How do I stop my water pipes from whistling?
An easy way to eliminate whistling water pipes is to install a water pressure valve. Often, the water supply company can install this type of valve, which will reduce the water pressure and eliminate the whistling and hissing noises of behind your walls and ceiling.
High-pitched whistling from the plumbing is caused by excessive water pressure or flow speed. If your water pressure exceeds 60 psi, it's likely the pipes will give a high-pitched noise. The easy fix for high-pitched plumbing noises is lowering the water pressure to an appropriate level.
If you hear whistling from your pipes — even when no water is running — then you may have a blocked drain vent. Depending on how blocked your drain vent is, air could create a whistling sound as it flows past the blockage. This creates whistling noises when no water is flowing.
Whistling or squealing water pipes results from water being forced through a smaller opening than the plumbing components were designed for. This is often due to: water pressure too high, wear & tear on plumbing components, water mineral build-up from the water, or other types of degradations.
Your faucet's nozzle contains a rubber washer that can wear out over time or simply become misaligned. When that happens, running water can start to make a whistling noise. You can try to move the washer back into position yourself by unscrewing the faucet nozzle and adjusting the washer.
If the water pressure in your home gets too high for your house's plumbing system capacity, your pipes can literally start to vibrate, much like a car traveling very fast down an open highway. If the water is running, you might start to hear a hum coming from your pipes.
Fortunately, noisy pipes are not often cause for concern if dealt with properly. The issue usually lies with simple issues that you can either handle yourself, or that can be dealt with through a routine call-out.
Turn on both the hot and cold water to about 1/8th of the way on all the faucets. Leave the water running for about two minutes. Start from the lowest faucet in the house to the highest faucet. This allows the water pressure of the system to force all of the air from the pipes and out through the faucets.
There's air in your pipes: If your pipes make a funny moaning or whining sound when you turn on a faucet, it could mean that there is air caught in your pipes. If this is the case, something is up with your bleed-off system.
Humming. If your pipes sound like they're humming, it's likely a water pressure issue.
How do I lower the water pressure in my pipes?
If you tighten the screw the water pressure will be more and if you loosen the screw the water pressure will be less. Turn the screw clockwise to tighten it and increase the pressure, or turn it counterclockwise to decrease the pressure. Do not be too hasty.
These ballco*ck valves come with an armature and ball that begin to vibrate when the toilet tank refills after flushing. This vibration of valves causes the whistling sound that you hear. The valves vibrate due to a damaged fill valve gasket, or it could also be due to simple wear and tear that has worn down the valve.
Limescale is clogging your showerhead pipe.
The movement of water pushing through this narrow passage at a high speed can cause a high-pitched squeal. Solve this problem by removing your shower head and cleaning the pipe with a solution that will dissolve the minerals without harming the metal.
Air in water pipes will sound like a hiss or pop. Alternatively, the trapped air can cause loud gurgling and prolonged vibrating noises. Other sounds are loud noises and bangs emanating from the pipes; this clearly indicates air traveling in the pipes.
Whining. Taps usually whine when your pipes are dented or have air in them. The simplest way to try and fix your tap if it's whining is to start by turning off the main water supply, which will be under the tap or on the outside of your home.
You need a new aerator – Mineral deposits in the aerator—the screen which screws into the tip of the faucet—could be the cause of your noisy faucet. Unscrew the aerator and run the faucet. If the noise disappears, buy a new aerator and install it.
