if its a bladder type tank, it will need to be replaced
The pressure tank is likely "water logged". It has lost the air inside the pressure tank.
If water doesn't go into the pressure tank you will not have water pressure.
if your water tank is water logged the pump will kick on almost immediatly when the water tap is opened, and will kick off shortly after it is closed. Water cannot be compressed. The air inside the tank allows the pump to "catch up" and shut off while the water is in use, and allows for a steady flow of water at similar pressures.
If on a well, check filter coming into house. It will drop pressure if clogged really badly. Change filter, also small blue bladder tank may be bad. Tube inside tank busted. If tank is bad you will need to replace bladder tank. When this rubber tube inside tank burst it causes tank to fill completely fill with water and becomes water logged. The last thing it could be but unlikely is foot valve going bad in well.
residual air pressure in the tank, and the pressure switch settings
with a pressure tank and pressure switch
If you mean a well tank, the water is forced in by the pump. The residual air pressure pushes the water out to the faucets.
The water pressure depends on the residual air pressure in the tank. Normally it should be between 30 -50-psi. Tank air pressure is important, it should be about 27-29 when water is nearly empty.
Your holding tank is "water logged". There is an air bladder in the tank that requires a specific pressure (dependant on the tank size). Some possible causes are a loss of air in the air bladder (just like a tire looses air over time), or the bladder has a tear or hole in it.
Water bladder tanks are tanks which contain a rubber bladder that is filled with either water or air. The majority of water bladder tanks have water-filled bladders. When a water faucet is turned on or a toilet is flushed, the water is piped in from the water tank. As the water pressure and air pressure get low, the contacts on the pressure switch click together. The pressure switch sends an electrical current to the water pump which causes the water pump to kick on and pipe water back into the water bladder tank. The amount of time it takes for the pressure switch to click on depends upon the size of the water bladder tank. The larger the water bladder tank, the longer it will be before the pressure switch starts to deliver electrical current to the water pump.

No. Nothing to do with it. Much more likely there is an air leak between pump and pressure tank, or pressure tank needs a new aircharge.
Static or pressurized tank?
