If you hear a vibrating, banging or pounding noise when taps are turned on or off it’s usually due to hydraulic shock in your plumbing pipework. Hydraulic shock is more commonly known as “water hammer”. The vibrations are caused by a surge of pressure in the plumbing system when a tap or valve is opened.
How do I stop my taps from making noise?
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.

Why does my faucet sound like a jackhammer when I turn it on?
The thumping sound often heard when water to a faucet or other plumbing fixture is turned on or off is called water hammer. It almost sounds like a jackhammer in your walls and it’s caused by a sudden change in water pressure in the pipes.
Why do pipes make noise when water is turned on?
Only a hot water pipe is capable of making a squeaking sound, and this is due to the heat of the water causing the pipe to expand as the water passes through it. According to Trinity Plumbing LLC, expansion of the pipe causes it to rub against the anchoring straps, creating the squeaking sound.

A: The banging racket you’re hearing is called “water hammer,” a form of hydraulic shock that occurs when the shut-off valve on a high-pressure water line suddenly closes. Fortunately, homeowners can usually eliminate water hammer inexpensively without the help of a professional.
Can water hammer burst pipes?
The Water Hammer Problem The effect of the shockwaves can damage the pipes and knock them loose, and also damage taps, faucets, and appliances. Enough force from water hammer can even cause pipes to burst. If you hear rattling sounds along with the water hammer, it likely means you have pipes coming loose.
Why does it sound like my pipes are shaking?
When water pressure is too high, water pipes can vibrate randomly. This is because the increased pressure within the lines has caused pipe fittings to loosen. To troubleshoot this issue, you need to check your water pressure regulator. Keep water pressure set between 40 and 60 psi – adjust the regulator if necessary.
What does air in pipes sound like?
Noisy water pipes caused by air will sound like vibrating and rapid ticking. The sound can be loud and annoying. By increasing the water’s velocity in the pipes for a short time, you can quiet those noisy pipes.

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.

Why is my kitchen tap making a noise?
A common issue that causes the “faucet vibrating noise” is when the water supply valves to the faucet are not completely open. When this happens, the water that flows through the valve is constricted and vibrates the inside of the valve. This reaction then vibrates the faucet and makes the common hammering noise.
Is there air in my water pipes?

Can low water pressure cause noisy pipes?
Common Causes of Water Pipes Humming Noises If the humming sounds like it’s coming from inside the building’s walls or from all taps and appliances (rather than one isolated fixture), it’s probably caused by a water pressure issue.
