A kitchen faucet with a pull out spout is a wonderful feature. You don’t have the space taken up with a separate sprayer on the side, so these types of faucets can be mounted through a single hole which gives a very clean finish. The pull out spout is connected to a hose which is typically a beefy hose. It is braided or metal and is heavier than a vinyl hose.
When you pull the spout out of the faucet, it should retract back into the faucet when you are done with it. Sometimes they don’t.
The hose attaches to both the spout and the body of the faucet, and its job is to simply transport water. The hose loops down into the sink cabinet and back up to the faucet body. There should be a small weight attached to the hose to help pull the hose back down once you release the spout.
Make sure that the hose isn’t tangled up in the drain piping, as obviously you don’t want it weaving in and out of the pipes. Make sure the hose has a weight on the side of the loop that connects to the spout. If the weight is on the rear side of the loop, it will not help the hose retract. The weight is usually held on with a few screws that sandwich the hose in the middle.
