Zoeller 805-0001 Residential Grinder Pump 3/4 Hp 115V

Product Description

The ZOELLER 805-0001 is a residential automatic grinder pump designed for below-grade sewage ejection applications where standard ejector pumps cannot reliably handle the waste load. Rated at 3/4 horsepower and operating on 115 volts at 9 amps, this cast iron pump grinds and pumps the full range of household waste materials, including so-called flushable products, that would clog or overwork a conventional ejector. With a shutoff head of 45 feet and a flow rate of 42 GPM at 5 feet of head, it delivers the performance required for a complete household installation. The automatic float-controlled operation eliminates manual intervention during normal service.

This pump is built for difficult residential plumbing applications where waste must be lifted or pumped horizontally to reach a gravity sewer or septic system. It is a practical solution in basement bathrooms, below-grade laundry rooms, and full-household below-sewer-line plumbing configurations. The all cast iron construction is appropriate for the abrasive and corrosive environment of a sewage basin. Licensed plumbers typically specify this unit when a standard sewage ejector has failed to keep up with household demand or when flushable-product clogging is a recurring problem.

Key Features

• 15-foot power cord provides installation flexibility in standard basin depths

Compatibility

Designed as an OEM-style automatic grinder pump for residential sewage and effluent systems requiring below-grade waste grinding and ejection. Consult basin dimensions and discharge plumbing configuration before installation to confirm fitment.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off electrical power at the breaker and cap or isolate the discharge line before servicing or replacing the unit. The basin must be properly sized to accommodate the pump body and allow float travel for automatic operation. Do not operate the pump dry, and verify discharge piping is free of blockages before commissioning.
