"I checked the prices and softening capacity of the units being offered at Lowes and Home Depot. I then went on the internet and checked prices from several sources. AffordableWater.us had the best price for a 32,000 grain softener with a demand valve. I called them and spoke with Amber. She was very familiar with softeners and was able to answer all my questions. They even programmed the demand valve after I gave them the water hardness and iron content in this area. The unit was packaged very well and arrived in top condition. I had some questions after I started to install the unit and again called Amber, who was able to answer all my questions. This girl is a big asset to the business. I have had the unit for approximately two months and it works perfectly. Oh yes, I also bought the American made resin, which I would recommend to anyone else purchasing a softener. Buying this unit from AffordableWater.us was a very pleasant experience and I would not hesitate buying any other of their products.
