Diagnosing & Repairing Residential POE Systems: Part II

In the May 2007 issue, we primarily examined how automatic water softeners operate and discussed many of the potential solutions to operational challenges. Observation, documentation and testing were noted as the most important starting points.

In this issue, we will further discuss specific problem areas and how to overcome them systematically.

We will continue where we left off, with brine concentration and contact issues.
