We converted from well to city water earlier in the day of replacing our water softener. We got used to soft water and decided to replace our system. Aqua Systems had a deal on a water softener plus reverse osmosis which we purchased. Our installer was Steve. He called prior to coming out and was on time. He described what all he was going to do. The city water hookup required drilling a two foot wide hole in our garage where the water softener would be installed. The cement to fill the hole was still curing, so Steve decided to install the reverse osmosis system under the kitchen sink first. After the reverse osmosis system was installed, Steve helped us decide the placement of the water softener and the salt tank. We decided the best placement for the water softener tank would be on the fresh cement from the city water hookup. This was on a Friday. Steve volunteered to come back the next day after his son's baseball game and install the water softener. He lived fairly close to us but still this was on his day off. Steve was exceptionally professional. He did a wonderful job of explaining what he was doing, why he was doing it, and the nuances of both the reverse osmosis and the water softener plus the nuances of converting from well to city water. Plus he was friendly and interesting to talk with. Because he came back on his day off to work for another hour or so, I will submit a POH for Aqua Systems. Aqua Systems has been a great company to work with. They also have a drive thru lane for buying salt or bottled water, so you don't have to get out of your car. They load them for you. I have worked with another company for my previous water softener and had tons of problems with their system and sand from the well. Aqua Systems resolved that with filters and one of their water softeners. They are a magnficent company for water treatment issues.
