I have a small store and the water pressure is normally 40psi, my question is is this city water supply pressure suppose to sustain 40psi continulously?
or it could be fructulated depending on water usage?
IOW, water supply city line's pressure is 40psi, then this 40psi should be same all the time? or it can be lower pressure when people use water?
