Why Your Sump Pump Is Overworking

Most electromechanical systems, including the sump pump, experience wear and tear during operations. The more the pump operates the more wear and tear it operates. Below are some of the reasons your sump pump might be overworking.

Excessive Flooding

Under ideal situations, the sump pump should switch between periods of rest and operation. Unfortunately, excessive flooding will force the sump pump to operate continuously. Such incessant running will overwork the pump, increase the risk of malfunction, and shorten its lifetime.

Undersized Pump

A sump pump's capacity is the volume of water it can pump within a given time. The right sump pump should handle the volume of water your home is likely to experience without getting overwhelmed. Some of the factors that affect sump pump sizing include:

  • The local climate — specifically the amount of rainfall per season
  • The size of the sump pit
  • The vertical lift (how high you want to pump the water)
  • The diameter of the discharge pit

Your sump pump will strain if it cannot handle the volume of water in your house.

Undersized Sump Pit

The sump pit is a literal pit that collects floodwater to activate the sump pump. You dig the sump pit in the lowest part of the basement. The lowest part of the basement is where the water will collect in case of flooding.

As previously mentioned, a sump pump wears out fast if it runs continuously. The same thing happens if the sump pump has to turn on and off too frequently. The pump will have to switch on frequently if the sump pump is too small and fills with water too fast.

Broken Check Valve

The check valve allows water to flow in one direction — out of the sump pit but not back in. The single direction flow ensures that the water stays out once the pump forces it out.

A valve malfunction may allow water to flow in both directions. If that happens, water will be flowing back into the sump pit and forcing the sump pump to run longer than usual. Again, the continuous operations overwork the sump pump.

Float Switch Malfunction

The float switch turns on the pump if it detects water in the sump pit. The switch also turns off the pump if there is no water in the sump pit. A defective float switch, however, might fail to switch off the pump even if there is no water in the sump pit. As a result, the pump will overwork by running even without pumping any water.
