Features:

  • 30 YEARS PROTECTING BASEMENTS:

    The Basement Watchdog has been protecting homes for over 30 years and continues to be a market leader. We build the most dependable, user-friendly pumps in the industry using intelligent design, premium components, and quality manufacturing practices that include thoroughly testing every single unit.

 

  • BUILT TO LAST:

    The Basement Watchdog SI series of sump pumps (Models SI-33V, SI-50V) feature an energy-saving, Permanent Split Capacitor (PSC) motor that has carbon/ceramic shaft seals and thermal protection to safeguard the motor. The upper and lower ball bearings ensure the pump runs quietly and extend its life.

 

  • ENERGY-EFFICIENT OPERATION:

    The sump pumps in the Basement Watchdog SI series (Models SI-33V, SI-50V) save you money on your electric bills and reduce their effect on the environment. The SI sump pumps are engineered with eco-friendly PSC motors and dual ball bearings that together deliver industry-leading energy efficiency and savings.

 

  • RUGGED CONSTRUCTION

    The Basement Watchdog SI series of sump pumps (Models SI-33V, SI-50V) are formed out of solid cast iron with stainless-steel fasteners. To prevent airlock and make installation easier, they also include a built-in weephole. The built-in strainer can pass ½" solids, which allows it to function as both a sump and effluent pump.

 

  • PUMPING POWER:

    The ? HP model (SI-33V) in the Basement Watchdog Professional SI series of sump pumps moves a substantial 4,000 GPH at a 0' height (3,200 GPH at a 10' height), and the ½ HP model (SI-50V) handles 4,300 GPH at a 0' height (3,600 GPH at a 10' height).

 

  • PRO-GRADE VERTICAL SWITCH:

    The Basement Watchdog SI sump pumps (Models SI-33V, SI-50V) feature a professional-grade, built-in vertical switch for years of reliable operation in sump or effluent applications.

 

  • WHY THE SI SUMP PUMP:

    The Basement Watchdog Professional SI series of sump pumps comes in a ? HP (SI-33V) and ½ HP (SI-50V) model with a built-in strainer that can pass up to ½" solids, allowing the pump to do double duty as a sump and effluent pump. It includes an integrated, contractor-grade, vertical float switch for reliable activation. The SI pumps are tough, versatile and can pump whatever comes their way.
