7. Pump Age and Regular Wear
A sewage grinder pump doesn’t last forever. Depending on utilization, maintenance, pump quality, and set up conditions, the unit could finally wear out. Older pumps are more likely to experience motor problems, seal failure, reduced grinding ability, and lower pumping efficiency.
