Inner sactum oil galley plug

No, that is not what I am saying because you don't have a space in the line in your house that is charged with air to backup pressure.
And if you did when you turn off the water supply out at the street the accumulator will then push the water out and you will still have running water until the accumulator is drained.
People that have wells at their house or their Farms understand what happens if the pumps not running but you still have water in that pressure tank.

Most houses infact do have accumulators, in the form of a plugged upright pipes located close to washing machines and showers.. An accumulator is merely a "hydraulic spring" to modulate or extend pressure, and the oil filter would purge in just a few seconds, because of the valve, ... cheers..
