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.
