Yearly Well Maintenance For Home Owners

  • Preventive maintenance can help your well system last longer and cost less.

  • Typically, an economy submersible pump will last 5-10 years, midgrade submersible pump lasts 10-15 years and a quality submersible pump can last 20+ years.


  • Usually, the lifespan of a pressure tank will be shortened due to incorrect air pressure. 99% of residential pressure tanks should have air pressure of 28-30 PSI.

  • Typically an economy pressure tank can last 5-7 years.

  • We normally install a better quality pressure tank that lasts 15-20 years on average.

  • Protects against water hammer. Water hammer is a thump or hammer like noise that occurs when a pump comes on or off.

  • Minimizes pump cycling. This prevents frequent starts and stops, protecting pumps from damage.

  • Maintains a desired range of water pressure in the water system.
