Most Basement Watchdog AC sump pumps (BWSS, BWT, and SIT series) are rated for continuous duty, so if needed they can run nonstop for extended periods.

Continuous duty means they:

• are built to run continuously—24 hours a day, 365 days a year
• are durable and reliable
• have an extended life when used in a sump application

Not all AC sump pumps are rated for continuous operation—only continuous-duty pumps are designed for 24/7 use, while standard pumps are intended for intermittent, shorter cycles. Continuous-duty pumps such as The Basement Watchdog primary pumps (BWSS100, BWT050, BWT075, SIT-33D, and SIT-50D) are engineered with features like upper and lower sealed ball bearings creating less heat and dual shaft seals to withstand constant operation, whereas standard pumps can overheat and become damaged if run for too long. It is crucial to check the pump’s specifications to determine if it has a continuous-duty motor and is suitable for extended use.
