This may or may not be interested for some: I did some playing with the hoses. Most of you prob already knew the answer but I had to learn the hard way (so maybe I’ll remember now) and maybe this could help someone else. I should’ve filled a gallon jug but I was in a rush so grabbed a watering can that was leaking and it was dark and headlight not working the greatest but here r my rough numbers for anyone who might be interested.
28 sec to fill watering can-hose with smaller hose attachments
37 sec- syphoned hose now
12 sec-current situation with the one hose w pump
7 sec hose straight from pool/pump without added hose w hose attachment= 8.6/min (couldn’t leave this scenario since it didn’t reach the street).
So, currently I have a hose outputting 12sec to fill the can and 28 sec to fill the can.
60/12=5 can/min
60/28=2.14 can/min
The one that outputted 7 sec to fill the can would have produced 8.6 cans/minute if I’m doing the math right, so if I would’ve kept the original hose (which is better for this I think than the one that is producing 7 sec/can) it would likely have emptied faster.
I’ll leave it at is as I have some unavailable time in the morning where I can’t be around taking care of this so I’ll wake up in a few hrs and see where it’s at and pull a hose out to make it go slower or if it’s too slow tomorrow I’ll go back to the original hose with the pump…
Now I know, hoses with kinks, curly hoses, I’m not sure about stretchy hoses, and hoses with nozzles on them that confine the amount of water that can come out can be significantly slower. Hence, I made the mistake by listening to the harbor freight guy didn’t I? In the end, should I have bought the blue pool hose as far as speed in concerned? I’d be curious if that would have allowed the full capacity of the 1600/gallon per hr. How would I have attached it to a hose attachment on the pump?
I’m not sure how those pumps work but seems like it’s sucking water out of the bottom and if it were to suck air I imagine it would burn up? I’ll want to plan things so that I’m around for the last part of the pool being emptied.

That's interesting. More factors to keep in mind. So I won't have to wake up at 2am either way to start the fill process. Good. I was wondering about putting the hose over the bottom rail of the pool fence or under where it'd be more of an angle after coming up and over the pool edge so I guess there's much to keep in mind! I think the pump I wanted was 2 HP but the guy at Harbor Freight said that one had a disclaimer to not use it in pools so I figured I wouldn't risk it. We'll see how this goes! I wonder what HP the ones from HD are?

The pumps flow rate is calculated with very little "head". Lifting water out of the pool will slow the flow rate as the height from the water surface to ground level increases. It's a common mistake to overestimate the flow rate when draining from a sump or pool in this case. Pumps also have a maximum lift capability at which point they will stop lifting water altogether. A sump pump with a five horsepower motor is what you need to make short work of the drain.
