A sump pump is a device that pumps water out of a basement or crawl space to prevent flooding. It is installed in a sump pit, which is a hole dug in the floor of the basement or crawl space that collects water from the surrounding area. The sump pump then pumps the water out of the pit and away from the home.
It is recommended to test your sump pump at least once a month by pouring a bucket of water into the sump pit to ensure that it is working properly. It's also a good idea to test your sump pump after heavy rain or flooding to make sure it's still in good working
The size of sump pump needed depends on the size of your basement or crawl space, the amount of water that needs to be pumped, and the rate at which water enters the sump pit. A professional plumber or contractor can help determine the appropriate size for your home.
