Power steering pump question

George Jets said
Don't turn it full lock, it hard on the pump over pressuring it when it hits the stop.

It's not going to turn any farther anyway.

It does it during regular driving like if your pulling out of a parking lot or backing into the driveway. I'm not doing it on purpose. The only way I could replicate it while parked was turning it lock to lock.
