The Basement Watchdog 1 HP submersible sump pump has the highest capacity of all of the pumps in our Basement Watchdog line. It features a powerful and energy-efficient permanent split capacitor (PSC) motor providing 6,540 GPH at 0 ft. lift and 4,440 GPH output at 10 ft. lift. The 2-inch discharge helps maximize output. Simply put, the BWSS100 moves water out fast, so your basement stays dry. Unlike other similar sump pumps, this one uses only 6.3 Amps, paying for itself in energy savings. The stainless steel and cast iron construction, along with upper and lower ball bearings, and dual carbon ceramic shaft seals, protect the motor for years of service. The caged dual float switch provides not one but two floats for added protection, while the protective cage around the float prevents debris or other wires from interfering with the floats. Easy to install, the caged dual float switch can be adjusted to any level. The vented and curved bottom prevents debris from building up under the primary float. The float switch is easy to install and can be adjusted to any level. Get the best level of protection from flooding with this high-capacity sump pump.. Amperage (A): 6.3 A. Cord Length (ft.): 10.
