You would need a sump pump repair if the sump pump in your basement is not pumping out water. The purpose of a sump pump is to drain excess water that is part of your waterproofing system.
The sump is the oil reservoir. An oil pump lifts the oil from the sump and forces it under pressure through the engine. The oil then returns to the sump to be used again. Some sumps have fins on then - this acts as a cooler to help cool the oil in the sump.

"A sump is a low space that collects any often-undesirable liquids such as water or chemicals. A sump can also be an infiltration basin used to manage surface runoff water and recharge underground aquifers.One common example of a sump is the lowest point in a basement, into which water that seeps in from outside the house flows. If this is a regular problem, a sump pump that moves the water outside of the house may be used."--wikipedia
It keeps the water that is pumped out from flowing back into the sump when the pump shuts off. Most sumps discharge several feet above the hole the pump sits in. If there was not a check valve the sump would just refill and pump out the water over and over.
For best drainage results, the sump pump should be placed below the rest of the floor. It should be set up to drain outside the house. The hose should be far enough away from the window that it does not leak back inside.
