"We are loving our new filter system. Our water smelled terrible of sulfur and had iron bacteria. As soon as the system was hooked up and water had circulated, the smell was gone. Still making adjustments to the settings. We went through 5 gallons of solution in 3 weeks. Yikes. Called customer service who walked me through setting changes. Thank you very much."

"It was a very easy installation, but it was very helpful to have access to the tech support via telephone. They were always quick and knowledgeable. There were a couple of details in the manual and video that didn't match the actual system . . . 1) bypass valve and 2) a sensor. so it was great to have confirmation from the experts. Also, the bubble/fizz test with the H2O2 never actually got to 5 seconds of fizz. It was either no fizz or ~25 seconds of fizz. The original setting recommendation was 20s 50% and I went through 10 gallons of H2O2 in a couple of days. Over time I dialed it in. I also had to rush order another 10 gallons of H2O2."

"The pros who installed it said the setup was pretty reasonable. It booted right up, and we have *much* better water now. Metallic taste is gone, and the slight sulfuric aroma, especially from the hot water, is now also gone. I'd recommend the system."

"In service two weeks, so far, so good. We're looking for testing products that are a bit more re accurate than the "look for bubbles" technique. That's equivalent to getting a weather report by sticking your head out the window."

"John was very helpful getting everything working . Seems like peroxide feeder wasn't working sent out new duckbill seems like it's working now. I'll give you update thanks."

"I had one of your systems installed on the small cottage that I have on the same property as my home and it worked great. I ordered a second system (my setup required it) and it has worked fantastic in both places. It took me over a year to find you and I wish that I had found you sooner as al of the other systems told me that they could not help me after looking at my lab results.The customer service was so very helpful both before I purchased your system and after. Thank you for finally giving me potable water in my home!!!!!"

"We recently purchased and installed a whole water softener and reverse osmosis system. The whole water system appears to be working very well however, the water still looks great in color after a week and a half After being installed. The reverse osmosis is still not working properly. We have been working with staff from US water systems, but the problem is still ongoing."
