Stupid Question Upstream Downstream?

[Plumber69]

If it said. Install a solenoid valve upstream from the gas regulator. Does it go before or after the regulator.

Before.

I keep getting different answers from different people.

downstream is the direction a stream is flowing.

So upstream from the regulator would be before the regulator's intake

Suppose I had a dam on a river.

The water would come from upstream, and go downstream.

Also, consider the expression "swimming upstream".
