what is the difference between a sump pump and ejector pump?
My crawlspace has flooded (probably due to heavy rain and/or leak in the foundation). I was asked if I had a sump pump. I know that I have an ejector pump but it does not appear that I have a sump pump. What is the difference between the two? What is each’s purpose. Should homes have both?

An ejector pump is used to pump sewage from toilets in the basement up to the sewer line. A sump pump removes water that can flood your basement.
a sump pump is a permanent fixture usually used to lift water to pipe level where a floor drain is needed and the main pipe is higher than the floor.
An ejector pump is a strong pump usually powered by gasoline used to quickly drain highly flooded areas.
A sump pump is a pump used to remove water that has accumulated in a sump pit. A sump pit, commonly found in the home basement, is simply a hole to collect water. The water may enter via the perimeter drains of a basement waterproofing system, funneling into the pit, or may arrive because of rain or because of natural ground water, if the basement is below the water table level.
Plumbing drainage and venting systems maintain neutral air pressure in the drains, allowing flow of water and sewage down drains and through waste pipes by gravity. As such, it is critical that a downward slope be maintained throughout. In relatively rare situations, a downward slope out of a building to the sewer cannot be created, and a special collection pit and grinding lift ’sewage ejector’ pump are needed.
