Professionally once a year, and test it yourself with a bucket of water twice — before monsoon season and again before winter. A sump pump that has never been tested is a pump whose condition nobody actually knows.

The Two-Minute Homeowner Test

Pour a five-gallon bucket of water into the pit. The float should rise, the pump should start, water should clear, and the pump should shut off cleanly. If any part of that does not happen, you have found a problem on a dry day rather than during a storm. Do this in late spring before monsoon season and again in fall.

What Annual Professional Service Covers

  • Clean sediment and debris from the pit — the leading cause of stuck floats and clogged intakes
  • Inspect and test the float switch through a full cycle
  • Check the impeller and intake screen
  • Verify the check valve holds so water does not flow back into the pit
  • Inspect the discharge line for blockage, damage, and freeze exposure at the outlet
  • Test electrical connections and the GFCI circuit
  • Test battery backup capacity, if you have one
  • Measure run time and cycling against expected performance

When to Service More Often

Pumps running frequently, pits that collect a lot of silt, homes in low-lying areas or drainage paths, and any pump past seven years. Also after any major storm event, which is when problems reveal themselves.

The Timing That Matters in New Mexico

Monsoon season is what tests a sump pump here — a summer downpour delivers a large volume very quickly. Service in spring, before that season starts, rather than after you discover the pump did not keep up. The fall check matters too, since a discharge outlet holding standing water can freeze solid overnight and back water into the pit.

The Upgrade Worth Making

A battery backup pump. Storms cause both the water and the power outage simultaneously, and no amount of maintenance helps a pump with no electricity. Add a water alarm while you are at it.
