Uncover the truth: what is sump pump short cycling and how to fix it now

Sump pump short cycling is a common issue that occurs when a sump pump turns on and off frequently in a short period of time. This can be a problem because it can put unnecessary wear and tear on the pump, reduce its lifespan, and increase energy consumption.

Causes of Sump Pump Short Cycling

There are a number of factors that can cause sump pump short cycling, including:

• Undersized sump pump: A sump pump that is too small for the size of the sump basin will not be able to keep up with the inflow of water, causing it to turn on and off frequently.
• Clogged discharge line: A clogged discharge line can prevent the sump pump from draining water properly, causing it to turn on and off frequently.
• Faulty check valve: A faulty check valve can allow water to flow back into the sump basin, causing the pump to turn on and off frequently.
• Air leak in the suction line: An air leak in the suction line can cause the pump to lose prime, causing it to turn on and off frequently.
• Improperly installed sump pump: A sump pump that is not installed properly may not be able to drain water properly, causing it to turn on and off frequently.

Signs of Sump Pump Short Cycling

There are a number of signs that can indicate that your sump pump is short cycling, including:

• Frequent on/off cycling: The pump turns on and off more than once per hour.
• Short run times: The pump runs for only a few seconds or minutes at a time.
• Humming or buzzing sound: The pump makes a humming or buzzing sound when it is running.
• Increased energy consumption: You notice an increase in your energy bills.

Consequences of Sump Pump Short Cycling

Sump pump short cycling can have a number of negative consequences, including:

• Premature pump failure: Short cycling can put unnecessary wear and tear on the pump, causing it to fail prematurely.
• Increased energy consumption: Short cycling can increase energy consumption, as the pump is running more frequently.
• Flooding: If the sump pump fails due to short cycling, it may not be able to pump water out of the sump basin, which can lead to flooding.

How to Fix Sump Pump Short Cycling

There are a number of things you can do to fix sump pump short cycling, including:

• Install a larger sump pump: If your sump pump is too small, you can install a larger pump that will be able to keep up with the inflow of water.
• Clean the discharge line: If the discharge line is clogged, you can clean it out using a snake or a wet/dry vacuum.
• Replace the check valve: If the check valve is faulty, you can replace it with a new one.
• Seal any air leaks in the suction line: If there is an air leak in the suction line, you can seal it using a sealant or tape.
• Reinstall the sump pump: If the sump pump is not installed properly, you can reinstall it according to the manufacturer’s instructions.

How to Prevent Sump Pump Short Cycling

There are a number of things you can do to prevent sump pump short cycling, including:

• Choose the right size sump pump: When choosing a sump pump, be sure to select one that is the right size for the size of your sump basin.
• Keep the discharge line clear: Regularly inspect the discharge line for clogs and clean it out as needed.
• Test the check valve: Regularly test the check valve to make sure that it is working properly.
• Inspect the suction line for air leaks: Regularly inspect the suction line for air leaks and seal any leaks that you find.
