Zoeller WDH820 Grinder Pump — 20′ Cord, Hardwired Switch (820-0011)
Zoeller WDH820 Grinder Pump with 20′ Cord and Hardwired Switch — Model 820-0011
The Zoeller WDH820 is a 1 HP hardwired residential grinder pump engineered for demanding sewage applications where high head and clog-resistant performance are a must. Featuring a hardened cutter mechanism and durable cast iron construction, the 820 grinds solids into fine slurry to keep wastewater flowing in systems with longer discharge runs and higher lift requirements.
Key Features
- 1 HP grinder motor ideal for heavy-duty sewage applications
- Stainless-steel cutter system reduces solids to a fine slurry to prevent clogs
- Hardwired switch configuration for direct control panel or float switch setups
- High-head performance for long discharge distances and tall vertical lift systems
- Rugged cast iron pump housing built for longevity
- Thermal overload protection for added motor safety
- USA tested and assembled 100% Factory Tested - every pump is submerged in water and tested at the factory to ensure that it performs as expected when you receive it
Best For
- Basement and below-grade sewage systems
- Installations with long pipe runs or significant elevation
- Residential grinder applications needing clog resistance
- Panel-controlled sewage system installations

Common Questions
Q: What makes a grinder pump different?
A: Grinder pumps macerate solids into fine slurry, allowing reliable pumping through smaller pipes and long distances.
Q: Is this model automatic?
A: No. The WDH820 is a hardwired model intended for control panels or external float systems.
Q: Is this suitable for basement bathrooms?
A: Yes. The WDH820 is commonly installed in residential below-grade sewage systems.
