Step 2 · Disconnect the Discharge Pipe
Locate the discharge pipe coming from the pump. You will likely see a check valve a foot or two above the sump pit cover. This valve prevents water from flowing back into the pit after the pump shuts off. Your pipe is likely connected above this valve with a rubber coupling held by two hose clamps. Using a flathead screwdriver or a 5/16" nut driver, loosen both metal hose clamps on the coupling until the coupling can be moved freely. You may need to gently wiggle the pipe to separate the two sections.
