    First of all, if your sump pump is smoking (or on fire) then you need professional help or even the fire department. If possible flip the breaker that controls your pump or if the smoke is just coming from the actual pump, unplug it immediately.

    Smoke means you are at risk of starting a fire – or one has already started. While this may seem scary, it is important to never throw water on anything that uses electricity to extinguish a fire. You should always keep a smoke detector nearby in case of pump problems.

    Can a Sump Pump Catch Fire?

    Yes – sump pumps (and basins) can catch fire! The most common cause is older, overworked pumps. Another common cause of basement fires is low-quality electrical work to power the pump, alarm, and battery. Also, remember to ensure you use the right size extension cord.

    Pump fires rise as older homes (and water pumps) age, and maintenance gets ignored. Always perform yearly upkeep, clear your pit of debris, and monitor its workload.

    Common Causes of Smoke

    Next – let us explore some ways you can prevent the sump pump from steaming and smoking. If you notice a burning smell or the pump is hot to the touch you might have a big problem on your hands.

    1. Smoke Detector and Fire Extinguishers

    Although you may have good fire-preventative habits upstairs, it is easy to forget about a basement you don’t use often.

    Keeping a fire extinguisher rated for electrical fires and a smoke detector in sync with upstairs sensors is the best way to protect your family from a fire caused by a sump pump.

    2. Lack of Lubrication

    If your sump pump runs out of oil, parts can grind together enough to cause smoke. If this has progressed too far, your entire sump pump may need replacing.

    This is one of the reasons why making sure your pump is holding oil and repairing leaks immediately is so important to the life of your pump.

    3. Stuck Float

    If your sump pump float is stuck, your pump may not know how to cut itself off. A stuck float happens most often with tethered floats attached to the sidewalls of your sump pit.

    If your sump pump runs for too long with no break, then it will become hot and start steaming and smoking.

    4. Electrical Issues

    A cracked sump pump assembly can lead to water getting into areas of the sump pump that are meant to remain dry at all times. This can lead to corrosion and electrical shorts in the pump.

    Wiring in your home can also be a factor. This is most common in older homes that have outdated wiring, but even modern homes can experience electric current issues.

    5. Frozen or Clogged Discharge Pipes

    A frozen discharge pipe can cause a pump to run constantly. The water around the pump may also feel warm. This, of course, happens most often during particularly cold weather.

    During colder and wetter periods, it is good to check your discharge pipe regularly for ice and if necessary install accessories to prevent ice buildup. Sometimes just keeping your basement a bit warmer is not enough.

    A sump pump specialist can help determine what can be added, so you don’t have to worry every time the temperature dips down.

    Sump Pump Hot to the Touch

    Some pumps run hotter than others, but something may be wrong if your pump is hot to the touch. It is important to remember that pumps have powerful motors and can push large amounts of water per hour so that they will get warm after extended run times. If the pump is hot, it is a sign that the motor is overworked and may burn out soon.

    Sump Pump Burning Smells

    If you go into the basement and smell a burning smell from the sump pump, the motor might be at risk of burning out. If your sump pump is the wrong size, the engine may be working too hard after running for extended periods – causing a burning smell and risking a fire.

    Sump Pump Fire Awareness

    Sump pump fires are increasingly common. These happen the most during colder months when things become frozen, or there are high water table conditions. Good sump pump maintenance and taking some precautions in case of fire can avoid catastrophe. 

    If you have just moved into a home and don’t know much about your sump pump, then you may want to have it inspected before the start of wet weather conditions. A small amount of prevention can go a long way if your sump pump is smoking.

    What About Steaming Pumps?

    When your pump is working too hard it may start to steam. This is a good sign that there is a mechanical problem or you just need a more powerful pump. Keep an eye out for steam coming off your pump as well as water in the pit. If it is steaming it will be hot to the touch!
