We have a 3/4" meter / water supply line to our house. How much pressure difference should I expect between when no water is running and (say) one cold tap is open full? I assume flow rate is about 1gpm.
The reason I ask is that our pressure regulator was replaced recently, but we are still seeing noticable pressure drops. Input pressure is close to 100psi (I haven't measure it exactly) so I would expect that setting it to 60psi there should be enough source pressure to sustain a fairly constant 60psi even with some water running. How far below 60psi should I expect to see?
