The Zoeller 105-001 Automatic Drain Pump System is a self-contained wastewater removal solution that includes a submersible sump pump, basin, and integrated check valve. It is engineered to handle wastewater from sinks, dishwashers, washing machines, ice makers, and similar appliances where gravity drainage is not possible.

At the heart of the system is a reliable submersible pump designed to move wastewater efficiently while resisting clogs. The compact basin allows the system to fit into tight spaces, including under sinks or inside base cabinets, making it especially useful for retrofits and renovations.

Key Specifications

Design and Construction

The Zoeller 105-001 system is built with durability and practicality in mind. Each component is designed to withstand regular exposure to wastewater while maintaining reliable performance over time.

Cast Iron Pump Housing

The submersible pump within the system features a cast iron housing. Cast iron is widely regarded as one of the most durable materials for pump construction, offering excellent resistance to wear and thermal stress. It also helps dissipate heat efficiently, protecting the motor during frequent or extended operation.

Corrosion-Resistant Basin

The basin is engineered to resist corrosion from wastewater and household chemicals. Its compact footprint allows it to fit easily into confined spaces, such as under utility sinks or inside cabinets, without sacrificing capacity or performance.

Integrated Check Valve

An included check valve prevents discharged water from flowing back into the basin once pumping stops. This feature is critical for maintaining system efficiency and preventing unnecessary cycling, which can shorten pump life.

Pump Performance and Capability

Performance is a central consideration when selecting a drain pump system, and the Zoeller 105-001 is designed to deliver dependable results for residential wastewater applications.

Flow Rate and Lifting Ability

With a maximum flow rate of 43 gallons per minute, the pump is capable of handling wastewater from multiple household sources. This capacity is well-suited for sinks, washing machines, and dishwashers operating under normal residential conditions.

Solid-Handling Vortex Impeller

The non-clogging vortex impeller is designed to pass solids up to ½ inch in diameter. This allows the system to handle common debris such as laundry lint, small food particles, and minor sediment without frequent blockages. The vortex action reduces direct contact between solids and the impeller, minimizing wear and maintenance needs.

Reliable Automatic Operation

The system operates automatically, activating when wastewater enters the basin and reaches a set level. Once the water is pumped out, the system shuts off without requiring manual intervention. This automatic functionality ensures consistent performance and peace of mind.

Installation Flexibility

One of the strongest advantages of the Zoeller 105-001 Automatic Drain Pump System is its ease of installation.

No Concrete Cutting Required

The system is specifically designed to be installed without breaking concrete floors. This makes it ideal for finished basements or areas where invasive construction would be costly or impractical.

Compact Footprint for Tight Spaces

With a basin footprint of approximately 11¾ inches by 12½ inches, the system fits comfortably under sinks, in base cabinets, or in small utility rooms. This compact design expands the range of possible installation locations.

Compatible with Multiple Fixtures

The system can accommodate wastewater from a variety of fixtures and appliances, including:

• Utility sinks
• Wet bars
• Laundry tubs and washing machines
• Dishwashers
• Ice machines

This versatility makes it a practical choice for both residential renovations and new installations.

Noise Level and Daily Operation

Noise is an important factor, especially when installing a pump system in living areas or near frequently used spaces.

The Zoeller 105-001 operates with a steady, controlled sound level typical of submersible pumps. The cast iron housing helps dampen vibration, resulting in quieter operation compared to lightweight plastic pumps. While not silent, the system’s noise profile is generally unobtrusive and suitable for residential environments.

Reliability and Longevity

Zoeller products are known for their long service life, and the 105-001 system is no exception.

Factory Testing

Each system is factory-tested before shipment to ensure proper operation. This reduces the likelihood of defects and provides confidence in out-of-the-box performance.

Durable Internal Components

The use of cast iron, corrosion-resistant materials, and a proven impeller design contributes to the system’s durability. These features help the pump withstand frequent cycling and exposure to wastewater over many years.

Warranty Coverage

The included 3-year limited manufacturer warranty reflects the brand’s confidence in the system’s reliability and construction quality.

Safety and Maintenance Considerations

Proper wastewater management requires a system that operates safely and predictably.

Backflow Prevention

The built-in check valve plays a key role in preventing backflow, protecting connected fixtures and appliances from wastewater return.

Reduced Maintenance Needs

Thanks to its non-clogging impeller and solid-handling capability, the system requires minimal routine maintenance. Periodic inspection and cleaning of the basin are generally sufficient to keep the system operating smoothly.

Electrical Safety

Operating on standard 115V household power, the system integrates easily into existing electrical setups. Its submersible design ensures that critical electrical components are well-protected during operation.
