I'm building a hydraulic ram pump, pretty much have it done. It uses a 1 and 1/4 inch drive pipe and a 3/4 inch delivery pipe. I plan to use irrigation tubing for the delivery. Thing is 500 feet of 3/4 inch delivery tube costs $200 but 500 feet of 3/8 inch costs $40.

Is there any reason i can't use smaller tubing?

PVC is going to burst long term you need metal. Water hammer is a bitch.

The particular design i'm using has a proven 10+ year life span, it's been around a while. All the parts that take the force from the water hammer cycle are metal so no problem there: https://www.landtohouse.com/wp-content/uploads/2015/02/lth-ram-pump-v-1-2.pdf

try the smaller tubing and if it doesn't work, then you're only out $40
