The Basement Watchdog SP series of sump pumps (Models SP-33T, SP-50T) are built to last, featuring an energy-saving, Permanent Split Capacitor (PSC) motor with 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.

The SP sump pumps save you money on your electric bills and reduce their effect on the environment. Engineered with PSC motors and dual ball bearings, they deliver industry-leading energy efficiency and savings.

The Basement Watchdog SP sump pumps (Models SP-33T, SP-50T) feature a heavy-duty, built-in tether switch that is easy to adjust and provides years of reliable operation. The ⅓ HP model (SP-33T) provides 3,700 GPH at a 0' height (2,800 GPH at a 10' height), while the ½ HP model (SP-50T) delivers 3,900 GPH at a 0' height (3,100 GPH at 10' height).

If your power goes off during a big storm or a torrential rain is more than your primary pump can handle, your basement can still flood. Avoid the expense, hassle, and health hazards of cleaning up a flooded basement by purchasing a Basement Watchdog backup pump to work with your SP pump to keep your basement dry.

The Basement Watchdog SP series, our most economical sump pump option, comes in ⅓ HP (SP-33T) and ½ HP (SP-50T) models. The pump's body is constructed out of thermoplastic with stainless steel fasteners for superior durability, and it includes a fully adjustable tether switch.

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.
