Product Questions Answered by Jim, the Sump Pump Expert
Do we get the primary pump too?

Just FYI - I've seen a lot of questions about this so I thought I would pass on this information. The 5-stage charger in Liberty Pumps 441 system is manufactured by Diversified Power International. I checked with them and maintenance free flooded (wet) lead acid batteries will work with the charger. So, the marine batteries (Group size 24 or 27) that you can buy at Walmart, Sears, auto parts stores, etc will work fine

I have a new EverStart 27DC Battery (Walmart) that I want to use with the Liberty Pumps 411 backup pump. It is considered a Maintenance free deep cycle battery. Will this battery work properly with the 411 charging system?

Just bought an older home and was looking to purchase a new sewer pump,leaning towards the Liberty PRG101A. Would it be a good idea to also put a battery back up unit in with it?

Looking down the road, if and when the pump fails / wears out, would I be able to replace it or do I need to replace the entire unit? Hence, would I be able to use the power inverter or controller with other pumps? Thanks.

Hi, Jim - We lost our finished basement during the Aug. 11 hurricane - power failed for 28 hours and we collected 16 inches of water in the basement destroying everything. Need a good backup sump pump and would like a battery-operated pump, but am considering a water-powered pump. Can you tell me which brand/model would be your choice. We are in a wet area, and our current Liberty 1/3 hp pump works 24/7. Can't refinish the basement until we get a backup pump as we could easily flood out again when the power fails again. Very troublesome! Thank you! Lois
