The answer to 'why is my sump pump' is that there are several common reasons why a sump pump may not be working properly. The most frequent issues include a faulty or malfunctioning pump, a clogged or blocked intake, a power outage, or a problem with the float switch that triggers the pump to turn on.
Some key symptoms to look for include the pump not turning on at all, the pump running continuously, or the pump not pumping out enough water. Solutions can range from simply clearing debris from the intake to replacing the pump motor or float switch. In some cases, the entire sump pump system may need to be upgraded or replaced.
