The answer to 'why is my sump pump constantly running' is that the sump pump is likely responding to an excessive amount of groundwater or rainwater entering your home's foundation. This can be caused by heavy rainfall, a high water table, or a leak in your home's plumbing system. A constantly running sump pump is a sign that there is an issue that needs to be addressed.
Some common causes of a constantly running sump pump include a clogged or malfunctioning pump, a problem with the float switch, a crack in the sump pit, or an issue with the drainage system. It's important to identify and fix the root cause to prevent further damage to your home and ensure the sump pump is working efficiently.
