A sump and pump is a great way for homeowners to protect themselves against damaging basement floods and water leaks. If you have a leaky basement a sump pump may be your best option.

Step 1: Prepare to Install the Pump

Before installing a sump pump you need to figure out if it’s possible to do so. Most homes are constructed on top of gravel, but some aren’t so you’ll want to be sure before you start digging. Contact the builder of your home, or talk to you neighbours with similar houses, to find out. Next you need to find a location for your sump pit. You’ll want to locate it 8” away from a wall in an area that will allow you to punch a hole through the rim joist. Make sure the sump pit is also clear of the sewer line.

Step 2: Breaking Through the Concrete

Next you will have to break through the concrete. The best way to do this is to use an electric jackhammer. Cut the concrete into square pieces or about 8 – 12 inches across, and then move the jackhammer at an angle to pry them up and carry them away in a bucket. Don’t shred the concrete, as this will create a bigger clean-up for you.

Step 3: Digging the Sump Pit

Once you’ve gotten rid of the concrete you can dig the sump pit. You’ll want to dig it 12 inches deeper than the sump liner, then fill it with coarse gravel to create good drainage. Then, put the liner into the hole and put gravel around the edges. Once it’s in place, pour a 6-inch layer of concrete over top of the gravel. Use a trowel to smooth out the top so it’s even with the floor.

Step 4: Install the Sump Pump

Start by threading a 1 ½ inch PVC male adapter into the port, then tighten it with pliers until it’s secure. Use PVC cement to glue a schedule-40 PVC riser to the adapter. Drill a hole through your rim joist to create a path for the PVC pipe to go outside. Finally, assemble your PVC piping so it goes up and then out through the hole you created. Once the pipe is outside glue a 90-degree elbow to the end of it so it points downward. Connect a hose to the piping outside to take the water away from your home.
