How does a sump pump work?
user
Sump pumps are machines that pump water out of the lowest area of a house, known as a “sump” or “basement.”  In the United States and Canada, a sump pump would be driven by electricity from a circuit breaker.

So it helps so the basement does not flood?
user
Yes. When heavy rains fall, the ground outside fills with water and any excess runs into the basement through a drain pipe or through rain that seeps through the ground. The pump raises the water out of the basement and allows the excess to flow into a drain outside the home. If you do not have a sump pump, the basement floor can flood, and eventually the water will seep into the main floor of the home and cause damage.

So does it keep up with the water?
user
Usually, but there can be more water than a sump pump can handle. If this happens, you’ll need to hire someone to pump the water out manually. A sump pump will likely not keep up with a flood of water, since pumps can only handle a limited amount of water at a time.

Some sump pumps are timed to operate automatically, without any need for human action. Other sump pumps, known as “manual” or “floor-mounted” pumps, require periodic, human-driven maintenance. For instance, if a valve for the pump gets stuck or gets clogged with debris, the pump won’t be able to pump the water out.  A user would need to go down into the basement and remove the clog to keep the pump operational.
