The lifespan of a well casing can vary depending on a number of factors, including the type of casing material, the quality of the installation, and the environmental conditions. In Washington state, well casings typically last for 20-30 years. However, there are a number of signs that may indicate that your well casing needs to be replaced, including:
- Corrosion or rust: Well casing can corrode or rust over time, especially if it is made of steel. This can weaken the casing and make it more likely to fail.
