Sometimes a high pitched noise will begin to come from your kitchen faucet. The noise is sometimes accompanied by a lack in water pressure. If you notice such a noise, you will probably want to deal with it after a day or two because the noise will become unbearable. There are usually only three reasons for the high pitched noise to occur in the first place.
A Kink in the Water Line
If your water line is kinked it will definitely cause a drop in the water pressure. It can also cause the high, squeaky sound. Un-kinking the line will usually rectify the situation.
A Water Conservation Washer
Many of the new faucets will have a small washer fit on the water line that will restrict the water supply in an effort to conserve water. The restriction caused by this small washer can also cause this high pitched, squeaking sound. The washer can be removed with a pair of needle nose pliers.
Sediment in the Line
Mineral content can build up in the water lines leading to your faucet. Bits of the hardened minerals can break off into the water line and stop the water from flowing freely. The restriction in the flow of water can cause the annoying, high pitched sound. Draining the line can remove the sediment and stop the squeaking.
