Heavy Rains in Chicago can Lead to Sump Pump Overflow

Winter may technically be over, but the threat of water damage is ever-present. Many people think that once the snow melts away, the threat of basement flooding is gone. This, however, could not be further from the truth. Heavy rains throughout the Chicago area prove that often. sump pump overflow chicago

Your sump pump is your last line of defense against flooding. If your sump pump fails during a storm, water damage could be in your future. In fact, sump pump overflow is one of the leading causes of basement flooding in the Chicago area.

According to the Insurance Information Institute (III), water damage, including sump pump overflow, accounts for 26% of all residential insurance claims and the average water damage claim is $5,531. Just a few inches of water can cause thousands of dollars in damage if not rectified quickly by a professional water damage restoration company.

Causes of Sump Pump Overflow in Chicago

  • The number one reason behind sump pump overflow is an electrical outage. If it is storming and you lose power, your sump pump also loses power, which can spell disaster. You can combat this by having a battery backup system in place. This ensures your sump pump works when you need it most.
  • As the ground thaws after this seemingly endless winter, the soil becomes overly saturated with water. This, coupled with heavy rains, means one thing: pooling water. Once water begins to collect, it finds the easiest path to flow, which is typically along your home’s foundation, down into your basement, and into your sump pump basin. As groundwater levels rise, it is diverted to the sump pit. When this water reaches the “critical level,” the sump pump is activated and water is diverted away from the home. When a sump pump fails, this water continues to rise until it reaches the basement floor level, flooding your home.
  • Another common problem with sump pumps is neglect. When was the last time you tested your sump pump? Does it work? It is a good idea to test your system AT LEAST annually. So put it on your spring cleaning checklist, because April showers can bring more than just May flowers. They can also lead to water damage.

Sump pump water damage chicagoAdditional causes behind sump pump overflow include:

  1. A Bad Discharge Pipe: Your discharge pipe is supposed to take water safely away from your house. If it fails to do so, that water will quickly find its way back into your basement.
  2. Stuck Float Valve: If the float valve is stuck, your sump pump will not work properly.
  3. Failed Check Valve: If the check valve is clogged, your sump pump will not work properly as well.
  4. Unplugged: If your sump pump is accidentally unplugged, it cannot do its job.


Prevent Sump Pump Overflow

Like anything, your sump pump requires regular maintenance, including:

  1. Ensure the sump pit is free from debris. Often, items stored around the pit can fall in and hinder the float mechanism. When this happens, your sump pump may fail to spring into action.
  2. Test the float. To do this, fill the pit with water and make sure the pump both starts and stops as it should.
  3. Check that valves are installed improperly. These valves ensure that when the pump is not running, water does not find its way back into the sump pump.
  4. If the sump pump has stopped suddenly or has started making a whining noise, it may be because the impeller has become clogged. If this is the case, clean the impeller.
  5. If you notice an oily residue on the surface of the water, check your oil seal. A faulty oil seal may cause the motor to burn out.
  6. Remember, your sump pump runs on electricity. Because of this, it is a good idea to have a backup generator. After all, power outages and severe storms go together like peanut butter and jelly.
