I’m after some help with understanding how water pressure is less once it’s past the stop valve.
Last night I had to urgently replace our leaking mains stop valve with a gate valve which was all I had.
It’s working ok but I know how it’s made differently, so that eventually it won‘t shut off too well.
But apparently there’s another reason why you should not use a gate valve as a stop valve:
I’m reading that a gate valve is not supposed to be directly on the mains inlet because it is only meant for low pressures. That seems to infer that once past the stop valve the water has less pressure.
I’m not a plumber but either way, I don’t really understand this.
Surely regardless of how much or how little the initial stop valve restricts flow, the actual pressure is still the same anywhere else in the house (except gravity feeds) because the stop valve has only restricted the flow, and not the pressure, which is something different.

So to me, regardless of the flow, any gate valve in the house, unless it's on a gravity feed for example, must still be getting the same pressure as the stop valve.
Thanks, Dave
