Professional, accommodating and fast!
Jon knew a lot about the water filter and had answers to my questions.
The periodic delivery by Reynolds Water Conditioning of potassium chloride to the water-softener bin in our Ann Arbor house has been superb. Reynolds always phones ahead to make sure that we are expecting a delivery, and their delivery person is always polite and most helpful. Nothing but praise for their service.
Hopefully he has successfully diagnosed problem. He listened and worked on an explanation and correction.
