If you are 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.
What you may be hearing is the result of high water pressure on your system. If the city mains pressure is high or fluctuating high it can transmit through your system and cause noise in your piping system. If you have a pressure regulating valve on your incoming water line check it and see if it is working.
Securing loose pipes, checking your home's water pressure, and scheduling regular plumbing maintenance are straightforward actions that can make a big difference. These preventive measures can go a long way in reducing the risk of water hammer, helping to keep your plumbing system quiet and in good working order.
High water pressure is one of the most common reasons why pipes make noise. Even if pipes aren't loose, water pressure over 80 psi can cause them to shake and knock into other materials. Worse yet, high water pressure can damage your pipes, resulting in leaks or bursts.
Fasten vertical pipes and risers using pipe straps or clamps made from malleable metal to prevent movement and noise. Foam rubber insulation can help reduce vibrations and squealing sounds. Monitor the house water pressure, keeping it within the safe range of 40 to 60 psi to avoid noisy pipes and potential damage.
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.
To fix waterlogged air chambers, the air needs to be resupplied to the chambers. This can be done by turning off the water supply coming into your property at your stop valve, normally found under your kitchen sink. Once you have done this, turn on all the taps to drain any remaining water from the system.
You may also hear your pipes humming or squeaking. Though the sound may seem serious, some noises are an indication of minor plumbing issues that need some simple tweaking to correct. However, even minor issues should be corrected as soon as possible to prevent more serious problems from developing.
Start by using a plunger to try and clear any basic blockages. This can often solve simple clogs. If that doesn't work, the next step is to check the P-trap under the sink. Cleaning out the P-trap can often remove debris that causes clogging.
In conclusion, the presence of water gurgling in your walls should not be ignored, as it often signals underlying plumbing issues that require professional attention.
Air trapped inside your plumbing system can also cause pipes to knock. This usually happens when water is being drained from your system or if there is an issue with your plumbing's air chamber. Air pockets can create a knocking sound as water passes through the pipes, even when no faucets are on.
Today, acoustic isolation pipe supports are the key to preventing noise problems stemming from vibrations, effectively dampening the noise transfer between piping and building structures.
Excessive or irregular water sounds may indicate potential issues within your plumbing system. Gurgling, hissing, or constant water flow noises when no fixtures are in use could be a sign of a leak, water pressure problems, or issues with the water supply line.
If you are 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.
Can noisy pipes burst? Yes. This is especially true if the noise is caused by high water pressure or loose pipes. If you hear your water pipes making noise, it is important to deal with that immediately.
Average Flat Rate
Some plumbing jobs are billed at a flat rate. As of 2025, the average plumber rates for larger repairs are typically between $500 to $800, while smaller jobs like repairing toilets, sinks, faucets, or bathtubs typically range from $125 to $350.
To fix the issue, you need to replenish the air supplies of the chambers. Doing so will silence those noisy pipes. Additionally, installing water hammer arrestors can help mitigate the banging noise caused by water hammer.
Noisy Pipes: Hissing, knocking, or gurgling sounds even after bleeding the air can be signs of a more serious problem like water hammer or damaged pipes. Leaks: If you notice leaks while attempting to remove an airlock, stop immediately and call a plumber.
Tighten or Add Pipe Straps: As time goes by, your pipe straps will inevitably loosen, allowing pipes to creak and moan as your water temperature fluctuates. Combat the creaks by either adding additional straps or tightening the existing ones to keep pipes secure.
Typically, banging noises coming from your pipes infer an issue with water flow or water pressure. Two of the most common causes are water hammers and trapped air bubbles. A water hammer, also known as hydraulic shock, occurs when fluid in motion is suddenly stopped when a faucet or valve is shut off.
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.
Head outside to the water spigot, remove the hose, and screw the test gauge onto the spigot, ensuring the face of the gauge is visible. Turn the spigot valve on and check the reading. This will indicate the amount of pressure coming into your home (from a public utility system or a well).
