How do you test a sump pump?
Pour enough water into the basin to raise the float and confirm that the pump turns on, empties the pit, and shuts off cleanly. Listen for grinding, rattling, or buzzing. Watch the float to make sure it moves freely and does not catch on the basin wall or the pump cord.
What maintenance should happen before spring thaw?
Check the pump, outlet, discharge line, downspouts, and backup battery before snowmelt and heavy rain arrive. Spring thaw can add water slowly for days, so a weak pump may run often before anyone notices a problem.
When should maintenance turn into a quote request?
Request quotes when the pump is old, noisy, cycling constantly, slow to drain, or protecting finished space without backup. A provider can compare replacement cost against the risk of basement water damage.
