Step 2 · Disconnect the Discharge Pipe

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Locate the check valve or rubber coupling on the vertical discharge pipe above the pump. A check valve prevents water from flowing back into the pit. Place a bucket nearby to catch water. Using a flathead screwdriver or a nut driver, loosen the two metal band clamps on the rubber coupling that connects the pump's pipe to the main drain line. Once loosened, you can gently pull the pipes apart. Be prepared for water to spill out from the section of pipe above the check valve.
