Will 10psi make a difference?

[mikeri]

Currently I'm only getting 35psi on my water line, the city measured at the street and said they had 45psi.

Would 10psi be a noticeable difference?

A consistent 10 psi difference at the shower would probably not be noticeable IMO. Pulsing would be noticeable.

Get a garden hose thread pressure gauge. It can go on an outside spigot, a laundry tap, or the drain on the water heater. When you are not using water, the pressure you measure will be the same as at the street after compensating for altitude differences.

Watch the pressure gauge, or take a movie of it, while you turn the shower on and off. That will measure the drop with use. Flush a toilet during the shower. That will tell another aspect.

Under what conditions are you measuring?

If the measurements are under no flow conditions, and the city has 45 psi at the street, but you measure 35 psi somewhere on your property, then barring measurement error the only possible explanation I'm aware of is that you are measuring at a point 23 feet higher than the city. You lose one psi per 2.3 feet of elevation, and there's no way around that.

At 35/45 PSI, yes. At higher PSI, not so much.
Anyway, it is not about the static water pressure but rather what the pressure drops to under volume. Is there an elevation change between the street and where you took the measurement? The formula for elevation loss is .43 PSI per foot.
