TL;DR
A supply riser is a vertical run of pressurized water piping, either the distribution main that carries water up between floors of a building or, at a fixture, the short tube rising from the shutoff valve to a faucet or toilet tank. Fixture versions are flexible braided stainless, corrugated copper, or rigid chrome tube, typically 3/8 inch compression to the stop.

Fixture versions are flexible braided stainless, corrugated copper, or rigid chrome tube, typically 3/8 inch compression to the stop. In multistory plumbing, the vertical mains are sized to keep pressure usable at the highest fixtures.
