"We got a quote from leaf home water solutions, Frank was our sales person, he was very nice and personable. We decided to buy the system. We have well water. We had hard water. We were sold only what we needed! Nothing else! Our installer was Andy and he was also very nice and cared about the work he was doing! He made sure everything was level and did a wonderful job! Thank you guys! We are very happy and our water tastes good."
