Rattling sounds coming from your home plumbing are distressing. They can be caused by a host of issues, including faulty pipes, frozen pipes and water pressure issues. If you hear water hammering or a rhythmic knocking noise that comes and goes, it indicates that the water pressure inside your home is lower than the water supply. When this happens, the water inside your pipes is trying to force its way back to the main supply line and the noise is caused by the water hitting the inside of the pipe and causing a knocking sound. This is called water hammer. It is a natural phenomenon that occurs whenever a change in water pressure occurs in a pipe. The phenomenon is common in all types of buildings, especially those with water supply systems that are located some distance away from the building. The frequency and intensity of water hammer will vary depending on the volume and speed of flow through the pipes; the length of the pipes; the change in water pressure; and the amount of air present in the system at the point of pressure change.
Why Does This Happen?
The pressure inside your home is regulated by the water main. When you turn on a faucet or flush a toilet, the water inside your home travels through the supply pipe, which connects to the main. The water inside the supply pipe has a higher pressure than the water inside your home; therefore, it will force the water in your home to flow back towards the supply main. The pressure in the supply main is constant, so as the pressure inside your home falls, the pressure inside the supply main will rise until the two are the same. When this happens, water inside the supply pipes begins to flow back towards your home. This happens most frequently at the end of the day when the water main has been fully used and the pressure inside the house is low. If this flow of water back towards the home is not properly stopped, the pressure will rise again and cause water hammer.

Frozen Pipes
If your pipes become frozen, the air inside the pipes expands as the water freezes, which can cause the pressure in the pipes to drop. This drop in pressure can cause water hammer, especially if the pipes are located near the main supply line. The pipes will thaw out at some point, but it can take a while for the water pressure to return to normal.
Plumbing Problems
If you suspect that you have a plumbing issue, contact a plumber as soon as possible. This will help to reduce the amount of damage to your home and avoid costly repairs in the future. If you cannot find a plumber and must repair your plumbing yourself, it is important to shut off the water supply before beginning work. This will help to prevent water from leaking onto the floors and creating a dangerous situation.
Rusty Pipes
If your pipes are made of iron or steel, they will naturally rust over time. This is a natural part of the aging process, and there is nothing that you can do to stop it. However, this can affect the water pressure in your home, as the rust will expand when it comes into contact with water and create a pressure drop. This can cause water hammer.
Leaking Pipes
If your pipes are leaking, the water pressure in your home will drop. This can cause water hammer, especially if you have an older home that is not properly insulated. To fix this problem, you will need to find the source of the leak and repair it. If you cannot find the source of the leak, you will need to install new pipes.
If you’re still having issues, call a plumber
If you have tried all of the tips above and are still hearing water hammering, you may need to call a plumber to fix the issue. If you do not have a plumber and have a water hammer problem, it is important to turn off the water at the main supply and shut off the water to the house before beginning repairs. This will help to prevent water from leaking onto the floors and creating a dangerous situation.
