How Does a Sump Pump in a Basement Work?
A sump pump is a small pump installed in the lowest part of a basement or crawlspace. Water flows into the sump pit through drains or by natural water migration through the soil. The sump pump's job is to pump the water out of the pit and away from the building so the basement or crawlspace stays dry.

Regarding this, does every basement need a sump pump?

Typically housed in a specially constructed pit below the main surface of a basement, a sump pump collects excess water from drains and pumps it out of the pit and away from the house. Since not all houses are likely to flood, not all homes need sump pumps.

Likewise, how do I drain my basement sump pump? Attach a garden hose or a sump hose to the fitting on the top of the pump and tie a nylon rope to the top of the pump. Most pumps have a place on top of the pump where you can tie the rope. Position the end of the hose away from the house on a grade where the water can drain into a gutter or storm sewer.

The pipe usually has a one-way valve called a check valve at the pump end to keep the water from flowing back into the pit. Most sump pumps turn on automatically through a float activator arm or a pressure sensor. A buoyant ball floats on top of the water, manually moving the arm as the water level rises.

How often should a sump pump run?

There's a delay after rain starts before the standup area gets enough water in it for the pump to run. Then it runs as often as every eight minutes or so. It will keep running after the rain stops, as the ground keeps releasing water into the standup area.
