What is the average life expectancy of a well pump?
Thursday, January 16, 2020
You can expect a residential well pump with moderate usage to last about 10 to 16 years, with an average of 12 years. The well itself has a 20 to 50 year life expectancy, with an average of 35 years. Here are several factors that will affect the lifespan of a well pump:
• How long pump runs throughout each day - This is also called the “duty cycle” and, obviously, pumps that are used more have a shorter life. But the number of times the well turns on and off each day is also a factor. Frequent on/off cycles, called “short cycling,” reduces pump motor life further. Short cycling is caused by a failed pressure tank. To read more about it, go to our blog post Why does my well pump turn on and off every time I use water?
• Size of motor - A pump motor with a higher horsepower rating will last longer.
• Quality of motor - A pump motor with higher quality bearings and windings costs more, but has a longer life.
• Weather protection - An above-ground well pump that is near grade and directly exposed to the weather will have a shorter life than one enclosed in a well shed and mounted off the ground.
