Exacly I know it's hard to understand when a french like me try to learn it to you but it is part of physic.

1/4 inch pipe 10 foot heigh head will have the exact same head or bottom pressure than a 10 mile wide pipe by 10 foot height. Your pump impeler is inside the water so it dont see the ouside weight. In fact it will be a lot easy for the pump to use the 10 mille pipe as it will have absolutly no restriction so you will have more flow than that 1/4 pipe
