Warning signs include sediment or sand appearing in your water, unexplained drops in water pressure, unusual taste or odor in your water, and visible corrosion or damage to the visible portion of your casing. If your well water quality suddenly changes or you notice water pooling near your well head after rain, these could indicate casing issues requiring professional assessment.
The appropriate approach depends on your specific situation. A professional well contractor can evaluate the extent of damage and recommend whether partial or complete replacement would be more effective and economical for your particular well system.
Minor casing repair or extension typically takes one to four hours. Partial casing replacement can take four to eight hours, and a full casing replacement for a deep well could take up to one to two days.
The timeline for well casing replacement varies based on several factors including well depth, accessibility, and local conditions. Your well contractor can provide a project timeline specific to your situation after assessing your well system.
PVC casings last 20 to 30 years in appropriate conditions. Steel casings, including galvanized and stainless varieties, provide 20 to 35 years of service, though this can vary based on water chemistry and environmental factors. With proper maintenance and favorable conditions, PVC casings can last up to 50 years.
