When there is power and everything is good, do i need an extra 120Vac pump? or is the system designed to draw power from the batteries ALL the time, even when there is power?
Answer
Thank you for your interest in Sump Pumps Direct. The NexPump Combination Sump Pump System, like other combination systems, are designed to handle your main pump needs along with your backup pump needs. So to answer your question, you do NOT need an additional 120V rated pump.
