Hello,

I have a house in a neighbourhood with very high water pressure 100+psi.
A pressure reducing valve was installed and appears to work once there is water flowing,
this was tested at various settings and looking at the gauge.

However when there is no water used in the house/flowing, the pressure rises to the 100+psi.
Are PRV valves supposed to work like this or is there a problem with this valve ?

Thanks,

L
