Why Does My Sump Pump Smell Bad?

Have you been avoiding going down to your basement because there is a nasty odor coming from the sump pump? Don’t let the smell take over your home, there are several ways you can take care of the issue yourself without having to call the plumber.

An unpleasant odor coming from your sump pump can also be an early detection that there is something wrong with the system. Often, an odor can indicate that the sump pump is not functioning properly so it’s best to tackle the smell head on and with your nose plugged.

A simple and easy fix to the odor being released from the sump pump is the lack of water in the pit. If it hasn’t rained much then the sump pump has not had the chance to fill with water and the water that was in it has evaporated, allowing the gas from the sewer to escape.

Should you find that this is the reason for the smell, simply pour a bucket of water into the pit until the sump pump turns on. The smell should go away once the pit becomes moist. There should always be a little bit of water in the pit to keep the odor released by the sulfur dioxide at bay.

Another potential cause is an issue with the float switch. The float switch is a piece of plastic tubing typically filled with air. The float switch sits in the pit and as the water fills the pit, the float switch rises – once it rises to a particular spot, it turns the sump pump on and the water drains, lowering the water and the float switch back to the bottom, turning off the sump pump.

If the float switch isn’t working properly, it might turn off the sump pump before all the water has been released from the pit. This problem will allow a decent amount of water to sit in the pit for a long period of time. When this occurs, the water will become stagnate and algae will form and grow, giving off a nasty odor. To fix this issue, simply replace or adjust the position of the float switch.

Getting rid of the odor will most likely uncover a problem with your sump pump so don’t let the odor get you down or keep you from having to pay for an issue that could have been prevented.
