Step 5 · Install the New Sump Pump
Carefully lower the new pump assembly into the center of the sump pit. Ensure the pump sits flat and level on the bottom of the pit, not on any debris. Crucially, check that the pump's float switch can move freely up and down without touching the sides of the pit or any other pipes. Once positioned, re-align the pump's discharge pipe with the main drain line. Slide the rubber coupling back into place so it bridges both pipes and tighten the hose clamps securely with your screwdriver or nut driver.
