Replace 1.5 HP well pump 3w 230V set at ~550' and to be determined. Replace 540' of well pipe with schedule 120. Inspect pipe and wire when the existing pump is extracted and advise. Based on the field notes the down well pipe is a combination of galvanized pipe and PVC and set at 650' +/-. If it is schedule 80 PVC married to galvanized pipe there is a strong possibility that the PVC pipe and couplings have deteriorated with age and are leaking water back into the well. In an ideal world all of the pipe should be galvanized at this depth and PVC should be limited to a pump set depth of ~500'. Schedule 80 PVC is no longer an industry standard for setting of well pumps and it is replaced with schedule 120. Given the age of the pump, and with an average pump life expectancy of 12 to 15 years we may find that the well pump is not working as intended and requires replacement. This cannot be determined until the well pipe is raised above the wellhead and turned on. In any event, if th
