It depends on the pump and how often it is used. A submersible well pump can last anywhere from 5-10 years, but it's important to keep an eye on the pump's oil level so that it doesn't run out of oil and seize up. If you do experience a problem with your well pump, be sure to call a professional rather than trying to fix it yourself. Pump repairs can be tricky, so it's best to leave them to the experts.

It depends on a variety of factors, including the make and model of the pump, how often it's used, the water pressure and flow rate, and the quality of the water. In general, you can expect a submersible well pump to last for around 7-10 years. If your pump is older than that and needs to be replaced, it's a good idea to have it inspected by a professional to ensure that there are no underlying issues that could cause problems down the road.
