Reasons for Sump Pump failure 2 of 2

A replaced sum pump, with the failed one sitting next to it.

1. Did Not Install a Check Valve on the Discharge Line

When the check valve is not installed on your sump pump’s discharge line, a back flow of water can cause the pump impeller to rotate backwards and unscrew off the motor shaft. If this occurs, the motor in your sump pump will sound like it is running, but it will not be pumping any water out the discharge line. A check valve is the best way to prevent this type of back flow problem.

2. No Air Relief Hole in Discharge Line

A hole should be drilled between the pump and the check valve to prevent air pressure from building up. Without the relief hole, pressure will build up in the discharge line and force the sump pump to work harder. This additional burden on the sump pump will result in a shorter overall life.

3. Setting Your Sump Pump in Gravel or Dirt

Some will pack their sump pumps in gravel or dirt to make it a snug fit. The gravel or dirt may cause the sump pump to fail, because the on/off switch and the float arm will be interfered with.

4. Product Defect

It’s unlikely, but your sump pump could be defective. If you install it yourself, you will want to test it immediately to make sure it’s working. If it’s not, take it back to the store where you bought it, and exchange it for a different one.

5. Improper Installation

If you have ruled other problems out, you should look to make sure your sump pump is installed correctly.  Having the installation inspected by a licensed plumber can help determine if the sump pump will work properly when needed.
