Wayne WSS30VN Sump Pump Combo vs Liberty 441 Battery Backup Sump Pump

Both are preassembled indoor sump systems with a 12V battery backup, a 3-year warranty and a float switch. The Wayne WSS30VN pairs a 1/2 HP primary pump with an 85 GPM max flow and a 46 lb assembled unit tested to 1 million cycles. The Liberty 441 is a lighter, more compact system with a 5-stage 10A charger and a mercury-free switch, offered in 1/3 or 1/2 HP. Buy the Wayne for maximum primary flow and a proven cycle-tested pump. Buy the Liberty if you want a smaller, lighter unit with smarter charging and a mercury-free switch.

• Choose the Wayne WSS30VN if you want the higher-flow 1/2 HP primary pump and a drop-in combo that fits a 16-inch or larger basin.
• Choose the Liberty 441 if you want a compact, lighter system with a 5-stage charger and a mercury-free switch, in 1/3 or 1/2 HP.
