Buying Guide
What to consider when choosing a grinder sewer pump system:
- Flow rate and head height: Match the pump’s GPH rating and lift capability to your installation height and drainage distance.
- Discharge size and compatibility: Ensure 2″ or 2″ NPT discharge aligns with your piping and hose adapters.
- Grinding capability: A robust grinder prevents clogs by handling solids and debris typical of your wastewater.
- Power source and installation: Decide between portable, cordless models (like the Camco) and hard-wired or plug-in submersible pumps based on location and access.
- Auto vs. manual operation: Float switches improve reliability by starting/stopping pumps based on water level, reducing dry-running risk.
- Durability and materials: Cast iron and stainless steel housings extend lifespan in harsh effluent environments.
- Maintenance and safety: Look for thermal protection, IP ratings, and clear lifting/handling guidance to prevent damage during service.
FAQ
- Can these pumps handle solids larger than 2 inches?

Most grinders are designed to handle common solids but check the blade design and 2″ discharge specs; some products warn against very large debris.
Auto operation with a float switch helps prevent overflows and dry-running in unattended basements; it is highly recommended for consistent performance.
Cordless models offer portability and easier setup but may have limited run time depending on battery capacity; for stationary basements, wired options are typically more reliable long-term.
Inspect for wear on grinding components, check seals for leaks, ensure the float switch operates freely, and keep the inlet clear of obstructions.
Many grinders are not intended for septic tanks; follow each product’s guidance to avoid improper use and potential system damage.
Non-septic basement or well installations often require electrical and plumbing expertise. If unsure, consult a licensed professional for safe, code-compliant setup.
