Wayne WSS30VN Sump Pump Combo vs Pro Series PHCC-2400 Battery Backup Sump Pump

These are different kinds of product. The Wayne WSS30VN is a matched combo: a 1/2 HP primary pump plus a 12V backup in one preassembled unit, rated 85 GPM max and tested to 1 million cycles, with a 3-year warranty. The Pro Series PHCC-2400 is a backup-only pump that bolts onto a primary pump you already own, rated 2,400 GPH at 10 ft of head with continuous duty and an alarm. Buy the Wayne if you are replacing the whole pit. Buy the Pro Series if your primary pump is fine and you only want power-outage protection.

• Choose the Wayne if you want a complete drop-in primary-plus-backup system for a 16-inch or larger basin and would rather not match parts yourself.
• Choose the Pro Series if you already have a working primary pump and want to add battery backup with continuous duty and an alarm.
