Any time your sump pump will not turn on and run, unfortunately, you have a major issue on your hands. There are actually a number of reasons that your sump pump may be experiencing power issues including the float switch being stuck or broken, a jammed impeller, a potential loose electrical connection, a burnt motor, or your sump pump has just plain hit the end of its lifespan. Whatever the case, if your pump is older and not running, you may need to think about Pro Sump Pump Installation and Replacement Services from PlumbV.
Contrarily, if your sump pump is always running, and never seems to turn off, this is also an issue! This is normally due to a float switch issue, which will need professional assistance from PlumbV. If your sump pump is not turning on at all or running constantly, repairs can be possible, but you may need to start thinking about replacing the machine completely.
