Comments about Wayne Sump Minder 12V Battery Back-Up:

Overall very happy with the install, big thing is that ABT is the only reseller that I know, in chicago land area that has these IN STOCK, available for Pickup any day or can be shipped. Performance-wise at 13 TDH (total Dynamic Head) this pumps close to 25-30 Gallons per Minute. Seems like a nice concise package, and it has features found on $1000 models (i.e. phone capability , and auto run test every two weeks)
I ran a separate line to the sewer system, which is recommended method. There seems to be no way to adjust the 15 second run time, ie. you have to place your float (REED switch) so that It does not allow the pump to run dry (which is bad for the pump). Pump will BEEP and Complaint if there is no power or there is a problem with a primary pump. Great Product, hope it lasts. Got the deep cycle Battery (also available at ABT)

Service and delivery comments:

Dealing with ABT is always a positive experience. Pump was in stock, which is NICE if you need work performed on the same day - Everyone else, the pump needs to be shipped. and if you are buying the Battery - nobody wants to ship that. Can't Lose to try this model out if you live in Chicago-Land Area
