Replace Old Pipe Mounts: When you run hot water through your pipes, they can start to expand, leading them to bang against your pipe mounts. If this is happening in your home, you can easily solve the problem by installing plastic pipe clamps that enable expansion without the loud moaning.
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.
If you're ready to soundproof your water pipes, you have two main options. You can either wrap the pipes with noise blocking materials or fill the cavities around the pipes with sound absorption products. Using both noise blocking and sound absorption materials can eliminate the sounds of pipes in your home.
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.
The easy fix for high-pitched plumbing noises is lowering the water pressure to an appropriate level. Residential water supply lines work best around 50 psi at the water-main. If the water pressure in your home is suddenly higher than it used to be, your pressure reducing valve may be work out or broken.
A foghorn sound in your plumbing could be a number of things. It may be a faulty ballcock in the toilet, a loose faucet washer, or a valve in the washing machine. It may also be permeating your entire house, in which case it could be from loose or old pipes or a malfunctioning regulator.
To resolve this problem, you can tighten the screws or replace the washer. If the sound continues or gets even louder, call a plumber. Inside the Walls: Sometimes it is difficult to discover where exactly the foghorn sound is coming from and it can oftentimes be coming from behind your walls.
To make matters worse, loud noises coming from your piping can actually be an indicator of a bad plumbing problem or series of plumbing problems in your pipes. If left untreated, these clogging and drainage issues can become disastrous over time.
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.
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 banging noise you hear is the result of vibrations in pipes.
Water Hammer
When you flush the toilet, it opens a valve to allow more water in. Water hammer happens when the valve suddenly shuts off, resulting in water with no place to go. This incident causes the excess water to hit the walls of your pipes at high speed, resulting in a rattling or hammering sound.
If your pipes sound like they're humming, it's likely a water pressure issue. When the water pressure is high, it can cause the water pipes to vibrate and create a humming sound. High water pressure is more common if you have a well for your water, but it can happen with municipal water as well.

We've all heard strange noises (bumps, creaks, clinks, and clanks) in our house at night. Most of these sounds can be safely ignored. But if you hear banging noises coming from your water pipes, listen up. They could indicate that you have a serious plumbing issue.
Sometimes pipes will moan because there is a valve that is not fully open. Check under your sinks, toilets, and washing machine, and make sure that all of the valves are all the way open. Ask your neighbors to check theirs, too. Check the main water supply valve to the house, too.
Check Your Water Heater
Sediment buildup in your water heater is the most common reason for inexplicable banging noises when there's no water running. It may be loud enough that the echoes carry and cause it to seem like the knocking noise is coming from the pipes in the wall.
If you're hearing banging noises at random, even while no water is running, it's likely that there's some sediment buildup at the bottom of your water heater. If this is the case, what you're hearing is the resulting reverberations of steam bubbles coming out of that built-up sediment.
