Sump pump system, including water level sensor shield
The present invention provides a sump pump system, including a sump pump monitor and application. The sump pump system includes a sump pump. Components of the sump pump system are installed in and/or near a sump. The sump collects liquid, such as water, from an inlet pipe. The sump pump is operable to remove water from the sump. The sump pump is fluidly connected to a discharge pipe. The discharge pipe is operable to carry water from the sump pump to a storm sewer or other discharge point.
