Your water company guy may be right, but I would suggest exploring this. See what your neighbors have. A pressure gauge is cheap and easy to use. Household water pressure can and does vary, but 30 psi to 60 psi is considered within normal range. Could be more, but not necessary. 14 psi is really off the bottom of the chart. You have to have more pressure to get decent flow. You're getting all of the pressure available, but your problem is lack of flow. There's a problem somewhere and I suspect the water company is not giving you full information.
