The Basement Watchdog
Our highest-capacity AC primary pump, the BWSS100, is constructed from cast iron and stainless steel, and includes a caged Dual Float Switch, ensuring it activates the pump when needed.
The Basement Watchdog BWSS100 1 HP AC primary sump pump features 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.
The Basement Watchdog 1 HP BWSS100, our top-of-the-line AC primary sump pump, features a stainless-steel housing and cast-iron volute for the ultimate in durability.
The Basement Watchdog BWSS100 1 HP AC primary sump pump saves you money on your electric bills and reduces its impact on the environment. The pumps are engineered with eco-friendly PSC motors and dual ball bearings that together deliver industry-leading energy efficiency and savings.
The Basement Watchdog BWSS100 1 HP AC primary sump pump includes a caged, microreed Dual Float Switch. We introduced this technology, proven reliable in other uses for over 50 years, to the pump industry and improved it by including two floats. Simply stated: if one float is good, two are better.
The Basement Watchdog BWSS100 1 HP primary sump pump is our largest model. It handles a hefty 6,540 GPH at a 0-foot lift and 4,440 GPH at 10-foot height, giving you peace of mind during even the most severe storms.

A unit of power that indicates how much work a pump can perform when connected to a working wall outlet. The higher the horsepower, the more powerful the pump is, allowing it to move more fluid, overcome greater pressure, or lift fluid to higher elevations
How are pumps cooled? Most pumps are oil filled, using dielectric oil to draw heat from the motor and lubricate the bearings. That oil is in contact with the housing of the pump, which is cooled by the groundwater in the pit. Water-cooled motors have both more efficient motors and better bearings, which create less heat and no need for cooling oil. The motor is pressed directly against the housing, which is cooled by the groundwater in the pit. Note: A small amount (less than 1 oz.) of food-grade oil is in the bearings of a PSC motor for lubrication, not for cooling the pump.
Basement Watchdog pumps incorporate advanced Permanent Split Capacitor (PSC) motors for energy efficiency and reliability vs. the older style shaded-pole motors.
A float switch is the component of your sump system that turns on the pump. Most of our primary pumps use the super reliable Dual Float Switch to activate the pump.
The pump discharge is the plumbing, typically 1½-inch PVC pipe, that carries the water out of the house or building, away from the pump and sump pit.
The pump housing is the outer casing of the pump that encloses the pump motor.
Pump seals are the internal seals that prevent moisture from reaching the motor or any electrical components of the pump.
Bearings are mechanical components that support the rotating shaft of the pump, allowing it to spin smoothly while minimizing friction and wear. Bearings are essential for maintaining the pump’s efficiency, reliability, and longevity.
An impeller is a rotating disk that has blades, or vanes, which move the water using centrifugal force up and out through the discharge pipe.
A strainer is a filtration device, built into the base of Basement Watchdog pumps, which prevents the intake of objects that can harm the internal components of a pump.
A fastener is a component, such as a screw, that holds other components together.
Pump Flow @ 10 Feet (GPH) is a measure of the amount of water (gallons per hour) that a pump can move through a 10-foot vertical discharge pipe before the water exits the home or building.
Max head is the maximum vertical height a pump can push water straight up against gravity. It is the point at which gravity takes over the outflow in the discharge.
