Because your losing "volume" possibly the piping is under sized or the internal diameter was reduced by mineral deposits
If this faucet has a spray hose, turn on the faucet and open the spray hose.This will adjust the diverter in the kitchen faucet to the spray and pressureize the hose.This will allow the faucet to equilize and the sputter will stop if the spray diverter is working. It could be that the diverter part in the faucet is defective.
To drain the water that is in the pipe or spout..
A water faucet is the mechanical device fitted to the water supply pipes over bathroom and kitchen sinks. When turned on they supply water.
My guess is your garbage disposer was also replaced and they forgot to knock out the plug before connecting the disposer hose/drain It sounds like you have a vacuum breaker on the drain for the dish washer. This is probably just a coincidence but your vacuum breaker needs to be replaced or repaired. It really has nothing to do with the faucet installation.
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.
I just installed an American Standard kitchen faucet and it continues to run for a second or two after turning the handle. I called AS and they said it is because of the high arch and the location of the stop valve lower in the fixture. I think it may have more to do with this being a lower end kitchen faucet. During a bathroom remodel we installed a high arch Pegasus bathroom faucet and, while it is admittedly not at high as the kitchen faucet, it stop immediately and doesn't continue to run/drop at all. When I removed the Pegasus faucet filter at the spout, it behaves just like the kitchen faucet, so there's some sort of stop valve element at the spout of the Pegasus that isn't part of the AS faucet.
I just brought a Glacier Bay pull down ceramic kitchen faucet Model 896408. After installing it, the cold water wasn't coming out of the faucet. It turned out the problem was the coldwater supply line inside the faucet was bent & twisted. As a result, when the body of the faucet was attached, it had to be turned just a little to position it correctly, this tighted and choked the water supply line even more- which meant "no cold water." Waiting on replacement line from Glacier Bay, which, I am certain, will correct the problem.
Have you got two single faucets or a single lever faucet? It could be a pressure imbalance or it could just need maintenance
The faucet drips even when the water is turned off.
Seperate valve for outside faucet turned off, broken valve stem inside of outside faucet or handle stripped at faucet.
The water valve under the sink is turned off or has gone bad. It is possible that there is a blockage in the faucet itself. I'd start by ensuring that the water valve is turned off, and take the faucet apart and look for anything out of the ordinary.
It should have both. Verify that it has two lines to the faucet. If it does, check to see if the stop valve under the sink has been turned off. It may have been leaking and turned off instead of being repaired.
