The lifespan of a well pressure tank can vary depending on factors such as usage and maintenance, but on average, a well pressure tank should be replaced every 10-15 years. Over time, the tank's bladder or diaphragm may deteriorate, causing the tank to lose its ability to hold pressure or to develop leaks.
It's important to note that regular maintenance can help extend the lifespan of your well pressure tank. This includes regularly checking the tank's air pressure and performing routine maintenance on the well pump.
If you notice any signs of damage or wear on your well pressure tank, such as leaks or corrosion, it's important to have it inspected by a professional. Additionally, if you experience any changes in your water pressure or notice air or water coming from the pressure relief valve, it may be a sign that your pressure tank needs to be replaced.
It's important to have your well pressure tank inspected and maintained regularly and to replace it when necessary to ensure a reliable and safe water supply.
