A few weeks ago, I disassembled nine of my valves, rinsed the valve seats, inspected the diaphragms, rinsed the covers and reassembled everything. For about a week or so, everything was just hunky-dory. THEN, our 22 year-old well pump failed and had to be replaced. Upon completion, my pressure tank for domestic water was drained until the water ran clear, as per pump repairmen's instructions. The very next day I noticed that head seepage which I seem to have corrected had started all over again....
