We've never had any trouble with the service from Clearwater Systems Meadville, PA. The knowledge of the guys who come in and set it up is outstanding. We've had the water system for about five years and never had any problem with hard water stains that are common to this area. About a year ago, we had Clearwater add a purifier to the drinking water because the town started adding fluoride and we wanted to get rid of that. Now the water tastes great and we can't detect the presence of chlorine or fluoride. We're very satisfied. The system is doing what Clearwater said it would do. I recommend Clearwater Systems Meadville, PA.
