“It’s like a foghorn in New England!” That’s when you realize the sound isn’t coming from outside—it’s coming from your plumbing. No one wants to live with an obnoxiously loud foghorn noise in their home, and fixing the issue can seem daunting. Worry not!
In this article, we’ll explore the possible causes of these sounds, learn how to identify their source, and find solutions to silence those eerie foghorn noises for good.
7 causes of foghorn sounds and how to fix it
1. Toilet
When a foghorn sound occurs in the plumbing of a toilet, it is often caused by a phenomenon known as water hammer.
Water hammer happens when the flow of water in the pipes is abruptly halted or redirected, causing the pipes to vibrate and create a loud noise.
In the case of a toilet, this can happen when the toilet fill valve shuts off quickly after flushing.
To solve this issue, you can install a toilet fill valve with a built-in water hammer arrestor.
This device helps reduce the impact of sudden water flow stoppage and minimizes the chances of creating the foghorn sound.
Another option is to adjust the toilet fill valve to ensure it closes gradually rather than abruptly, reducing the likelihood of water hammer.
2. Faucet
When a faucet produces a foghorn sound, it is often due to water hammer.
Water hammer occurs when a faucet is suddenly turned off, causing the flow of water to be halted and resulting in vibrations in the plumbing pipes.
To address this, you can install a water hammer arrestor or a water pressure regulator on the faucet supply lines.
These tools aid in reducing water hammer and related noises by absorbing the shock from sudden changes in water flow.
3. Walls
If you hear a foghorn sound in the walls, it could indicate a problem with the plumbing pipes behind the walls.
Loose or damaged pipes, water hammer, or high water pressure can contribute to the noise.
To solve this issue, start by inspecting the plumbing pipes within the walls for any signs of damage or loose connections.
Tightening loose fittings or replacing damaged pipes can help eliminate potential sources of the foghorn sound.
If the sound persists, you may consider insulating the pipes within the walls using insulation sleeves. This can help reduce vibrations and minimize noise transmission.
4. Water heater
Sediment buildup inside the tank frequently causes a foghorn sound to come from the water heater.
Over time, minerals and debris can accumulate at the bottom of the water heater, leading to popping, rumbling, or foghorn-like noises when the water is being heated.
To address this, it is recommended to drain and flush the water heater regularly.
Flushing the tank helps remove sediment buildup and prevent the accumulation of debris, which can contribute to the foghorn-like noises.
If the problem persists, it is advisable to consult a professional plumber to inspect the water heater and perform any necessary repairs or maintenance.
5. Ground
If you hear a foghorn sound originating from the ground, it may indicate a leak in the underground water pipes.
The sound could be the result of water rushing through a tiny crack or opening in the pipe, vibrating or reverberating like a foghorn.
It is crucial to contact a professional plumber to locate and repair the leak promptly.
Fixing the leak should eliminate the foghorn sound originating from the ground.
6. Washing machine
There are numerous potential causes of a foghorn sound in the washing machine’s plumbing.
When the washing machine’s water valves abruptly shut off, it might be due to water hammer, loose pipes, or an issue with the machine’s internal components.
Malfunctioning valves or worn-out seals can also contribute to the noise.
To address this issue, ensure that the water supply valves connected to the washing machine are fully open.
Partially closed valves can cause water hammer and the resulting noises.
If the problem persists, consider installing water hammer arrestors on the washing machine supply lines to absorb sudden water flow changes.
7. Dishwasher
Similar to the washing machine, a foghorn sound from the dishwasher’s plumbing can be caused by water hammer, loose pipes, or faulty valves.
Issues such as blockages or restrictions in the water supply line or drain pipe can also contribute to the noise.
To solve this problem, start by checking the water supply line and drain pipe for any blockages or restrictions.
Clearing any debris or buildup that may be obstructing the water flow can help eliminate turbulence and the associated foghorn sound.
If necessary, replace faulty valves or worn-out seals within the dishwasher to ensure proper functioning and eliminate the noise.
How can I identify the source of the foghorn sound in the plumbing?
Identifying the source of a foghorn sound in plumbing can be a process of systematic observation and elimination.
Begin by isolating each fixture or area where the sound is audible and narrowing down the potential sources.
Listen closely to pinpoint the exact location of the sound and check for any visible signs of leaks, loose connections, or damaged pipes.
Also, you can try turning off individual fixtures or appliances one at a time to see if the sound stops, helping identify the specific culprit.
If needed, you may consider consulting a professional plumber who can employ specialized tools and techniques to accurately locate and diagnose the source of the foghorn sound.
What components of plumbing are most likely to cause foghorn noise?
- Valves: Faulty or malfunctioning valves, such as fill valves in toilets, shut-off valves under sinks, or supply valves for appliances like washing machines and dishwashers, can cause water hammer and generate foghorn sounds when they close abruptly.
- Pipes: Loose or improperly secured pipes can vibrate and create noise when water flows through them. This can be particularly noticeable in older plumbing systems or where pipes are exposed and not adequately insulated.
- Water pressure: High water pressure can increase the likelihood of water hammer and associated noises. If the water pressure in your plumbing system is too high, it can lead to sudden pressure changes when valves are closed, resulting in foghorn-like sounds.
- Sediment buildup: The accumulation of sediment, minerals, or debris in water heaters or pipes can create disturbances in the water flow, causing rumbling or popping sounds that resemble a foghorn.
- Water flow restrictions: Blockages or restrictions in the plumbing system, such as clogged pipes or partially closed valves, can disrupt the flow of water, leading to turbulence and noises resembling a foghorn.
What is a ballcock valve, and what does it do?
A ballcock valve, also known as a fill valve or float valve, is a type of valve commonly found in toilet tanks.
Its primary function is to control the water level inside the tank and regulate the flow of water during the filling process after flushing.
The valve consists of a floating ball attached to an arm or rod, which is connected to a valve mechanism.
When the toilet is flushed, the water level in the tank drops, causing the floating ball to descend.
As the ball lowers, it opens the valve mechanism, allowing water to flow from the water supply line into the tank.
When the water reaches the desired level, the ball rises, shutting off the valve and stopping the flow of water.
Regarding foghorn sounds, ballcock valves can be related to water hammers, which can produce similar noises.
When the fill valve shuts off abruptly after filling the toilet tank, it can cause a sudden stoppage of water flow, leading to a pressure surge in the plumbing pipes.
This pressure surge can result in vibrations and create the foghorn-like sound associated with water hammering.
Proper adjustment of the ballcock valve or the installation of a fill valve with a built-in water hammer arrestor can help mitigate these pressure surges and minimize the occurrence of foghorn sounds in the plumbing system.

How does water pressure affect plumbing noises resembling a foghorn?
Water pressure plays a significant role in plumbing noises resembling a foghorn, particularly in relation to a phenomenon known as water hammer.
Water hammer occurs when there is a sudden change in water flow or direction, resulting in pressure surges within the plumbing system.
These surges can create vibrations and cause the pipes to vibrate or shake, producing loud noises that resemble a foghorn.
High water pressure increases the likelihood of water hammer occurring.
When water pressure is too high, the force of water flowing through the pipes becomes stronger.
When a valve, such as a faucet or toilet fill valve, is abruptly closed, the sudden stoppage of water flow creates a pressure wave that travels through the pipes.
This wave can cause the pipes to vibrate and generate the distinct foghorn-like sound associated with water hammering.
In such cases, reducing water pressure can help alleviate or prevent the occurrence of foghorn noises.
Installing a water pressure regulator can help control and maintain the pressure within a safe range.
A regulator will reduce the incoming water pressure to an appropriate level, minimizing the force of water flow and reducing the chances of water hammer and associated noises.
Do certain weather conditions affect plumbing sounds resembling a foghorn?
Certain weather conditions can potentially affect plumbing sounds resembling a foghorn. Here are a few factors related to weather that can contribute to these sounds:
- Temperature changes: Significant temperature fluctuations can cause expansion and contraction of plumbing pipes. When pipes expand or contract rapidly, it can create movement and result in noise, including foghorn-like sounds. This is particularly noticeable in exposed pipes or areas where temperature variations are more pronounced, such as during extreme weather conditions.
- Humidity and moisture: High humidity levels or excessive moisture in the air can contribute to the development of condensation on pipes. Condensation can drip and create water droplets, which may lead to water hammering when they hit a surface or accumulate in a certain area. A water hammer can then generate foghorn-like sounds.
- Frozen pipes: During cold weather, plumbing pipes exposed to freezing temperatures are at risk of freezing and potentially bursting. When water freezes within the pipes, it can create blockages and increase pressure within the system. When the ice thaws or water starts flowing again, the sudden change in pressure can result in water hammer and associated noises resembling a foghorn.
