Nothing like a roll of glueable flex PVC on the truck and reinforced clear "hose" rated at 150psi to make life very easy. Also, or, use 1" flex water heater connectors, SS wrapped in the hole and at the tank. You trust them in all fixtures of your house, so why not in a pumphouse? Also, I got 100+ copper flex water heater connectors from gov surplus for a few dimes, and I use them everywhere 3/4 stuff is useable.

Never break in a freeze because of its corrugations, and instant unions... Then you have PVC slip repair couplings, which slide up and down as needed.
Had to replace 400' of unfindable 1.25" PVC pipe under my drive way up a mountainside. Isolated one leak and bypassed it. Then another in 2 days. Kept pump running FULL time - and it put out 25 GPM plus. Not a spot of water anywhere on the hillsides or surface - go figure. Did it when I was younger and poorer, and hadnt planned on several earthquakes. Replaced with 160 poly. Seems like that takes any abuse.
Then there is the old swing joint made with 2 street el's.
