Pros and cons

Pros

Vertical float
10,980 gph
3-year warranty

Cons

18 ft head limit
Plumber install
Higher price

Limitations to weigh

Sewage and grinder installations usually need a licensed plumber and a sealed, vented basin to meet code.
Fit a check valve on the discharge so water in the pipe doesn't fall back into the pit after each cycle.
Maximum head is where flow drops to zero; at your lift the pump moves less than its maximum flow. Size it with the sizing calculator.
