What is a Sump Pump?

As evident by the name, sump pumps are small pumps located in the lowest area of your house near the basement. They use a motor that resembles a fan to evacuate the water out of the sump pit or basin. Pipes are present in the pit/basin that help in transporting the water away from your house. There are high chances of your basement being flooded during heavy rainfall. The water from the rain enters your basement as it is below the ground level.

It is best to get sump pumps installed in the basement so you can save yourself from permanently damaging the house.

How To Install A Sump Pump?

A sump pump is placed near the crawl spaces or basement of the house. A hole or pit of almost 3 feet is made from your basement. The pump is fixed into the pit and is connected with a drainage outlet. If you use a pedestal sump pump, it will be placed away from the water. Whereas, if you use a submersible sump pump, it is placed into the water.

The motor can work for 6 to 24 hours depending upon the amount of water stored in the pit. Most pumps are powered by electricity but a battery backup is present too in case of a power outage. Powerful motors can work continuously so you can get rid of all the water in one go. All the water is pumped out and transported to an area that is safe for drainage.

Duty Cycle

Every sump pump will have a different duty cycle depending upon the quality and the motor. A pump with a continuous motor will work non-stop for almost a day or more unless all the water is drained out from the pit. Whereas, the sump pump using the intermittent motor will work only for 18 to 20 hours at the most. You can make it work for more time but this will damage the motor. Overusing the average quality sump pump can reduce the efficiency too.
