Product Questions
Answered by Jim, the Sump Pump Expert
Does this back up pump have similar specs to the Main 257 pump?

I'm confused about battery specification for this. Your site says not to use AGM battery, but Liberty's site says you can. Why the difference in advice? Thank you.

If the 120 v pump can't keep up it sounds as if the battery backup pump will kick in---but the units share a common pipe so how can you add water /flow to an already maxed out pipe?? Would this not just increase head pressure on the battery pump causing it to work even harder????
