What’s Causing My Noisy Pipes?
Noisy pipes can be both frustrating and concerning. Whether it’s a loud banging, a persistent hissing, or an unexpected gurgling sound, these noises often indicate that something isn’t right with your plumbing system. Understanding what these sounds mean and how to address them can help you prevent more serious issues down the line. In this blog, we’ll explore the common reasons why your pipes might be making noise, what those sounds could indicate, and how to effectively fix them.
Common Causes of Noisy Pipes
Noisy pipes can be both frustrating and concerning. Pipes can produce a variety of sounds, each pointing to a specific issue within your plumbing system. Noisy pipes are a common issue in many homes, often indicating problems such as high water pressure, loose pipes, or blockages. Here’s a closer look at some of the most common noises and what they might mean:
Banging or Hammering Sounds
A loud banging or hammering noise when you turn off a faucet or appliance is one of the most common complaints from homeowners. This noise, often called “water hammer,” happens when the flow of water is abruptly stopped, causing a shockwave to travel through the pipes.
Causes:
- High Water Pressure: Excessively high water pressure can cause water to slam into the valves and fittings, creating a loud bang.
- Loose Pipes: If pipes are not properly secured, the force of the moving water can cause them to bang against walls or other structures.
Solutions for Water Hammer Noise:
- Install or Replace an Expansion Tank: An expansion tank helps absorb the excess pressure caused by water hammer, reducing or eliminating the banging noise. Learn more about water hammer solutions from HomeTips.
- Install or Replace a Pressure Reducing Valve (PRV): A PRV can lower the water pressure in your plumbing system, which can prevent water hammer by reducing the force with which water flows through your pipes. Over time, PRVs can wear out or go bad, so if you’re experiencing water hammer and already have a PRV installed, it might be time to replace it. For installation assistance, contact GPS Plumbing. This guide will help you understand the importance of pressure reducing valves and how they protect your plumbing system from high water pressure.
Hissing or Squealing Sounds
A hissing or squealing noise from your pipes usually signals an issue with water pressure or a partially closed valve.
Causes:
- High Water Pressure: Noisy pipes can occur due to water pressure is too high, it can cause a hissing sound as it forces its way through the pipes.
- Partially Closed Valves: If a valve isn’t fully open, it can restrict water flow, resulting in a squealing noise.
Solutions for Hissing or Squealing Sounds:
- Check and Adjust Water Pressure: Use a water pressure gauge to check your home’s water pressure. If it’s too high, consider installing a pressure reducing valve (PRV) or expansion tank to bring it down to a safe level. Visit Moen for more details on water pressure regulation.
- Fully Open Valves: Ensure that all valves in your plumbing system are fully open to allow proper water flow.
Squealing Sounds from Toilet or Faucet
Squealing sounds can be particularly common in toilets and faucets, often indicating issues with specific components.
Causes:
- Toilet: A squealing sound from the toilet often indicates the need for a new fill valve. If the noise persists, it may be due to high water pressure, in which case a pressure reducing valve or expansion tank might be necessary to regulate the pressure.
- Faucet: If the squealing noise is coming from a faucet, it’s likely due to a faulty cartridge within the faucet. Learn more about replacing faulty cartridges from Delta Faucet.
Solutions for Squealing Sounds from Toilet or Faucet
Solution for Toilet:
- Replace the Fill Valve: If your toilet is making a squealing sound, the first step is to replace the fill valve. You can purchase a universal fill valve at most hardware stores and follow the included instructions to replace it yourself, or contact GPS Plumbing for professional assistance.
- Check Water Pressure: High water pressure can exacerbate the noise in your plumbing system. Installing a pressure reducing valve (PRV) or an expansion tank can help regulate the pressure in your home. This is a more advanced task that may require the expertise of a plumber to ensure proper installation and adjustment. Learn more about your homes recommended water pressure.
Solution for Faucet:
- Replace the Faulty Cartridge: Squealing noises in faucets are often due to a faulty cartridge. Replacing the cartridge can usually resolve the noise issue. If you’re dealing with a Delta Faucet or another brand, you can find replacement cartridges at your local hardware store or follow brand-specific guides. If you prefer professional help, GPS Plumbing can replace the cartridge and ensure everything is functioning correctly.
PRO-TIP
Inspect the Aerator: Sometimes, debris in the aerator (the small screen at the end of the faucet) can cause noises. Unscrew the aerator, clean out any sediment, and reattach it to see if this resolves the squealing.
Gurgling or Bubbling Sounds
Gurgling or bubbling noises are typically associated with drainage issues and often occur when water struggles to flow through your pipes due to a blockage or a problem with the venting system.
Causes:
- Clogged Drains: A partial blockage in the drain can cause water to gurgle as it tries to pass through.
- Blocked Vent Pipes: Vent pipes allow air to flow through your plumbing system, which helps water to drain properly. If a vent pipe is blocked, it can cause gurgling sounds.
Solutions for Gurgling or Bubbling Sounds:
- Clear the Blockage: Use a plunger or a plumber’s snake to remove any clogs in your drains. For more tips, read our Ultimate Guide to Clearing Drains.
- Check Vent Pipes: Ensure that your vent pipes aren’t blocked by debris, nests, or other obstructions that could hinder proper drainage. However, it’s important to note that vents are typically not the cause of drainage issues in about 80% of cases.
Tapping or Clicking Sounds
Tapping or clicking noises are often the result of thermal expansion, where pipes expand and contract due to temperature changes.
Causes:
- Thermal Expansion: As hot water flows through your pipes, they expand slightly, and when they cool down, they contract. This expansion and contraction can cause the pipes to tap or click against walls or joists.
Solutions for Tapping or Clicking Sounds:
- Insulate Pipes: Wrapping pipes with insulation can reduce movement and cushion the pipes, minimizing tapping sounds. Find more about pipe insulation at The Home Depot.
- Reposition Pipes: If possible, move pipes away from walls or other structures that might amplify the noise. However, in many cases, pipes inside walls cannot be easily accessed or secured.
Special Note: Air Conditioning and Bathroom Sink Noises
During warmer months, you might notice a whooshing noise coming from your bathroom sink when the air conditioning is running. This sound is typically normal and is caused by airflow interacting with your plumbing system.
What’s Normal:
- Whooshing Sound: A steady whooshing noise is usually nothing to worry about. It’s just the air conditioning system affecting the pressure in your pipes.
What’s Not Normal:
- Gurgling Sound: If the whooshing turns into a gurgling noise, this could indicate that your sink is starting to back up. Gurgling usually means there’s a blockage somewhere in the drain or vent system, which can prevent proper drainage and lead to more serious issues if not addressed.
Solutions for AC Condensate Drain Noise:
- Monitor the Noise: If you hear gurgling, try running water in the sink to see if it drains slowly or backs up.
- Check for Blockages: If the sink drains slowly, you may need to clear the drain or check the vent pipes for blockages.
- Call GPS Plumbing: If the gurgling persists, it’s time to contact GPS Plumbing. We can inspect the system, clear any blockages, and ensure your plumbing is functioning properly. Learn how to prevent and address AC condensate drain clogs with these helpful tips to keep your system running smoothly.
