I am currently thinking about adding a second pump as a back up to my primary back up sump pump in case the main one goes bad. My plumber is pushing me to Pro Series pump which I don't have any issues with. I do have a all house generator with auto transfer. My questions are as follows:
1. Is battery back up on the 2nd pump an overkill and waste of money since the batteries need replacement and probably won't be needed?
2. Which sump pumps do you guys recommend? Again,he is pushing me to Pro Series 2400 with maintenance free battery which seems to cost arm and leg
