Stopped at all faucets? Didn't pay the water bill. If in cold climate, the line from the outside to probably the water heater has probably frozen.
The osmotic pressure. This is the pressure which would have to be applied to a solution to stop water entering if it was separated from pure water by a semipermeable membrane.
Ghosts!
pressure switch
There is no such thing as a valve cannot increase or decrease pressure IT can throttle volume or stop the flow.=One would need a pressure booster pump to increase pressure=
An angle stop is not intended to control water pressure for most applications. That being said, however, you can control the pressure with an angle stop valve (Aka angle pattern globe valve) while there is flow. As soon as the flow stops, then the pressure will equalise throughout the system. I would suggest using a PRV or pressure reducing valve. This will control water pressure under most all conditions.

Check the universal joints and balance of the driveshaft. When you are accelerating pressure is applied to these parts and if they are worn or out of balance or dented they will cause a vibration that will stop when you let off the gas.
your oil pump is bad
Salt is not the cause of high blood pressure - it is vital for regulating the blood pressure. You should NOT avoid salt. Drink more water instead - and stop drinking other beverages such as soft drinks, coffee, energy drinks, tea, etc. These drinks cause dehydration - the underlying cause of high blood pressure.
We drink water to avoid becoming dehydrated, which, in severe cases, could cause our internal organs to stop working.
If you mean "Why does the water from the supply pipe stop flowing?" it is best to check with your local water supply utility company. Maybe they are doing some maintenance work on their water distribution network?
The doctor had to apply pressure so that the patient's wound would stop bleeding. The pressure to do well on the upcoming test was almost more than she could bear. The water pressure in my city was low yesterday.
water pressure from the main or pump , side is greater that the lowest setting on the pressure valve, causing the diafram to viberate,
