The Zoeller M267 sewage ejector pump (Waste-Mate) is used to lift wastewater from a basement bathroom or below-grade plumbing up to the main sewer line. Repair is often worth it for external issues like a failed check valve, stuck float, or a clogged discharge-especially when the motor is healthy.
Replacement becomes more attractive when the pump must be pulled and shows corrosion, seal leakage, or intermittent motor starts, because labor and hygiene considerations make repeat service costly. Use the threshold to keep spending proportional: if you're paying for pump removal plus significant parts, replacing with a new pump and fresh warranty often reduces future risk.
Also address root causes: wipes and fibrous materials can jam impellers and ruin seals, while frequent short-cycling from a small basin or float misadjustment can shorten motor life. If the pump is older and you've had multiple backups or alarms, proactive replacement can be cheaper than another emergency call.
