What's the typical mains water pressure in a house with modern plumbing?
The reason I ask is that where the water comes in, there's what looks like a
pressure regulator valve with a pressure guage on it. (I assume it's also
the isolator for the water into the house as I can't find any other stopcock
type valves anywhere.
I'm used to older house where the isolation was done by a brass valve with a
tap type handle on the top - This valve has a black cylindrical handle about
2.5 inch diameter. It does alter the pressure when turned but I haven't
turned it right down to see if it's the cut-off for the house as it seems to
turn for ages.
Anyway, the pressure guage reads 3 bar - Is this normal?
It's a new house (well, to me anyway - It's nearly 4 years old) and I just
wanted to check.
