Sump Pump Replacement in Lowell, answered

Sump pump replacement swaps a failed, worn or undersized pump for a new one in your existing pit, usually with a new check valve and a float test. Replace it if it runs constantly, hums without pumping, cycles on and off rapidly, is rusted or is past its expected life. It is faster and cheaper than a new installation.

Best fit

When do you need sump pump replacement?

Common symptoms and triggers that mean it is time to call:

  • The pump runs constantly even when dry
  • It hums but does not pump
  • Short-cycling on and off
  • Loud grinding or rattling
  • Visible rust or a corroded base
  • It failed in the last storm
  • The pump is many years old and has never been replaced

Lowell-specific note: spring thaw is the test

Greater Lowell sump pumps work hardest during the spring snowmelt and heavy rain, especially near the Merrimack and Concord rivers. Test the pump before spring by pouring a bucket of water into the pit. Make sure the discharge line is not frozen or buried in snow, and that it does not connect to the sanitary sewer.

Cast-iron pumps dissipate heat better and generally hold up longer under heavy use than plastic models. In basements that pump often, the upgrade is usually worth it.
