More plumbing questions

I would use the 1" as the main drain and the 3/4" as the emergency drain.
Not sure what the pump is or how much head loss you are looking at but the return line may need a valve on it.

I was thinking the opposite. Let the 3/4" be the full siphon, possibly without a valve, and let the bigger pipe have what's left. Seems safer to me. That way if(when) a blockage happens, there is a unrestricted 1"pipe to take over. Compared to something clogging a restricted 1" main and only having a 3/4" emergency pipe. Wouldn't matter with that return pump, but seems more ideal

i have a locline with 2 "arms" and 2 regular nozzles, i forgot the name but its like a cone

For a first time plumbing job and going with a over the top return I would use flexable tubing and a return nozzle similar to what a canister filter return would be.

I already have loc line if thats what your saying, but should i just get 4ft of braided and a spigot x barb to do the over the back ?

It seems like your message is bugged. I already have a 10ft piece of 3/4" so I would perfer to use it. Do you think that would be okay?

Drains with pvc.
Return can be flexible tubing. Any kind of braided line that fits the output of the pump.
