I called the water district where I live. he offered to come out and "check the pressure" with their own meter, but he said that unless there was some problem with the pipes, the pressure everywhere was 45 PSI.
Maybe there would be some variation with hills and valleys, but I live right near sea level.
At 45 PSI, a garden "jet" sprayer will shoot most of the way across my small front yard, but at 30 PSI, it goes half as far.
I thought that buying a pressure gauge would be very expensive, but actually they don't look too bad! You would have to be sure to get something that fits garden hose conenctors.
