Sump Pump Troubleshooting

Sump Pump Size

• The strength of a sump pump is determined not by its physical size but rather its horsepower. In general, the larger and deeper a basement is and the closer the groundwater source, the more power will be needed to pump out excess water. Thus, a sump pump with a higher horsepower rating is best when such measurements are larger.

  If a sump pump is in good condition, yet it seems the device isn't able to drain a basement sufficiently, consider replacing the pump with a version that has more horsepower. Packaging often includes information to help consumers choose the most appropriate strength.

Sump Hole Size

• To increase the efficiency of a sump pump and prolong its life, the sump hole should be no less than 18 inches in diameter and 2 feet deep. These measurements allow adequate room for the pump itself and related attachments, as well as the water that usually remains in between pumping cycles. Sump holes that are too small can lead to mechanical problems, such as unnecessarily frequent pumping.

Temperature

• Sump pumps that don't have built-in thermal sensors or malfunctioning sensors can overheat. To correct the issue, simply turn the pump off so it can cool down.

  Overly cold temperatures can also affect sump pumps when the exit pipe that drained water travels through freezes from the outside. Installing a Freeze Stop, a product that provides an alternative exit route, can prevent water from backing up and flooding a basement in such circumstances.

Switch Malfunction

• Sump pumps are able to automatically turn on and off when required due to a float arm that activates the on/off switch in the appropriate situation. Pumping malfunctions often result when the float arm is disturbed or misaligned, thereby preventing it from operating the switch. To verify and solve this problem, check to see if the float arm is in the proper position and if there is any debris inhibiting its movement.

Clogs

• Debris can not only hinder switching, but it can also cause clogs in the sump pump system, ultimately leading to backed-up water and flooding. Periodically inspect the sump hole, check valve, and pump lines to make sure they're free of blockages.
