the parts were missing. I was pleasantly surprised.

    Got unit on time - instructions good & detailed - installation takes some time - unit works like I expected.

    Great service, good product

    I’ve been a customer for a couple of years now and i’m very satisfied with the products and the customer service. I had my furnace quit while away on vacation and had the filter bodies break when they froze. The leak stopper worked as it was supposed to and kept the water from running out when the water thawed. I had new filter bodies shipped out with help from customer service and was back to filtered water in five days. Free shipping and a good price for the filters is a plus. The system works as advertised and we would not hesitate to buy another should the need arise.
