Chances are the pipe is being constricted somewhere in the line. However, there is also a chance there is a problem with your well pump, water tank, or well itself.

It depends on what you mean by "quickly".

If the pressure is good right away, but almost seems to "spray" out of the faucet and then after just a few seconds drops to a low but stable pressure, then a constricted pipe is most likely the problem. If it is good right away, but then quickly drops after a 30 seconds, or minute or two, it could be a pipe but is more likely something wrong with the pump, tank, or well.

it occurs in only certain places in the house, then it is most likely a partial blockage in the pipe that leads to that specific faucet(s) or the faucet itself. If it is in the entire house, then it could be a partial blockage in the main line coming to the house or something to do with the pump, tank, or well.

A constricted pipe could be caused from pipe corrosion, foreign material, a bent area of pipe, a partially closed valve, or a partially frozen pipe. If you live in a cold climate and think freezing might be affecting the constricted areas in question then this might be the first thing to check by gently thawing the affected pipe areas as you would a frozen pipe to see if the pressure returns. Corroded pipes can be replaced or possibly cleaned with the water to that area turned off.

To see if it is the pump or related equipment , you can check the pressure at the pump or right after the water leaves the pump. This can be as easy as reading the gage on your pump or attaching a gage to a nearby hose bib or as hard as cutting out a piece of the pipe and installing a pressure gage directly in the line. You will have to determine if your pump already has a gage or a nearby hose bib to easily install a gauge or if you have access to somebody with the skills to do the pipe cutting. If the gauge shows a pressure drop after you open a faucet, you know to call in someone who services well pumps. If the gauge stays the same, you know the pipe is being partially blocked somewhere down the line. If you know it is the pump or other equipment, then there could be a million things possibly wrong with it from worn parts, to leaks, to a poor electrical supply. With research, you might be able to narrow down the problem and with the right resources you might be able to fix the pump yourself but calling in the pro will get you running water much faster and you wont have to deal with a potentially very deadly shock hazard!

If water pressure from kitchen faucet is low however pressure is strong coming from sprayer What could be the problem?

The screen in the end of the spout is probably clogged.

How do you get the air out of the line after installing new faucet?

Very simple. Run each faucet until there is no more air. This usually only takes a minute or two per faucet. Remember air is lighter than water and will quickly rise, thus exiting the faucet additionally the strong flow of water out of the faucet is a huge plus.

Why do I have only one water faucet in my house with slow running hot water although the water water is pressure is strong?

Perhaps the filter screen is blocked, which you can clean and replace. This may improve the flow through that faucet.

Why flow of water decreases when someone open another tap in same building?

The water in a building has a certain pressure, depending on how high the storage tank is. One tap opening has the full pressure acting on one small area, the size of the tap. If a second tap is opening the pressure acts on a wider area, so it is not so strong.

Why is opening the windows during a tornado a myth?

The openting windows myth is based on the idea that the low pressure inside a tornado causes houses, where pressure remains high, to explode and that opening windows equalizes pressure. This does not work for several reasons: It is wind and debris in a tornado that causes damage, not the pressure difference.The pressure difference created even inside a violent tornado is a fraction of what is needed to cause significant damage.Houses are not airtight, even with the windows closed.A tornado strong enough to cause major damage will create plenty of openings and break the windows anywayIn a weak tornado or a glacing blow, opening windows exposes the interior to strong winds, which can cause damage inside as well as outside.

Why is the wind strong?

To first order, because the pressure gradient is strong.
