Hi all. So after thinking about installing a backup sump pump (Zoeller Aquanot system), I decided I wanted a backup system that uses an inverter in its controller to switch between AC/DC so it will only fire the DC battery if the house AC power is out. Most pumps don't have this capability so searching and found a company named US waterproofing that supplies these AC/DC backup pumps. Does anyone have experience with this company and if so how about their sump pumps? Are they good? Not a ton of reviews out there for their pumps just basement waterproofing jobs and things of that nature. Any intel is greatly appreciated.
