Water faucets need maintenance from time to time, just like anything else in the house. One thing to replace that will eliminate most faucet problems is a washer or rubber seal. They can be the cause of leaky faucets, running faucets, or whistling faucets. A number of things can cause whistling faucets, but before you call a professional, check the rubber washer or seal and the aerator. For anything else, contact a professional.

Repairing a Whistling Faucet

Step 1

Shut off the main water supply. Turn the handle in line with the water pipe. This handle can be closed by turning it with your hand. Turn the handles on the faucet in the kitchten to turn on the water. This releases pressure in the water lines.

Step 2

Replace the washer in the faucet handle assembly. To do this, remove the cap; you may have a snap-on cap or a decorative round piece. Do this by prying it up with a flat-head screwdriver cap or by unscrewing it. Use a Phillips screwdriver to remove the screw that sits below the cap.

Step 3

Remove the handle assembly, which is the handle and the assembly that sit under the handle, by unscrewing it with an adjustable wrench. Place the adjustable wrench at the base of the assembly where it attaches to the water pipe. The base of the assembly also holds the assembly in place on the sink. Unscrew it in a counterclockwise motion. Remove the screw that sits in the center on the bottom of the assembly. Pry out the washer with a flat head screwdriver. Replace the washer with an exact match. Repeat this for the handle or handles of the sink that is whistling.

Step 4

Apply plumber's putty around the threads on the faucet assembly. Screw it back into the water pipe. Place the handle back on. Screw in the top screw and place the cap back on. Repeat this for both sides.

Step 5

Look at the base of the spigot, which is the piece that water comes out of. There is a metal ring or decorative cylinder sitting there with the spigot coming out of it. Unscrew the ring or decorative cylinder. You can unscrew it with a rubber-tipped plumber's wrench or a rubber-tipped adjustable wrench. (The rubber protects the faucet from damage.) Unscrew it in a counterclockwise motion. The spigot is now no longer attached, and nothing is holding it to the water lines. It is just sitting there with a rubber washer holding it in. Gently rock the spigot back and forth. It will come right out from the water pipe.

Step 6

Locate the washer on the bottom of the spigot. Remove this with a flat head screwdriver. It will slide over the bottom of the spigot. Replace it with an exact match.

Step 7

Put the spigot back into the pipe. Screw the base back on. Turn the main water supply back on.
