Sump Pump Repair

A pump falling behind puts water across a finished basement floor within hours, so it needs attention while the pit is still holding rather than after the carpet is soaked.

When this becomes an emergency

What a pro does

The plumber watches the pump run before deciding anything, because the failure pattern narrows the cause faster than pulling parts. A unit that never starts, one that runs without stopping, and one that short cycles every few seconds all point somewhere different. The float switch gets checked first. It moves more than anything else in the pit, so it's the part that wears out soonest and the cheapest one to put right. If the float is fine, the motor and impeller get tested against how fast water is actually arriving. The discharge line is the piece that catches people here. Winter freezes the outdoor end of it, and a pump pushing into a plugged or iced pipe hums along sounding perfectly healthy while the pit stays exactly as full as it was. Timing follows the season. Runoff from the hills and a fast melt over frozen ground send water at basements in a way that steady rain never does, and perimeter drains that coped all winter can be overwhelmed inside a few days. A backup pump gets discussed anywhere losing power would mean losing the basement, since wind events and a full pit have a habit of arriving together.

Frequently asked questions

That's usually the discharge rather than the pump. A frozen outdoor section, a crushed pipe, or a failed check valve all give you a motor that sounds normal and a pit that stays full, because the water is being pushed and then coming straight back.
It can, and it's one of the more common seasonal failures here. Water sitting in the exposed run outside freezes solid during a cold stretch, and the pump has nowhere to send anything. Routing and slope on that outdoor section are what keep it from happening.
During a rapid thaw, generally. Melt off the higher ground runs across ground that's still frozen and can't absorb it, so it moves sideways to the nearest foundation. That's a heavier and more sustained load on a pump than a summer storm produces.
It keeps the pit under control when the primary can't, most often because the power is out. On a property where a failed pump means a flooded finished basement, that second unit is doing the real work exactly during the hours nobody can respond.
