Loud Water Pipes in Apartment: How to Get Some Peace and Quiet

Loud water pipes in an apartment can be a major source of disturbance, affecting the quality and comfort of life for those who live there. The noise from these pipes can range from mild annoyance to extreme disruption that impacts sleep and concentration.

To solve this issue, it is important first to diagnose the cause of the loud water pipes in your apartment. Common causes include high water pressure, loose fittings, corroded pipes, and inadequate insulation.

There are both DIY solutions for each of these potential causes and when it may be necessary to call a professional for assistance. This blog post will discuss the primary causes of loud water pipes in apartments, providing tips on how to diagnose the source of the noise, as well as DIY solutions and when it is necessary to call in a professional.

Identifying the source of the noise

Common causes of loud water pipes in apartments

In an apartment, loud water pipes can be a real nuisance. The noise source can vary, but some common causes contribute to this problem.

  • High water pressure is often the cause of loud banging or knocking noises when too much force is exerted on the pipes by high-pressure lines or faulty pressure-regulating valves.
  • Loose fittings can also create a loud rattling or knocking sound as the water flows through them. This can be due to age and wear or improper installation of pipes, valves, elbows, tees, and other fittings.
  • Corroded pipes may whistle or hiss because of leaks caused by various factors, including pH levels, water type, and temperature, as well as the age of the pipes.
  • Insufficient insulation on pipes can create a loud humming or buzzing noise if they are located in uninsulated areas such as basements, attics, or crawlspaces.
  • Water hammer is when pressure waves cause loud banging noises due to sudden stoppage of water flow, which can occur when valves are closed too quickly or when appliances such as washing machines shut off abruptly.

How to determine the specific cause of the noise in your apartment

Leaking water pipe

It’s important to identify the cause of the noise to take steps to fix the problem. Some ways to do this include:

  • Listening for specific sounds: The type of noise can often indicate the source of the noise. For example, a hammering sound is typically caused by high water pressure, while a whistling noise is often due to a leak. Additionally, humming noises could be caused by a lack of insulation, and banging noises may be from a water hammer.
  • Checking water pressure: You can check the water pressure in your home using a pressure gauge found at most hardware stores. If the water pressure is over 80 psi (pounds per square inch), it may contribute to the noise. To see any variation, you can also test the pressure at different points in your apartment, such as in the kitchen and bathroom.
  • Inspecting pipes and fittings: Visually inspecting the pipes and fittings in your home can help you identify any loose or corroded parts that could be causing the noise. Check for leaks, rust, or other signs of damage. Pay close attention to pipes and fittings in areas where you hear the most noise, such as in the bathroom or kitchen. Also, check if any pipe supports have become loose or if any pipe insulation that has been damaged.
  • Tracking the noise over time: Keeping track of when the noise happens and how long it lasts, as well as what you were doing when it occurred, can help narrow down the source. This could provide clues if it is happening at certain times, such as when you turn on a faucet or when the washing machine is running.
  • Checking with your neighbors: If the noise is loud enough, it may bother your neighbors. Reach out to them and see if they have heard the noise too. If so, working together to find the source of the noise could be beneficial in solving the problem.

DIY solutions for quieting the pipes

Installing water pipe insulation

Dealing with loud water pipes in an apartment can be a frustrating experience, but there are some simple and inexpensive solutions that homeowners can try.

  • Adding pipe insulation: Wrapping pipes with insulation is one of the easiest ways to dampen noise as the water flows through them. This can be done using fiberglass or foam insulation found at hardware stores or pre-slit pipe wrap insulation.

  • Securing loose fittings: Ensure all fittings are tightened properly with a pipe wrench or pliers to prevent rattling and knocking noises.
  • Installing a pressure-reducing valve: To lower the water pressure and reduce banging noise, install a pressure-reducing valve found at most hardware stores.
  • Reducing water usage is another way to reduce noise by taking shorter showers, fixing leaks, and not running water unnecessarily.
  • Adding pipe hangers: If the noise is caused by pipes vibrating, pipe hangers can help isolate them from the structure.
How to hang your pipes
  • Water hammer arrestors: A plumber can install water hammer arrestors to reduce the loud banging noise caused by a water hammer. These devices control the pressure waves, thus mitigating the negative effects of water hammer. They can be found in most plumbing supply stores and should be considered for any home or business experiencing issues with water hammers.

While these solutions may not eliminate the noise completely, they can help reduce it. However, if the noise is caused by severe corrosion or other major issues, it’s best to call a professional plumber.

When to call a professional

  1. If the noise is caused by corroded pipes that need to be replaced: Corroded pipes can develop leaks, which can cause a loud whistling or hissing noise. If the pipes are severely corroded, they may need to be replaced to fix the problem.
  2. If the water pressure is too high and cannot be easily adjusted: High water pressure can cause loud banging or knocking noise. If the pressure is too high, it may not be possible to adjust it with a pressure-reducing valve. A professional may need to be called to assess the problem and make necessary adjustments.
  3. If you cannot locate the noise source: If you have tried all the solutions and are still unable to locate the source, it may be necessary to call a professional who can use specialized equipment to locate the problem.
  4. If the noise is so loud that it is causing disturbance to your neighbors: If the noise is loud enough, it may be disturbing your neighbors. Reach out to them and see if they have heard the noise too. Collaborating with them may help you find the noise source and call a professional to fix the problem.
  5. If the problem is with the building’s main water supply: If the noise is happening in all of the apartments, it may be necessary to contact the building management or landlord to have them investigate and fix any issues with the main water supply.
  6. If you are unsure about the cause of the noise and the solution: If you are unfamiliar with plumbing and uncertain about the source, it is best to call a professional who can properly diagnose the issue and suggest an appropriate solution.

In general, it’s always recommended to call a professional if you are unsure about the cause of the noise or if you cannot fix the problem yourself. A professional will have the knowledge and expertise to identify the noise source and make any necessary repairs.

When to inform building management/landlord

If you’ve identified the noise source and it continues to persist, or if there is an issue with a shared pipe or common area, it’s time to call your landlord. Be sure to explain the problem clearly and provide any details that might help them diagnose it quickly and accurately. Your landlord may refer you to their maintenance team or hire an outside contractor if they feel it is necessary. Depending on the severity of the problem, they may even offer compensation for any inconvenience caused by the noise. 

It’s also important to note that some cities have laws regulating maximum noise levels for residential buildings. So, if your landlord isn’t taking action quickly enough, consider contacting local authorities for assistance. The last thing you want is for your neighbors to become frustrated with excessive noise levels coming from your apartment! 


Loud water pipes in an apartment can be a nuisance and disrupt daily life. Identifying the noise source is the first step in finding a solution – this can often be done with simple and cost-effective solutions such as pipe insulation, securing loose fittings, installing a pressure-reducing valve, or reducing water usage. If these don’t work, it may indicate the need for professional help due to more serious issues such as corroded pipes or high water pressure. If unsure of the cause, always consult a plumber to find the best solution to reduce noise from loud water pipes.
