Can I claim an easement by prescription for my drainage pipe that has been on my neighbor's land for years?

I have a drainage pipe for my pool that has been partially over the border line with my adjacent neighbor's property for over 20 years and nobody ever said a word about to me. The new owner is now trying to force me to dig it up and move it 100% to my property. Do I have any chance of successfully claiming an easement by prescription?
