How to Install a Pedestal Sump Pump

A sump pump comes in two different varieties: the pedestal sump pump and the submersible pump. The water intake of the pedestal pump sits on the bottom of your sump and the motor of the pedestal pump is above the sump's water line. Here are instructions on how to install a pedestal sump pump.

Tools and Materials Required

  • Pedestal sump pump
  • Check valve (optional)
  • Schedule 40 PVC pipe, 6 feet by 1 1/4 inch or 1 1/2 inch diameter
  • Male PVC adapter to fit PVC pipe
  • PVC solvent
  • Screwdriver
  • Pliers or adjustable wrench
  • Hacksaw
  • Utility knife
  • Bucket or garden hose
  • Water
  • Tape measure

Step 1: Remove Existing Sump Pump

Take out the existing sump pump and discard it. To do this, disconnect the electric line from the sump pump and then disconnect the discharge line from the pump. The discharge line is held by a flexible rubber root. The rubber boot is held in place with a clamp system.

Step 2: Cleaning the Sump

Now that the pump is removed, clean out all the debris, soil, small gravel or sand from the sump. Once cleaned, check to see that the depth of the sump is adequate to the pump's specifications. Twenty-four inches is generally the depth of a sump.

Step 3: Measuring the Length of the PVC Pipe

Using the right sized PVC adapter, thread it into position on the discharge outlet. Once threaded in, tighten it up with either the pliers or adjustable wrench. Place the pedestal sump pump into position. Now start measuring the length of PVC pipe needed so it will reach from the exterior to the end of the discharge line.

Step 4: Cutting the PVC Pipe

Remove the pedestal sump pump and cut the measured length of PVC pipe with a hacksaw. Using the utility knife, clean the cut and smooth the edges. Cement the PVC length into the adapter using the PVC solvent. Continue installing once the joint has set.

Step 5: Follow the Directions to Install Float Switch

Follow the manufacturer's instructions on installing the float switch. This can be an involved process, so read the directions carefully.

Step 6: Positioning the Sump Pump

Position the pedestal sump pump on the floor. Align the outlet line and discharge pipe and install the check valve if it is used. Using the flexible connector, connect the outlet line with the discharge line. Make sure that your float switch has room in the sump to float and move around freely.

Step 7: Plugging in the Pedestal Sump Pump

Now plug the sump pump into the grounded outlet. The grounded outlet is protected by the ground-fault circuit interrupter. Do not ever try to connect the sump pump to an extension cord.

Step 8: Testing the Pedestal Sump Pump

Tip water inside your sump so you are able to test your sump pump's operation. You also have to adjust your float switch to the manufacturer's specifications. Once tested and working, you should feel satisfied that you installed your own pedestal sump pump.
