Zoeller 507 Aquanot Fit Battery Backup Sump Pump System vs Wayne WSS30V Sump Pump System

Buy the Wayne WSS30V if you want one box that covers both jobs: it pairs a 1/2 HP cast iron primary pump with a 12 V backup, so a power outage doesn't leave you with a dead pit. Buy the Zoeller 507 if you already have a working primary pump and want a well-built backup with a smart control box, alarm and float switch. The Wayne's pre-assembled, preset setup is the easier install; the Zoeller's separate control box and float give you more visible status and a longer stated warranty.

• Choose the Zoeller 507 if you already have a reliable primary pump and want a backup with a solid-state control box, alarm indicators and a variable-level float switch.
• Choose the Wayne WSS30V if you are replacing or starting fresh and want the primary pump and battery backup in one pre-assembled, preset system.
