50% of the time of more, it's the septic tether float switch and not the pump that needs to be replaced. The $300 pumps are very, very, durable and can last for 25+ years. A tether float switch is basically a heavy duty extension cord, about 4' long with a float switch built in that is relatively easy to replace, like an extension cord, and cost about 25-dollars at Lowe's.

The tether float switch turns the pump on and off, as needed. Sometimes the float gets stuck/coated up with septic and will no longer float or something, or it gets dried out on top and cracks inside, over the years, and no longer works.
