Why do sewage grinder pumps keep failing?

Sewage grinder pumps are failing repeatedly within a few years because replacement contractors offer no diagnostics, leaving homeowners to face mounting costs and recurring breakdowns. This cycle is compounded by confusion over sump basin design and whether basin walls require custom or standard drainage holes.

“Then the sump pump went out. I bailed the water out of the sump well basin (which is a plastic insert into the ground), cleaned it up and replaced the pump.”source ↗

“This can't be right, can it? When I Google, there's a variety of different basind. Some with an array of smaller holes, some with big holes and some like mine with no holes.”source ↗

“My assumption would be that with the no-hole ones you'd add your own? If so, how many should their be, and size? And if there are supposed to be holes, could this be why water show up where the concrete meets the dirt?”source ↗
