Every faucet in my house performs poorly. The first thing in the
morning, they flow pretty well for a few seconds, then slow WAY down.
Some days it's the bathroom sink other days it's the tub; every day it's
the kitchen sink.
Here are the symptoms:
* Faucets flow well for three seconds or so first thing in the morning.
Debris or crud buildup (eg: rust).
[Assuming you don't have a regulator. It could be jammed
or defective if you have one.]
Contact the water company again and ask them if they'll do
Water companies have rigs that will pulse pressurize the
line, and blow out any crud.
My father water supply was suffering similar problems, but not
quite as bad. After calls to the municipal water office, he
learned that this was endemic to his area (development
only about 35 years old). But because of the number of houses,
they weren't simply going out and doing it, they were waiting
for people to complain.
They came out, zapped the line, and it worked much better
from then on.
Generally speaking, if you have a constriction problem, the static
pressure (water pressure whenn you're drawing no water) will
be the same as the water mains. It's when you start drawing
water that the pressure drops drastically.
If you have a leak, that could explain it. So could a

one of those could cause your problem. By the way, if I was your neighbor,
I would be installing a pressure regulator on my water system. Household
appliances are designed to safely work with 60 pounds pressure. Any more
than that and he's risking a failure that could result in serious water
damage to the house. And of this I speak with experience. 90 pounds
pressure caused me $3000 water damage twice before I got smart and installed
a regulator dropping the pressure to 50.
Focus on searching for a Pressure Reducing Valve.
Might look like this:
There is no reason that your pressure gauge
should read 40psi while street pressure is 100psi
unless you have a PRV.
There could be other reasons for the reduced flow,
such as restrictions mentioned, but start with the PRV.
