I ended up going with:

Wayne CDU980E 3/4 HP Submersible Sump Pump

I've always ran 1/2 HP pump but my piping runs probably 100 feet to the curb, so I'm thinking the ling run might be killing the smaller hp pumps?

I think the 3/4 hp pump also has a higher amp draw so I hope its a 20amp outlet near the pump......I should have checked

Hopefully it will be here in 3 days

A bigger pump will try to move more water, faster. If your outlet piping is sized for the current 1/2 hp pump, you may need to increase it for the bigger pump.

The length of the run shouldn’t matter as much as the rise. Ideally, that 100’ of pipe is running downhill, not contributing to how far the pump has to lift the water.

Larger pits also can use higher HP pumps from what i have read

Mine is 18" in diameter and 24" deep

1/2 hp was suggested on pits under 12" in diameter

At the day job, we use 1/2 hp sump pumps and ones which can pass 1/2” solids.

We also require pumps that use a separate piggy back float. You can unplug the float and plug the pump direct to force it to run.
