Plumbers were of no help, when I turned to an engineer for advice. I discovered that the old fashioned round float valve did a poor job of control. He picked up a paddle valve that cost very little. The metal arm that connects to the paddle has a life of about five years before corroding under water. It unscrews easily. My long torment had ended. Pawan was also a great help with the new toilet installation at the convent. We did treat him to a cup of tea.
