Replacing a Sump Pump

Sump pumps remove water from basements, crawl spaces or any area below the discharge line that exits the home.

This guide outlines the procedures for installing or replacing a sump pump in most residential applications.

Unplug the sump pump and disconnect the discharge line entering it. You may need to use two pairs of water-pump pliers.

Make sure the new pump sits level in the pit and use plastic or composite shims to level if necessary.

• Reuse the old piece of discharge line from the old pump or cut a new piece if needed.
• A check valve will prevent water from flowing from the discharge line back into the pump when it cycles off, reducing the chance of flooding and improving the
lifespan of the pump. If your new sump pump does not include an integrated check valve, consider adding one to the discharge line in this step.
• Connect the outlet pipe to the main discharge line, either by tightening a union or by slipping on a rubber fitting and tightening the hose clamps.
