why does my kitchen faucet whistle

A whistling faucet not only makes people feel fidgety, it is also a sign of different problems in it. So why does my kitchen faucet make whilstling noise? In this post, we will analyze the causes of a whistling kitchen faucet from various aspects and show you how to fix a whistling faucet easily and efficiently.

The causes of whistling faucet

Residue Issues

One of the reasons for noisy kitchen faucet is the accumulation of residue. It often occurs under or around the washing machine seat. It can also accumulate in the faucet stem, which can cause kitchen faucets to whilst. If your water is hard, the tap may also have some mineral deposits. When these deposits restrict the flow of water through, a whistling sound is produced.

Pipe Problems

The whistling noise from your faucet might originate within your home’s plumbing lines. It’s also a possible problem when you’re using galvanized pipes since they tend to get a buildup of scale and rust. To confirm whether it is caused by the water pipe, you need to replace with a new water pipe, but it is obviously a hard job for average person. It is recommend to ask a plumber for help.

High water pressure

You may notice a whistling sound on more than one tap, which usually indicates that the water pressure is too high. You can test the pressure by screwing an inexpensive pressure gauge onto one of your outdoor faucets. If there are oil wells, check the pressure gauge on the pressure pump.

Ideally, the pressure should be between 50 and 60 psi. If the pressure is much higher than this value, you need to adjust the pressure regulator or reduce the cut-off pressure on the pressure pump to reduce the pressure. If you don’t know what to do, call the plumber as soon as possible before the high pressure ruptures the pipe or the fitting.

Valves problem

A noisy faucet might happen due to a dislodged or broken valve. It also happens on a wrong size of valve. To comfirm this,you need to turn off the faucet’s water supply at first.Then try accessing the valve in the kitchen faucet. Make sure to follow your manufacturer’s directions to finish it without incident. You can either reseat the loose washer or replace it with the correct size.

How to fix a whistling kitchen faucet

Clean or replace the valves

Before disassembling the faucet, please close the faucet, then remove the handle, and use a wrench or pliers to unscrew the valve fixing nut. When you do this, you may find that the nut is loose, all you have to do is tighten the nut to stop the noise. If not, it’s time to start checking the rubber.

The most likely responsible part is the rubber gasket in the water inlet hole of the valve housing. You can find these on single handle cartridge and ball valve faucets. After disassembling the valve, you can remove it with a screwdriver and replace it. These washers usually have springs and should be replaced, as well as any O-rings and other rubber parts. If the valve is full of mineral deposits, soak it in vinegar overnight.

Clean up the residues

If the whistling faucet is caused by the accumulation of residue, you can use a damp cloth to clean up everything as much as possible. For more stubborn residues, you can use detergents that can remove scale. After completion, you can reinstall the gasket and check whether the result is satisfactory. For mineral accumulation, remove the tap from the sink. Let it soak in vinegar water for a while. This will help dissolve the mineral deposits. This is a cheaper way to solve the problem, rather than replacing it with a new faucet.

Reduce the water pressure

You can test the pressure by screwing an inexpensive pressure gauge onto one of your outdoor spigots. If you have a well, then check the gauge on the pressure pump. A pressure gauge screwed onto a hose bibb can supply you with an accurate reading. You will need a plumber to install a pressure-reducing valve or replace the blocked pipe to solve the noise problem.

Final thoughts

In fact, the problem of a whistling kitchen faucet is not as complicated as you think, you can eliminate the reason one by one and fix it by yourself. If the whistle doesn’t stop after your fixes, it’s time to ask a professional for help. It is important to do so as soon as possible because it may lead to more problems. The more you delay calling for help, the more likely your faucet is to fail, making your maintenance more expensive.
