I don't know what brand pump you have but I would think at 10' it would be somewhere in the 3,500 to 4,000 range

So you are saying a 3170 pump will push 4000 at 10 ft I think you are confused

Why would I be confused if you lower the head height it would have to pump more water at 10' then it would at 15' plus I said it could be less like 3500 your already pushing 3100 at 15' the higher the head the less it pushes the lower the head the more it pushes as an example my pump at 3' gives me 1225 at 6' it gives me 1080.

It's the length of pipe that also plays a part

Well yes if it doesn't go straight up that would also effect the output

If it goes up at all the output will drop a lot more than going down

Also pumps are rated with no pipe and normally have different pipe size connectors so unless you use the largest size pipe you will lose flow right out of the box
