Answers:    if your boiler only requires 1-1.5 dowel don't worry roughly speaking it. Your mains pressure simply will NOT be below 1 Bar (that is the pressure that the atmosphere exerts on an object at ocean level).
60 PSI is about 4.15 Bar and my Vaillant Combi switches itself stale after 3.2 bar. 30 Psi from the D (2 bar) is plenty.

A pump is required where the system resistance prevents the river from going the distance, not to increase an inadequate supply. If theres individual so much water arriving at your stopcock, you can't increase it next to a pump.

What do think get the water to your house, a pump!
adjectives you will be doing is amping the push on the water and bloodbath your neighbors pressure.
