To drain the water that is in the pipe or spout..
An aerator is on the end of your kitchen or bathroom faucet spout that unscrews and holds the screen and/or water saver.
Possibly unscrew your aerator at the end of the spout and see if the screen is clogged. Blow it out and rescrew the aerator on. If that isn't the problem, sometimes things get caught in the spout. Unscrew the spout and turn the water on. If there is water coming from there and not out the spout when it is hooked up, the spout is plugged. If no water coming out when the spout is off, rehook spout and change cartridges or stems in the faucet AFTER shutting the water off. Depends on the brand of faucet, check the instructions for the brand and model. Also your kitchen dishwasher and sinks are run on seperate valves. The dishwasher valve is usually under the sinks (causing the water to go to the dishwasher first) the valve that was installed for the sink (before the dishwasher) may be bad too.
The screen in the end of the spout is probably clogged.
A copper kitchen faucet offers more fresh water compared to the stainless steel faucet. The copper kitchen faucet also has more powerful water energy and valves.
The faucet itself does not use any water. The rate at which the water leaves the faucet is dependent on the make of the faucet.
Maybe the kitchen is further away and on smaller pipe.
Check to see if your aerator screen is plugged at the end of the spout. Unscrew it and blow it out, screw it back on.
Single and two handled faucets are different in the exact mechanism but the overall process is the same. Inside of the faucet there is a valve that diverts water from the main spout to the sprayer. Squeezing the sprayer handle opens its valve, releases pressure in the faucet, and diverts water to the sprayer.It sounds like this internal valve is jammed or broken.Call the manufacturer. I had this problem in the kitchen and Moen (the maker) provided directions on how to fix it. They can also direct you to a source for the parts.Visit a plumbing supply store. If you go during the less busy times of the day (late morning before lunch for example) they will often take the time to work with you.Replace the faucet.
When you took the aerator off the spout, did you run the water to see if it was full pressure? If it isn't full pressure with the aerator off, sometimes stuff gets plugged in the spout itself. Sometimes you can stick a wire down it and get rid of it.
Yes it is .
Well a faucet is "A device for regulating the flow of a liquid from a reservoir such as a pipe or drum". In most cases its the neck that is on top of a cink that that water flow out of. If you need any further answers for What is a Faucet? Try Google, that site will save your life.
