Top Reasons For Well Pump Failure

One of the most common questions we are asked by homeowners is simple. Why did my well pump fail? There can be many contributing factors to the failure of your submersible well pump.   Two of the leading factors are age and electrical failure.


  • Age As with anything mechanical in nature, wear and tear is the most frequent cause of well pump failure.  Simply put, well pumps have a lifespan of between 8-12 years.  Of course, some may last longer.  Some may unfortunately last a shorter duration.  The lifespan of your well pump can be dependent on many factors like the quality of your water (especially the amount of sediment present), how frequently the pump is used, and the quality of the installation.
  • Electrical Failure In addition to common wear and tear, electrical failure is one of the leading causes of well pump failures. This can be due to an electrical surge, a short, or even (and commonly) a lightning strike. Lightning strikes can damage the pump motor, and burn the insulation of the pump wire.  Often times if a well pump is struck by lightning it may not immediately stop working.  It is normal for a pump to continue to function for a week or two before the damage caused by the lightning causes total pump failure.
