"Michael came out and gave me a detailed presentation of their product. Corey installed it days later and itâ s working extremely well. Very happy with this soft water system and warranty. Would recommend Aquias Water Treatment company to anyone seeking professionalism, courtesy, and a system that performs as expected."

"My water softener (which I inherited from my grandmother) was stuck in an endless purge cycle, so I called the man who installed it, but he was no longer in business. I looked on Angie's list for another merchant. I found AOK and the reviews looked good, I liked that it was a family-owned company, and the prices that people paid were in my feasible range. I made the appointment to have my softener looked at, and Kevin showed up a few minutes early. We reviewed my options, and we determined that my system, which was not new when I inherited it a few years ago, was too old to fix for a price that made sense. Replacing the entire system cost only $250 more than repairing, so I went for it. I was at work, but my roommate was home when Kevin returned to make the repair. He said the water would be out for a couple of hours, but it was less time than that. The water has been even softer than it was before ever since. Very happy with my purchase! The grade of B for price merely means that I had not intended to pay that much; it is not meant as a criticism of AOK's prices. The grade of B for Quality reflects minor complaints, like leaving the soil turned over and piled up around the softener, leaving an empty sports drink bottle, leaving the cord from the old system balled up on the ground, etc. They were really minor annoyances; I would use AOK again in a heartbeat."

"New drinking water Reverse Osmosis and whole house Water Softener. Water Test Results 1 month later: Pre Water Softener is 0 = SOFT In house after Water Softener 15 = HARD. Major difference. After a shower my hair used to be rough, hard and hard to brush out. Hairs on my legs and arms actually broke off. After installation my hair is soft and after 2 weeks my hair on my arms and legs are growing back. Ans due to the under sink 10 Stage Reverse Osmosis my separate sink drinking water Faucet and refrigerator water tast great the ice cubes are clear and now I save a lot of money not buying drinking water. And the owner Erik is the best! Very Professional, knowledgeable and helpful and answerd all my concerns and questions."

"They were on time and the service was good. I have been using them for about 3-4 years. They installed my water softener system and my reverse osmosis system. I am on a plan to replenish the salt in my water softener and they do a good job. If I had any problem with plumbing, they are responsive I would recommend them to anybody."
