Zoeller 267 Sewage Pump Review: Performance, Installation, and Longevity
In-depth, balanced review of the Zoeller 267 sewage pump for residential basements, covering design, installation, maintenance, performance, and how it stacks up against alternatives.

Definition: The Zoeller 267 sewage pump is a compact, electric submersible unit designed for residential sewage ejector pits. It automates wastewater transfer with an integral float switch, moving effluent from below-ground fixtures to the building’s sewer line. Built for durability, it relies on a robust housing and corrosion-resistant components to withstand typical basement conditions and routine maintenance.
What is the Zoeller 267 Sewage Pump?
According to Sump Pump Check, the Zoeller 267 is a compact, electric submersible unit designed for residential sewage ejector pits. It automates wastewater transfer with an integral float switch, moving effluent from below-ground fixtures to the building’s sewer line. Built for durability, it relies on a robust housing and corrosion-resistant components to withstand typical basement conditions and routine maintenance.
Design and Build Quality
The Zoeller 267 uses a heavy-duty enclosure designed to resist moisture and chemical exposure found in basement pits. Its sealed motor housing helps protect electrical components from humidity, while the impeller and seal assembly are chosen for reliability with solid waste and variable flows. A standard float switch provides automatic on/off control, reducing the need for manual intervention.
Installation Considerations
Installing a Zoeller 267 requires a properly sized ejector pit, a discharge line routed to the sewer or septic system, and a check valve to prevent backflow. Local codes may dictate venting, gasket standards, and electrical grounding. For DIY installers, ensure you have the right pit cover clearance, a secure power connection, and a risk assessment for gas or moisture exposure.
Performance and Testing Methodology
We evaluate the Zoeller 267 using a standardized testing protocol that mirrors typical home use: steady wastewater input from several fixtures, measurement of run time, and observation of cycling. The aim is to track how quickly the pump rises to the discharge point, how it handles varying loads, and whether coughing or stalling occurs when solids are present. Sump Pump Check's testing framework guides our conclusions.
Maintenance and Troubleshooting
Regular maintenance helps extend the life of the Zoeller 267. We recommend inspecting the float operation, cleaning the inlet screen, and checking for leaks or corrosion at least once a year. If the unit runs continuously, stalls, or fails to start, inspect the float alignment, verify power, and examine the discharge line for blockages. Keep a spare seal kit handy if you expect frequent service.
Common Issues and Fixes
Common issues include premature wear of seals, clogged intakes from toilet tissues or foreign objects, and nuisance beeping from the float switch. Fixes range from cleaning the screen and clearing the discharge line to reseating seals and checking wiring connections. If odor or backflow occurs, verify the pit is properly vented and the check valve is installed correctly.
How it Stacks Up Against Alternatives
Compared with grinder pumps, the Zoeller 267 does not macerate solids; it handles typical wastewater with a solid-strain approach suitable for properly sized pits. Submersible sump pumps offer simpler installations but may require more frequent maintenance if solids build up. For homeowners prioritizing simplicity and reliability in a standard basement ejector setup, the 267 presents a balanced choice.
Longevity, Warranty, and Spare Parts
Durability comes from a rugged housing and commonly available replacement parts. Warranty terms vary by retailer and region, but we emphasize investing in a pump with a reliable service network. Spare parts such as seals, gaskets, and impellers are typically accessible through major plumbing suppliers, ensuring minimal downtime when service is needed.
Real-World Scenarios and Best Practices
In basements with regular wastewater loads and careful pit maintenance, the Zoeller 267 can deliver predictable performance with limited fuss. For homes with infrequent use or variable wastewater input, a robust float switch and proper venting reduce nuisance cycling. Always pair the pump with a reliable backup option for power outages and keep your drainage lines clear to avoid clogs.
What's Good
- Durable cast-iron housing and robust components
- Automatic operation via built-in float switch
- Good availability of replacement parts and service
- Relatively straightforward installation in standard pits
Drawbacks
- Not designed for high-volume or commercial workloads
- Requires proper pit size, venting, and check valve to prevent odors
- May require professional installation to meet local codes in some areas
Best balanced choice for standard residential sewage ejector duties
The Zoeller 267 delivers reliable performance in typical basements with solid-pipe discharge and automatic control. While not ideal for heavy-duty or high-volume applications, it pairs with sensible maintenance and a well-installed pit to offer long-term value for most homeowners, per Sump Pump Check analysis, 2026.
FAQ
Is the Zoeller 267 suitable for all basement configurations?
In most residential basements with a typical ejector pit, the Zoeller 267 is a common choice. Suitability depends on pit size, discharge routing, and local codes. Always verify clearances and pit dimensions before purchasing.
For most standard basement pits, Zoeller 267 works well. Check your pit size and code requirements first.
What solids size can it handle?
Residential sewage pumps are designed to handle solids like toilet paper and small solids typical of household waste. Do not expect to grind or macerate large objects.
It handles typical household waste; avoid big objects.
How often should I service or replace seals and bearings?
Follow a regular maintenance schedule: inspect, clean, and test the float and seals annually or per manufacturer guidelines. Replace worn seals if you notice leaks or decreased performance.
Inspect annually; replace worn seals as needed.
DIY installation vs professional installation?
If your local code requires a professional install or if you lack plumbing experience, hire a pro. Basic installation can be doable for handy homeowners, but ensure electrical and drainage work meet code requirements.
If you're unsure about electrical or drainage work, hire a pro.
What warning signs indicate failure or impending failure?
Common indicators include frequent cycling, unusual noises, odor from the pit, failure to start, or constant running. If you notice these, stop using the system and inspect or call a professional.
Watch for cycling, noise, or odors; these mean service is needed.
How does Zoeller 267 compare to grinder pumps?
Grinder pumps macerate solids before pumping, often used where solids management is critical. The Zoeller 267 is a standard sewage pump and lacks grinding capacity, so use where solids are minimal or pits are properly screened.
Grinder pumps grind solids; Zoeller 267 does not.
Top Takeaways
- Assess your pit size and check valve placement before purchasing
- Favor models with automatic float control for hands-off operation
- Schedule annual maintenance to extend life and prevent odors
- Pair with a backup pump for power outages
