Here you go:
Main 1/2hp Pump
I initially had a Zoeller main pump which lasted for about 8 years until the "built-in" float switch died. I could have bought a new switch for it but the pump itself was old and I didn't want to risk it. I read reviews for the new Zoellers, Rigids, and Waynes and decided on the Wayne pump.
Backup Unit
I originally had a Watchdog unit which was 7 yrs old... I went with the Wayne backup based off of Amazon reviews when compared to others. The system includes a great backup pump compared to the crappy Watchdog unit.
Battery
Sorry, the battery was $139 shipped (not $100 as I mentioned). It's a sealed battery as well = no maintenance.
High Water Alarm I bought this inexpensive water sensor which comes with a ~6ft wire sensor
Check Valve: I also stayed away from the metal check valves because my old Zoeller check valve literally rusted apart from what I guess was from the humidity (my sump pump is located in a narrow closet). I went with a fully plastic/rubber one that my house flipping friend got from a plumbing supply store. I have the battery unit outside the closet because of this humidity build up.
Question
Which dedicated float switch are you using? One with a "rod"? Do you plan on using zip ties to hold the switch in the up/on position on your new pump?
Let me know if you have any questions. Good luck.
Thanks for the update! The discharge pipe is 1.5 inches, pit is about 22 inches deep, 18 inches in diameter. The current pump has worked fine for ~10 years now, but the power outage ruined that streak. I just figured since the 3/4 was essentially the same price as the comparable 1/2 I would go with that, didn't realize the other factors to consider that you mentioned.

I'm now debating on whether to go with a battery backup combo unit or water powered backup. Someone else recommended the Wayne WSS30V 1/2 HP Combination System which seems like it may be the perfect replacement. Looks like it recommends a 75Ah deep cycle battery. The one from Wayne is $270, but I found this Duracell Ultra Deep Cycle Battery for 12V Sump Pump for about ~$100. Would this be sufficient to use? That would put the system at about $550.
​
The other option would be to get a solo 1/2 HP pump like this Wayne CDU800 and Liberty Pumps SJ10 water powered backup. Comes out to about $350, but that doesn't count for having a plumber install the Liberty, and I have no idea what that would roughly cost, maybe you would know?

I think these are my two best options, just unsure on which route to go.
