Oh really? The main outside my house is at 11bar pressure (static, due
to hill) and immediately downstream of my stopcock, and in the same
access space, is an adjustable regulator set to 4bar

An adjustable regulator is not the same as a stop tap.

No. Which is why I said "at" the stop tap rather than regulated by it.
