Sump Pump Smells: What They Mean and What To Do

If you have a sump pump in your home or business, you know how important it is to keep it running smoothly. Sump pumps keep your basement or crawl space dry and safe from water damage. However, you might notice a strange smell coming from your pump. Foul odors can indicate significant problems, so you should address them immediately. We’ll go over sump pump smells, what they mean, and what to do to fix the problem.

1. Rotten Egg Smell

If your sump pump smells like rotten eggs, it could indicate a sewer line problem or a natural gas leak. A sewer line issue can cause hydrogen sulfide gas to enter the sump pit, which creates foul odors. If you suspect a gas leak or sewage problem, call a licensed plumber or HVAC technician to assess the situation and deal with any hazards.

2. Musty or Mildew Smell

A musty or moldy smell coming from your sump pump could indicate that your basement or crawl space is not adequately ventilated. Mold thrives in damp, dark, stuffy environments. Install a dehumidifier or run a fan in your basement to mitigate mold growth. You should also inspect your home or commercial building’s foundation for cracks or gaps that might let in moisture.

3. Burning Smell

A burning odor from your sump pump indicates an electrical or motor issue. It could mean the motor is overheating or that there’s a problem with the wiring. If you notice this smell, turn off the pump and call a licensed electrician immediately. A reliable electrical service company can get the job done safely.

4. Chemical Smell

If you detect a chemical odor from your sump pump, it could be a sign of contamination in the water. Solvents, pesticides, and gas can seep into the sump pit and create foul odors. In this case, call a professional plumber to check the purity of the water.

5. Sewage Smell

A sewage smell coming from your sump pump indicates a problem with the septic system or sewage line. The sump pump might be improperly directing wastewater to the sewer line or something is blocking the system. If you smell sewage, contact a plumber to inspect and repair your septic or sewage system.

Keep Your Home or Business Free of Water Damage

Sump pumps are essential for keeping your home or business free from unwanted water damage. However, strange smells emanating from your sump pump can indicate a problem.
